  1. Since I've seen some questions on this I took some pictures and will provide instructions on a valve adjustment for the UT400. This should be the same for the 550's and other various Coleman/Hisun single cylinder models with the cylinder slanted aft. I have seen several people ask of it is really necessary, and read several reports of valves being out of adjustment from the factory. My valves were .004" intake, and .010" exhaust with about 5 hrs on the machine. I've seen different numbers thrown around for factory spec, but I decided to go with 0.005". This is called valve lash. What is is is a gap between the rocker arm and the valve then the camshaft isnt opening the valve. Why does it matter? If it's too large the valve doesn't open all the way, if it's too small the valve dosent close. This can cause valve damage (overheating) as well as loss of engine power (burned fuel is going out exhaust rather than pushing the piston dow). Tools required : 5MM Allen wrench, 10MM box wrench, needle nose pliers, flat feeler gauge set, rags First you need to remove the fan cover on the passenger side. There is a cooling vent hose on the back side, remove the hose clamp and slide it off. From there there are 4x 10mm bolts holding the cover. The forward ones can be accessed from under the seat. Next remove the spark plug from the drivers side. Carefully wiggle the spark plug wire off. Grip it as low as possible and give it a little twisting motion as you pull it off to help free it. Its a tight fit for a socket, but there is a sheet metal wrench in the toolkit that fits it. Unscrew the plug and set it aside. This allows you to spin the motor over freely with no compression to fight. When you reassemble this is a good opportunity to switch to an NGK iridium plug for better performance/less fouling DR8EIX) Next you need to remove the intake and exhaust valve covers. The intake us the forward one. There are 3x 5MM Allen screws to remove. The Exhaust is the rear with 2x 5MM Allen bolts. Both covers have O-Rings instead of gaskets and are reusable. When you remove the rear be careful and use your rags as there will be oil that drips out. Next up we need to spin the motor over to top dead center. Grab each rocker arm and give em a little wiggle up and down. Spin the engine over by grabbing the fan with your other hand. Spin the engine over until both rockers have some wiggle and are loose. Once both rockers are loose slide the feeler gauge in like shown above. Try different feelers as needed to determine your starting spec. You should feel some drag but still be able to move the feeler without too much force. If you need to adjust, use the 10MM wrench to slightly loosen the locknut, then with the correct feeler gauge in place, tighten the top square nut while wiggling the feeler in and out. Once you have it right you need to tighten the 10mm lock nut without moving the square head bolt. Once the lock nut is tight recheck the clearance. That's it, button everything back up and make sure you have it all reassembled before running it again. If you find this helpful give me a thumbs up or comment. If you have any questions or need more help let me know. If there's interest maybe I'll do some more of these

  2. In order to connect with the ECU we need two cables. The first is a USB ODBII cable. HUD ECU Hacker’s documentation has a lot of different confusing options, but here’s what I went with and managed to get working, the cable is called “VAG KKL” it is a USB to ODB2 cable. It is available from a variety of sources for $10-15. The second thing we need is a “6 pin delphi to ODB2” adapter cable. It is also available for a similar price. In my case I ordered both from ebay, but there are other sources. Once we have our cable in hand we need to find the plug it in on your machine. My personal rig is a Coleman UT400, but the wire location should be similar for all Hisuns. My cable was located under the middle of the seat area. Just inboard of the battery, where the main wire harness split loom runs. The cable is a 6 pin (3x2) with a dust cap. Remove the dust cap and plug in the 6-pin end of the Delphi adapter cable. Note: When I was done, I left the 6-pin adapter connected, and zip tied it so it now runs to in front of the battery for easier access in the future. Next download and install HUD ECU HACKER DOWNLOAD Open HUD ECU Hacker on your PC It should prompt you to choose a driver to install. This particular cable uses the “CH340” driver (First choice on the menu) click to install, once installed hit the X in the corner to go back to the main page Once the driver is installed plug in the USB Cable, and plug the ODB2 end into the 6 pin adapter. The red led on the adapter should light up indicating it has power. Drop down and pick a com port on the main screen, it should show the VAG KKL adapter as a com port. Click connect on the main menu. It will pop up a bunch of fast scrolling text indicating it is connecting. Once connected you can click through the various tabs to see different data sets. The main menu also has the option to show fault codes, clear fault codes, reset the EPROM back to factory. The other function that may be helpful is recording a log file. You can record a log while operating the unit, and come back later and replay it to try to better diagnose what is happening. Within the various pages you will see the reading from each sensor. Sometimes a sensor reading will be off enough to cause running issues, but not enough for the ECU to realize its an issue. For example if the engine thinks it’s really warm, but its actually cold, it may not inject enough fuel to start. There are also more advanced functions, like adjusting fuel mapping, but that is beyond the scope of this tutorial.

  3. White smoke is usually coolant leaking into the cylinder. Sounds like a blown head gasket to me.

  4. Just wanted to give update . It was the ecm. Put new one on and got spark immediately to front cylinder. Ran but smoking and no power. I checked back cylinder and no fire. Pulled coil to check with meter and found wire was not getting good connection where it plugs into coil. All good now . She will scream !!!. Next is to figure out why 4x4 switch wont turn. Thanks for all the imput....

  5. Hello to anyone who reads this. I am Jon and I own J&M Outdoor Power, a very small, small engine repair shop. I was approached by Coleman about 6 months ago to become one of their Warranty Centers. I recently received 3 different UT400's and a UT500 all with similar issues. These units range from 2 months to 2 years old. Customers state that the unit(s) was/were running fine, then heard a pop and a loss of power, two would no longer start. The two that would run would not achieve normal operating speed (around 20mph I would say) without redlining the RPMs. I quickly found that the Valve lash on each unit had become too large on some(both intake and exhaust) and too tight on one(just intake). After setting the gaps to .005(I found multiple different people suggesting bigger and smaller gaps, but no definitive Coleman Spec number yet) every unit starts, runs, and achieves top speed without issue. I don't know how many others have come across these issues, and I wanted to get something out on the web for others in the same predicament. Please let me know if you have had similar issues. Edit: I realize that this will not be a fix all solution for this issue, as the oil level and condition should be verified before moving to the valves. Many times improper oil conditions will cause valve lash to change. These units all have good oil and proper oil changes.

  6. Hello again! I now have a pretty good running Coleman UT400 after a top end rebuild, wet clutch rebuild and a repaired crankcase... ! It plows snow great, but I was also having the jumping out of gear problem, mainly reverse, but a couple times out of forward. I would quickly place it in N and then let the engine idle down and shift again. This worked most of the time. I did some research and found that some have modified the shift linkage. The problem with just adjusting the shift cable is that it really NEEDS more throw, not an adjustment. From what I've read and viewed on the Internet, the linkage arm needs to be about 3/4" longer to gain more throw in both directions. On YouTube, the guy had to remove the shift linkage hole trim and notch the side of the dash to get the shift linkage off the pivot pin. BUT this is NOT necessary. When the "E" clip has been removed and you fish it out of the firewall somewhere, the shift lever is now loose. I had to pop the top of the shift knob off, remove the retaining screw and then heat the lower portion of the knob to get it to come off the lever. Once you have the shift lever loose, push it towards the right to slide it off the pivot shaft. But it won't come off just yet. Use a small pry bar/screw driver and slide the nylon flanged bushing out of the left side of the lever. This lets the lever slide off and get into a "loose" condition and it will twist and come right off without removing the dash trim, that could be a bugger to get back on correctly. Once the lever is off, press out the other bushing so when you're welding on the linkage arm, you don't melt the bushing. I found a piece of scrap metal the same thickness as the lever arm, just over 1/8" thick, close to 3/16". I cut my arm and beveled the edges for better welding. I added a piece just over 5/8" long and kept about a 1/16" gap between the arm and the new piece. Once welded on bother ends, it adds up to just about 3/4" or so. I reinstalled the lever after painting it and did an adjustment on the cable. By the way, it's easier to remove the cable from the bracket on the frame. This gives you more clearance to maneuver in that area with your hands. ALSO, you will need to get a 12" adjustable wrench and slide it over the cable mounting bracket and tweak, to the front, the steel so the cable is pointed upward a bit to now realign with the new longer shift arm lever. There's more than enough metal for the tweak and it will line up perfectly. I now bottom out the shifter on the transmission BEFORE I run out of throw on the shifter... I've tested it just a bit so far and it shifts much better with the longer throw. One of the Coleman authorized repair facilities said that he worked with Coleman to get a new part that's longer by 3/4". He's modified a few and it works perfectly for him. Just doing the cable will just short you on the other end. Here's some pictures of my modified shift lever etc.

  8. There are actually 5 disc brakes on these machines. 1 for each wheel and 1 on the rear driveshaft for the parking brake. I've read several complaints of the parking brake one being too tight from the factory so I would check the cable and make sure there's a little slack when the parking brake is released. If that is good I would jack up each corner Individually and spin the wheel to listen for noise and feel for dragging. That should help pinpoint where the issue is.

  10. Just looked at the Lowes add for that, pretty much looks like an MSU 500/700 that Hisun made for Massimo back then. Take a good look at the badging on parts to see who it's actually made by, my guess is it's still Hisun.

  11. Hey Folks There are not a lot of good sources out there for troubleshooting and diagnosing ECU problems with the Massimo Buck, Bennche Bighorn, Bennche Cowboy, & Cazador machines that use the Delphi MT05 ECU. They are all basically the same with different badging, so I thought I'd share some info that I found during some searches. I was trying to help someone diagnose and repair a hard starting issue. The ignition coil was throwing a 0351 code. I discovered how to read codes without an OBDII code reader. The following procedures should help you check your fault codes and clear them if needed. Fault Code Troubleshooting for Delphi MT05 ECU on the Massimo Buck 400, Bennche Bighorn 400, Bennche Cowboy 400, and Cazador 400 *NOTE: The MT05 ECU is not really OBD 2 compliant. It is much more similar to an OBDI system. The MT05 ECU controls either 1 or 2 cylinder engines commonly found on Massimo, Bennche, and Cazador. Much of the ECU info was found here: https://netcult.ch/elmue/HUD ECU Hacker/Delphi MT05 Manual.pdf Delphi EFI System Design Delphi EFI employs 5 sensors to monitor engine performance. 1. Crankshaft Position Sensor 2. Coolant Temperature Sensor 3. Oxygen Sensor 4. Throttle Position Sensor 5. Manifold Air Pressure/Manifold Air Temperature (MAP/MAT) Sensor Delphi EFI employs the following system components. 1. MT05 Engine Control Unit (ECU) 2. Fuel Pump 3. Multec 3.5 Fuel Injector 4. Idle Speed Control Valve (Idle Stepper Motor) 5. Multec Ignition Coil 6. Fuel Vapor Canister Purge Valve Using the Digital Dashboard to Decipher EFI Trouble Codes In addition to commercially available diagnostic scan tools (Big $$$), you can use the engine warning light of the Siemens dashboard to diagnose most of your EFI problems. The digital dashboard receives signals from the MT05 ECU, and the engine warning light will flash a diagnostic trouble code (DTC) if the ignition key is switched on/off for three cycles. When you turn on the ignition, the engine warning light will illuminate, which indicates the EFI system is operational. After the engine is started, the engine warning light will extinguish if the EFI system is working properly. However, if the engine warning light remains illuminated, it indicates the EFI system is not working properly, and there is a system component failure. Deciphering Diagnostic Trouble Codes To read the diagnostic trouble code (DTC), open and close the ignition key three times in rapid succession, as follows: open/close—open/close—open. At this point the engine warning light will flash a DTC which indicates the fault in the EFI system. Refer to the attached fault code table to identify the corresponding problem. The engine warning light will emit a sequence of flashing lights. If the light flashes 10 times, the translated number is 0. If the light flashes one time, the translated number is 1, et cetera. For example, if the MAP/MAT sensor is disconnected, or the connector is shorted to ground, the engine warning light will flash in the following manner (This is an example only). The engine warning light will flash 10 times: The first number of the DTC is 0 After an interval of 1.2 seconds, the engine warning light will flash 1 time: The second number of the DTC is 1 After an interval of 1.2 seconds, the engine warning light will flash 10 times: The third number of the DTC is 0 After an interval of 1.2 seconds, the engine warning light will flash 7 times: The fourth number of the DTC is 7 The resulting DTC is P0107. NOTE: For the system I was helping to troubleshoot, I suspected an ignition coil failure due to the code that was thrown. When it was checked, it was flashing: 10, 3, 5, 1. The 10 represents a 0. So the actual code was 0351. After finding the code, the coil wire was checked and discovered loose at the spark plug. Once it was pushed fully on, the problem was fixed. Most likely, this problem was created after the owner had pulled the spark plug to check the gap. The ECU was rebooted using the procedures detailed below with no more codes being thrown. If there are other fault codes, the engine warning light will flash the next code in 3.2 seconds after finishing the first sequence. After all existing fault codes are flashed, the engine warning light will repeat the fault codes in a loop sequence, until the ignition key is turned off. To clear fault codes you either need an OBDII Fault Code reader and a Delphi 6 pin connector adapter cable that you have to order from China and wait 8 weeks…OR....you can simply reboot the ECU using the instructions detailed below. Rebooting the ECU Perform the following steps to reboot the ECU. 1. Turn off the ignition for 15 seconds. 2. Turn the ignition on/off for 5 cycles. Make sure each cycle lasts about ½ second, verifying the start of the fuel pump for each cycle. If the fuel pump doesn't start during any cycle, begin the entire reboot procedure from the beginning. 3. Turn off the ignition for 15 seconds. TPS (throttle position sensor) re-learn procedure after rebooting ECU. This should be done after replacing the TPS or the ECU....and it is advisable to check proper idle after rebooting an ECU too. Source: ECU Hacker (Reworded process slightly to make it a more sensible flow in my mind): 1. Turn the idle screw one full turn clockwise before starting 2. Start the engine, and run at low idle until the engine warms. Maybe a couple of mins. 3. Idle should be above 1500 rpm. If it isn’t, turn it up to 1700 then shut the engine off. Do another reboot of ECU. 4. Restart the engine and let it stabilize at 1700 rpm. Then turn the idle screen down to 1500 rpm and let it stabilize for a few seconds. Once it stabilizes, set to the final recommended idle speed for your machine. The placard under (or behind) your seat should show idle speed, valve adjustment, spark gap, etc. Typically the 390 cc engines in the "400" machines run at 1600 rpm idle. 5. Shut it down. Wait 10-15 seconds before restarting. The procedure is now complete. Final Notes: I have included pictures of an OBDII connector and the Delphi 6 pin connector in case anyone wants to go buy stuff off ebay or local parts suppliers and build a connector to use for an OBDII reader. But...you can save money and simply do the same thing with code reading and resetting using the check engine light on your dash. Some folks prefer to do it with code readers. Hope the information provided helps if anyone ever needs it but cannot find it in repair manuals. I discovered most of this in some motorcycle forums. The source for the diagrams is here: https://netcult.ch/elmue/HUD ECU Hacker/ Be advised: I am not a service technician. I do not endorse any manufacturers. I do not get paid to help, nor do I want to. This is just a hobby of mine. I enjoy working on things and solving problems. If you run into a weird problem that stumps you, give me a shout. I may be able to give you some ideas...or not. Just know, that troubleshooting thru emails can be challenging. The more info you can provide, the better. Otherwise, I will probably ask you a ton of questions. The good news is, the Delphi system used on these machines is essentially an OBDI and it is very simplistic. If you are methodical and patient, most of your "problems" can be figured out thru a process of elimination. Always go for the simple things first before throwing money and sensors at a machine.

  13. The main trick is tilting the front end up. Block the rear wheels and jack up the front end at least a foot. A convenient ditch works well also.....rear wheels in a shallow ditch. The head bleeder screw should be opened. With the engine NOT running, almost fill the radiator (leave some air to avoid a mess) and burp (squeeze the lower hose line before the metal tube at the engine base passenger side floor area). Watch the radiator and the the bleeder. With the radiator "higher" than the head bleeder, the air should be bled and coolant dribble out. Close the bleeder and refill radiator (your clue you displaced the air with coolant) and start the engine. Burp more while running and if you get the circulation going the hoses will warm up. More bubbles should surface at the radiator filler neck. Shut off engine. Open bleeder and release any air in the head. The puke jug needs to be filled about an inch above the full cold line. Use a shop towel as a "seal"and use an air nozzle to SLIGHTLY pressurize the puke tank removing the air from the tubing line to the radiator neck. Then the radiator starts to overflow, a third hand can install the radiator cap. Run the engine and determine the head and hoses are at the close to the same temperature (as in warming up) through out the system. IR temp gun....fairly cheap now....can get real numbers. Scan the radiator, hoses, cylinder and head.....if all close you are done. Recheck fluids when done riding. Recheck the bleeder and top off the puke jug as required.

  14. Its' not a car, this is a motorcycle engine with a small stator charging system. You can't expect to run high wattage accessories like a heater or huge light bars on these things . That will overwhelm the charging system, drain your battery an stop your engine. Could damage the charging system and voltage regulator too. You only have about 10 amps extra to run any accessories including lights.

  17. I've seen a number of requests for the location of all the grease points on these machines, and there is no definitive list in the manual. This covers the UT400, but other Coleman/Hisun models should be similar. Tools: First to grease your machine you need a grease gun and some NLGI#2 grease. You will find it helpful to buy a needle attachment as pictured here, due to poor clearance on some of the U-joints. The rest of the zerks use the standard attachment. Technique: Wipe any dirt/grease off the zerk before greasing to prevent pushing gunk inside and causing excess wear. Push the grease gun on the zerk at a straight angle and give it a few pumps. You will hear an oozing noise or sea grease coming out from the outside of the greased area when you've put enough grease in, a few pumps should be plenty. If it's just oozing around the zerk you either don't have a good seat with the gun, or the zerk may be rusted and the check ball frozen. Try seating it again and regrease. Wipe up any excess grease when youre done to prevent making a mess. Greasepoints: Rear A-Arms are greasable with the wheels on from the rear, I took the picture with the wheel off for easier visibility That's it. All other Hisuns should be substantially similar.

  18. A few pics and a short write up on my installation of the Ice Crusher heater kit for the Coleman / Hisun 400. Ice Crusher makes a kit for the Coleman 400 which includes a dash mounted heater core mounted in a compact housing that includes 2 heat outlets that can be aimed wherever you want or closed, a built in coolant shutoff valve for summer use and a 3 speed fan. The kit has all needed hoses,fittings,clamps and hardware so you don't need to hunt around for anything else in theory. The unit is well made and everything seems solid and sturdy enough to live in a UTV. Installation is pretty straight forward,raise the front about a foot and start planning where things need to go. Detailed instructions are included as well as a template on where to position the holes where the 2 hoses pass through the "firewall". There are instructions on exactly where to position the mounting screws etc for the heater unit etc. I did encounter a problem with the hose positioning template which positioned the holes about 1" too low and caused a problem with mounting the rear support bracket. I contacted the company and worked with their engineers to amend the template for future buyers. The coolant tap ins are basically cutting the original coolant hoses going to (passenger side) and from (driver side) and installing the supplied 3/4" to 1/2" tee fitting. One 1/2" hose connects to each of the two heater core pipes. The theory is that some of the coolant is directed through the heater,which should be adequate for cab heat. I found that the original radiator is quite large for the little 400 motor and didn't really allow the heater to provide heat for very long before getting too cool to help much. The solution was to add a 3/4" heater shut off valve in the passenger side radiator hose between the tee fitting and the radiator. This allows me the option of directing all of the hot coolant through the heater or a blend depending on conditions. This valve is a cable operated style with a simple push pull knob installed in the dash.Having the front end raised makes it easy to simply refill the radiator without the need to bleed the system. Very effective. After sealing up the soft enclosure, the heater is about as effective as a regular car of truck unit. The blend valve is available at any auto parts store as a kit with the cable and hardware for about $25. I have had zero issues with overheating even when running for a hour on the roads with all the coolant going through only the heater The heater kit sells for $399,which isn't cheap, but I figured with as fully equipped the Colman 400 is at the price I paid ($6999), why not make it as comfortable as possible? https://photos.app.goo.gl/L64ECvfTKDPjje4KA

  19. Paint chip is no good, but doubtful that it made it thru the filter, so it's likely been there, or got knocked off when you were working on removing things. Code 201 indicates that it is getting a weak or unexpected signal from the injector. The fuel metering is done by pulsing the injector open. The ECU expects it to be X resistance and it gets Y resistance instead and throws a code. This could be a failing injector (the internal solenoid may be failing) a loose or intermittent connection, chafed wire partially shorting to ground, moisture or corrosion in a connector, etc. It's likely intermittent, but will eventually get worse. When it's happening it will throw the code and give the engine the wrong amount of fuel causing stalling, performance issues, no start, etc. If it were me I would visually inspect the Injector wiring for chafing, check inside the connectors, and if I didnt find anything just throw a new injector at it. You can also check resistance of the injector, but if it's intermittent it may check out ok when you happen to check it.

  20. I've been looking for a cross to a filter from a known manufacturer since I bought this machine. Both from a cost standpoint, and a known quality standpoint. The factory filters are just plain black with no markings. Due to price point on these machines I would assume that the factory filter would be made as.cheap as possible I have not had any real luck finding a cross, so In doing my first oil change I decided to cut the factory filter and see what is inside. I don't have a fancy oil filter cutting set up, so I just clamped it in the vise and went to town with my portaband. Excuse the rough cuts and metal shavings. Looks like a good quality filter, plenty of pleats/surface area. Metal endcaps. Excuse the crushing, that's from the vise/strap wrench to remove it. Relief valve And a spring in the bottom of the can to keep the top silicone anti-drainback pressed in place. Overall looks like a surprisingly good quality filter for a no name. At least we can know that using the factory filters on these should be acceptable. I feel better about paying $10 for this filter at least knowing it's good quality.

  23. I was under the rig playing today so I decided to adjust the parking brake just to make sure it was ok, since I've read a couple people having them adjusted too tight from the factory. First picture is the parking brake disc & caliper from the passenger side. Second picture is the adjustment bolt. How it works: it's a cable operated disc brake with a locking pawl to hold it where you push the pedal to. Procedure: The pad tightness is adjusted by moving the bolt in the 2nd picture in and out. When you tighten it it pushes the pads together. The extra nut on it is a lock nut. Using a 13mm wrench loosen the lock nut. Back it off about halfway just so it's out of the way. Next tighten the bolt by hand until it stops. From there back it off about a half turn. Push the parking brake and make sure the pedal "locks up" before running out of travel. If it doesn't adjust the bolt slightly tighter and try it again. Once you're happy with the adjustment tighten the lock nut while keeping the bolt stationary.

  26. Really hard to work out what happened. My view would be that it was a loose connection, If it was a battery going up, it would have been caused by a gas explosion and at least one of the batteries would have made a fair noise when it went, but if it was a poor connection then heat could have built up, to the point where the plastics melted and caught . Hard to track it down now, but a quick check of whats left of the cables could show up where one was loose. Such a horrible event. There have been other comments on a FB page when a faulty / inconsistent vehicle turned out to be a poor connection on a battery terminal. Personally I would swap the horrid 10mm headed painted battery bolts for m8x 20 Stainless screws and washers with single springs. Worth regularly checking their tightness. Another alternative cause could be the 12v battery. I have found one that was totally shot. But its not apparent to the user as the DC to DC runs continuously even when the ign is turned off. In this case a duff 12v battery will simply get hot and over heat, when over heating the electrolyte boils off, when plates touch they can spark and ignite the hydrogen inside the battery. My suggestion to users is to get a multimeter go under the drivers seat, find the 12v battery and (behind the drivers legs) and check the voltage (negative is towards the centre positive towards the side panel). Note the voltage. Hit the big red button. That breaks the 48v circuit. The DC to DC will shut down. Leave it for 10 minutes. Re check the 12v battery. If its well above 12v it should be OK , if not then your battery may need topping up , or replacing. If below 12v then its a replacement, as its way under voltage, and probably has one cell dead.

  29. Kawasaki, Polaris and Kubota are what i call "the big three" for utility vehicles... you get the best bang for your buck without sacrificing QUALITY. If you get down to the cheap machines (Hisun, Massimo, Coleman, etc) that are loaded with features and cost only around 9,000.... you're sacrificing quality.

  32. Update on my Axis 700. Contacted Lowe’s to explain what happened. Store manager, Fatima, in Mechanicsville VA was awesome. She paid for my gas for the round trip back which was $170 and then doubled it. She then gave me a new 700 with full tank of gas. It ran good yesterday so we’ll see. I told her if any happens again, I will be taking it to the nearest Lowe’s for a full refund and she said she would make sure it was taken care of. The original 700 did start after a trickle charge. Had to be a bad alternator, or loose wiring. These things do happen. I wish I could purchase a more expensive utv, however I lost my job because I refused to take the vaccine, so I’m on a budget. This definitely fits my budget. Great deal when you add my 10% military discount.

  33. Love mine. Great success dealing with Massimo getting parts. Go to any manufacture's forum and you'll run into same thing... the whinners. Just like here. No one has yet made an indestructible machine. I once worked in a music store and the manger used to say "put a cast iron anvil on the demo floor and someone will make music with it and someone else will break it"

  34. My mother is a hard worker. She's 91. Lately the pain in her legs is so bad it's keeping her from working as hard as she wants. She lives on a 20 acre ranch in Black Forest, Colorado. It's bad enough sometimes she can't walk back and forth to her front gate which is about 100 yards each way. Working hard is her joy in life and she recently broke down crying to my daughter talking about how she feels limited. I want to get her a UTV, soon. She's pretty little only 100 pounds. Money isn't really an issue. This is Colorado and her ranch is at 7500 above sea level so snow is always a factor but with the sun and our atmosphere being so thin snow melts pretty quick. Still I want 4WD as an option or fulltime. I want entering and exiting easy, She doesn't need ground clearance. She will never go trail riding. I'd like to have an enclosed and or removable cabin and heat if possible. Easy start up and do they all have clutches? No clutch or a very light one would help. Some kind of a bed for gardening would be good. That doesn't have to be heavy duty. We're not hauling wood. We have a Kubota tractor I can use for snow plowing. This is just a runabout for the ranch. Even electric would probably work. I don't think we want some no name Chinese thing. I'm around and live about 15 miles away but I can't be there 24/7. We watched a video about Polaris UTV 570 but that's the only video we watched. I frequent other board like those about muscle cars and we're always wary about first time posters especially if they're selling something. I'm not selling but I am a serious buyer and I'm trying to move rather quickly on this. Thanks, Steve in Colorado.

  35. Massimo recently updated their customer support. I know some of us have had less than Stellar response from Massimo in the past but it looks like they've made a major upgrade and taking a big step forward. I entered a a case on their website you can open a case under your account with a broken part under warranty and was skeptical but I got a call back the next day and the tech had me send a picture of the broken part and they shipped out a new part under warranty same-day

  36. Joe, for the record I have never felt bullied by you. As stated earlier, I can understand your anger and frustration with Massimo. Fortunately (for me, anyway), I haven't experienced the same problem that you did. But I also haven't put many miles on it, either. Hopefully it will remain that way, but that's being overly optimistic. I also am fortunate enough to have the Linhai engine vs. the Hisun engine, which I believe you have. You've had a bad experience all the way around, which would cause any of us to look poorly on the make, no matter what that make may be.

  37. I live in a community that has mechanics of all flavors from small gas engines to let's take apart a semi and put it back together. None of them will run gasoline with ethanol in their small gas engines, octane doesn't seem to be the issue, the ethanol gunking up carburetors and fuel injectors is the issue.

  38. Hydrogen combustion and Hydrogen Fuel Cells are the only "green" solutions that makes sense. Too bad finding fueling stations still isn't anywhere close to where we need to be.

  39. I'm having a similar issue with my Coleman UT400, but it started after we left it out in the rain over night (we usually keep it in the garage). We were expecting a large delivery, so needed the garage space for a couple days, and got an unexpected rain shower. When I went to bring it back inside, it turned over fine, but would not fire. I ordered/replaced the CDI, voltage regulator, and coil and still would not start. Cleaned the plug, and it fired right up ... this time. After a few short runs, it quit starting again. The plug was wet fouled with fuel. The same NGK DR8EA as mentioned above. I picked up a couple new ones, but now I have to rotate those in about every 3 starts ... either it won't start, or shortly after starting, it will stall and not refire. Also, when a new/clean plug (I clean them with alcohol and then sandblast them real quick) is put in, it will crank in a couple of seconds, but subsequent attempts will take running the starter motor for 10-15 seconds before it fires. Googling brought me to a page that said Hisuns were bad about bad/dirty injectors causing fouling (I have always run premium with stabilizer in it), so I ordered and replaced the injector too but experienced the exact same issue. Seems like the next thing to try would be the ECU, but that's a little pricey, so I'm hoping for other suggestions before I go there. Now, I did try a hotter plug (DR7EA) and it seems to not foul as quickly, but from the get-go it has taken a lot of cranking on the starter to get it to start up, but seems to run better once started.

  40. It could be a fault in the carb, a lot of the aftermarkets aren't very strict on quality control. the main jet could be oversized a few thousandths and that would affect running. The only adjustments on these Honda carbs, besides the Idle speed adjustment, is the Mixture screw on the side of it, Some of these have them, some of them don't. If your carb has this adjustment screw, the proper way to set it is to warm the engine up, and adjust that screw in or out, until the engine reaches it's highest Idle RPM, that's where the engine is getting the most fuel. you can turn the screw in about 1/16 to 1/8 of a turn that will lean the mixture out just a little bit. you may now need to readjust the idle RPM with the plastic screw on top of the carb. If it still runs rich after this, most likely there is a issue with the aftermarket carb, i had a problem finding a carb to fit the GX390 on my pressure washer, i finally bought a OEM Honda carb.

  41. Actually, the Massimo's are now made by Linhai. Although the grill on my TBoss550 says Massimo, there are Linhai stamped parts everywhere else. But agree with Travis, alot of Hisun owners reporting problems here.

  43. Sounds like the machine thinks it's low on oil. Since it must still be under warranty, I'd let the dealership sort it out.

  44. Do a little reading here on the forums and you'll find lots of issues with the Hisuns from that time frame like mentioned above. I passed on a '16 with fewer miles for the same price.

  45. None, nor electric cars. It is an industry in it's infancy that needs time to mature. Electricity is not an energy source it needs to be generated from energy sources--currently in the civilized world a modestly inefficient process to create AC current, we then carry it, with losses, over power lines to it's application where in the case of electric vehicles we convert it to DC--with losses-to charge batteries to convert that stored energy to motive force (with losses) Direct conversion of an energy source (gasoline) to motive force is modestly inefficient but still in the overall more efficient than all the conversion and transmission loses. In any valid "Well to Wheels" analysis, modern ICE's win every time...

  46. To get the heat shield call Grenada Bad Boys and ask for Mike JR in service. Number is 662-307-2729. A couple positive things about it is they are a Tracker Dealer and they actually use their machines. See item is that the heat shield is hinged to allow you to open it up in the winter when you want that heat hitting your firewall.

  47. That is just normal operation and the same with cars and trucks! But the issue is with these the firewalls are not insulated!!! so we feel it

  48. Your probably picking up the heat that the Radiator Fan is throwing at the dash. There is a guy in Mississippi that makes a Radiator deflector shield that mounts to the back of the Radiator and deflects the heat down to the ground. I installed one on my machine and it does help a lot with the heat. The shield is also hinged so that in the winter time you can lift up on the door and now you have the heat coming back to the firewall to help with warmth in the cab. The only thing I can’t tell you yet is how much dust is the shield going to kick up while on the trail. I’m scheduled for another trip to the Hatfield And McCoy trails in October and will find out then.
