thanks.. pretty simple eh? good to know ....but  I laughed at the part..." THIS VOIDS WARRENTY"   lol  like HISUN has a warrenty.....lololol

same here.. it seems to be some kind of safety feature , not allowing fast reverse .. dont know how you would bypass it . let me know if you find a way 

My MSU 500 does not rev up  in reverse. either . so it must be a limit in reverse only 

wouldnt running that much  oil OVERFULL in a small engine like this  cause oil  leaks and oil burning ? That level  increases pressure in crankcase, and excessive oil  being slung by crank into cylinder walls and reduced power because of the drag on crank ....just sayin

We found that bypassing the thermal switch on radiator to make fan run continuously when key is on, ended the overheating.....of course  thats after we replaced the head gasket, then the warped burnt  head and  gasket again.. in beginning on hot day, it would overheat in 1-2 miles.... We tested their settings for switch. The fan engaged at 238 degrees if I remember correctly .. and the switch is on the COLD  side!!!  how hot was the engine ??? 250* -260*??  The heat in the cab was unbearable, I would be drenched in sweat in minutes.   .. now with a new adjustable switch and engine staying 150*-160* , the cab is pleasant..  I would also Check yours to see if head gasket is fried. look for air bubbles in recovery bottle while idling hot.  and / or water in oil.

Massimo sent me a new throttle assembly, injector and still has no power.  I’m getting very frustrated, wish I never bought.  Nobody in San Antonio Texas will touch it

Welcome to the very large  world of dis-satisfied Massimo owners.. I bought mine in 2017 . it broke on the first day.. To date, Massimo has never paid one dime for the many many repairs it needed.. only one shop will touch them in my state.. CASH ONLY up front!   Good luck........... BTW.. is that a Lhasa Apso in your pic?  looks just like mine that passed at 14 yrs old .. Loved that dog

I still say if manufacturer didnt want you to DRAIN the oil and wanted you to vaccuum it out thru the dipstick, they would not have installed a DRAIN PLUG!  just sayin

While I am the first one to blast HISUN and everyone involved with them  for poor quality and nonexistent warranty ....since I "hybridized" my Massimo with a bunch of  Yamaha parts, its managed to be a decent machine .. Altho I did pull out several handfuls of my remaining hair in the beginning

ouch

Yeah, I just bought a Coleman Outfitter UT400 from Tractor Supply and they told me about Coleman's Chapter 11, which I confirmed online. I contacted Coleman about parts and every time I call I get a different answer ... We are not shipping parts at this time ... we can ship within 7-10 work days ... we can ship, but you won't get your parts sooner than 3 weeks. Seriously, I might be returning my UTV and get a refund.

Trust me, you wont get a refund.. I bought my Massimo from Tractor Supply. in 2017 . It broke that same day with 001 mile on it.. They refused return and had no clue where to get it fixed.  And to this day, it has  been in shops 6 times in its first year, and neither Massimo or T.S. has paid a single dime if repairs .. But they generously gave me a $50 TS gift card!!! lol

most say 20-25 hours or 1 year.. not 1 month unless you never turn it off!    MAKE sure you use an oil approved for wet clutch........ DO NOT use automotive synthetic oil or your clutch will be toast 

I screwed up and bought a new 2017  Massimo MSU 500 from Tractor Supply because my elderly father cant ride a ATV anymore.  .. big mistake.. It was bad enough that it broke on its first day but Tractor Supply did not even know who serviced them!  As it turned out, NO ONE would!  Massimo did not back their warranty or pay claims.. so no shop would work on them  stay away from anything Massimo . or Hisun..   I have friends that have UTV Hondas and Kawasakis.. good machines.. I have 3 Honda ATVs.. great machines.. indestructible.  I  bought a 2023 CF MOTO 600 ATV  last October.. It is impressive and trouble free and 2 yr warranty instead of 1 yr like the rest.    but I do not know about their UTVs.. .. shop around .. Prices are high right now and inventories are low.. good luck.. Let us know what you buy  

  I bought new..... still spent 2 years in and out of shop... as for street legal, you need to check with your state DMV.. some do not allow Low Speed Vehicles ,  UTVs /Golf Carts ...... find out what the requirements are and the cost to comply, what safety equipment, how much liability insurance, which street tires etc.  .. they do not come "street legal"

so it was lean A/F mix condition ... glad you solved it 

 glowing red header usually means 1 of three things.. restricted exhaust pipe/muffler, very lean air/fuel mix or late ignition timing.. 

sometimes you gotta just say WTF!

I agree with you, Joe. If they made a filter that could remove all the dirt and other contaminants, we would have much greater oil change frequencies.

I have another  old friend who is an engine rebuilder by trade.. he says he changes just the filter at  5K, 7K, 10 K and 13K and then changes oil at 15K. because oil does not wear out , just gets dirty

Dude, it's got me flustered. The only thing I haven't done is replace the battery cables. Maybe I should try some cables that are larger in diameter?

I did put larger cables and a car battery on my mower.. still has to grunt 2-3 times before it spins fast enough to start..

Still running good. I still have the issue with starting. Just takes a few hits with the key to get it to turn over and start. It doesn't get run every day, though. Maybe that's the issue?

I have a Zero Turn 60 in mower that has done that for years.. I have replaced starter, battery, cables, switches , every part in the starting system and it still does it!.. crazy huh?

It's not important to get every drop of oil out of the engine during oil changes. You won't anyway regardless of method. That's why most modern brands use the quick method with oil extraction pumps. That will get all but an ounce of oil. If you got sludge in the engine oil, you have bigger problems than an oil change will fix. If you change your oil every six months and haven't abused the engine or have engine issues the extracted oil should be pretty clean. You're changing oil because it wears out and ages not because it gets dirty. 

I completely disagree.. You change oil BECAUSE it gets dirty and can no longer hold deposits in suspension.. Oil does not wear out in 3000 miles .   heres a thought from a real  expert..........." Does oil wrar out?  

..........oil  goes "bad" from two things:

1. The long chains get broken down due to wear. But ask any tribologist with an ounce of morals, and they will tell you that modern engine oil is sufficient to last MANY thousands of miles, perhaps 10-20K or more . (I get that you speak hours - I'm too lazy to translate that to knots.) And that's good old dinosaur juice. Modern synthetic compounds have wonderful properties, and might last twice as long as the organic stuff. In fact, with the exception of point #2, the right synthetic might last 50,000 -60,000 miles. (x 0.868976 knots)

2. and you say...BUT BUT BUT.... Oil gets dirty. Little particles of soot and combustion products and small insects and detris and debris and schmutz and water accumulate in your oil storage "area". A really good oil filter [e.g. Oberg] might filter down to 5 micron or less, but require frequent cleanings. Hence you only see this type of filter in racing and special applications.

   2A. So what? heres what!  Some of that dirt is abrasive. None of it is helpful. It is circulated under pressure. Now imagine that your very expensive synthetic oil is circulating little tiny abrasive bits all around those critical lubricated interface points. Doesn't matter how much the "excipient" [big word] costs, what you have now created is a very expensive  cutting fluid -. no matter how expensive. The size of the little cutter buggers is only limited by your oil filter. And your standard oil filter is a balance between longevity and particle size.

So So So?

Oil gets dirty. (Did I yell that yet?) YES AND OIL GETS DIRTY AT THE SAME RATE .. got it?  WHETHER IT'S USED "Wolfshead" OIL FILTERED THROUGH WONDERBREAD, OR ULTRA-SYNTHETIC  Magic elixure DERIVED FROM SIBERIAN ANT GLANDS AND COSTS $5000/ounce... It gets dirty long before it ever could wear out!  ""            

I happen to agree with that 100%

yep. trust the science as libs say.......Its GRAVITY!  cant deny it   Hows yours running?  my mix breed Massimo still going strong. 

not a fan of the quicky lube syphon method.. its fast and easy and saves time for  Quick Oil Change shops but I seriously doubt it removes all  the sludge in the bottom of the pan completely. or the metallic debris on mag plugs . The drain is the lowest point and everything will come out if engine is hot and you can clean the plug for fresh use. .  Trans shops now use similar methods of  quickie replacing fluid by machine with fresh fluid.. But you still have your old dirty filter inside trans and whatever sludge and debris are in the bottom of the pan.  .

Well, it wasn’t either of those, after tracing wires, cleaning every connector and adding dielectric grease, no bad wires and fuse was the first thing I checked/changed.  It was the relay, $45 on eBay and it’s now running again, with a much quieter fuel pump to boot!

good job... looks like you didnt need help after all 

if pump runs with direct 12v  and if you have no power at plug, its either a fuse or bad wire.. fuse box is on wall under hood 

that is true.. We have a Jeep with the 4.0L six .. it leaked from every gasket.. BUT, not until 180,000 miles.. after I replaced pan, rear seal ,timing and valve covers, no more leaks..  Whereas  HISUN leak on the boat from China . AND  If a car leaks on day one, the Dealer will fix it.. Hisun will never fix anything. Their warranty is written on toilet paper so you can at least use it to wipe your butt
