    250cc performance exhaust

    for those of you who havent been to our site yet, here is a look at our performance exhaust system. Made in house, certified for spark arrester, and db rated at below 94db. Legal for any race track, trail or off road park. Great sound without sounding like an open pipe as with some others out there. True bolt on kit.

    250cc longer wheel studs

    Hey there folks, we are now stocking longer and stronger wheel studs for the 2500cc line up, including models from Coleman, HiSUN, Benchee, Massimo and others that share the same parts. The fronts are pretty easy to change out as the hubs are aluminum, but the rears are a little harder since they are made from steel. Really helps with different rims, racing, or striped out poor quality OEM versioins. These are rated at 10.9
  4. You could also apply some grease or lube to the post to assist it from sticking

    Slow 2017 HiSun Strike 250

    No problem, call me if you have any problems. Here's a pic of what you might come across. The fuel tank will have two connectors, one is for the fuel pump and the other is for the fuel tank sending unit. You will know when you test it which one it is. But by lifting on the plastic float, you will see the Ohm meter rise and fall. Or it might just be stuck or sticking on something? Moving it by hand might fix it. who knows..................

    Here is a great video showing how to test any fuel tank sending unit. Pretty simple, don't worry about the color of the wires in the video, but the process is the same.

    The fuel tank sending unit is not to hard to locate. it should be under the seat area. There should be a connector that takes the signal from the sending unit to the gauge. Check to make sure the connector is properly connected first. Then you can measure the resistance from the connector. It would be helpful to have the fuel tank sending unit out of the fuel tank. It is part of the fuel pump assembly. Remove the plastic ring securing it in the fuel tank. Pull it up and out easy, Now you can slowly push up on the fuel tank sending unit and watch the gauge to make sure it responds correctly. If not, then measure the resistance in the wiring. If it does not meet the OEM specifications, then the sending unit is faulty. If it is good, then you will need to check the connections to the gauge. If everything is good at this point, and you are getting the correct signal all the way to the gauge, then the gauge is faulty.

    I have a question about your HS400. when you are driving it, do you have the seat belt connected? Just wondering because it can effect the speed limit. I would go to the back of the seat belt connection located when you lift the bed up, you will see the light grey connector. Unplug the electronic connector for the seat belt and try it again. See what happens.

    I wanted to spill the beans sort of with some exciting news! Next year there is a national event that will be televised that will have youth UTV racing with only HiSUN Strike 250's. I am working with HiSUN and another group to get this off the ground. We are working out the details now, but it should be exciting to watch HiSUN Strike 250's tear up the track, racing along side other HiSUN 250's. I can't say much more now, but when allowed, I will tell you folks more about it in the coming months. I was lucky enough to be chosen as the supplier of race parts for this event. They will also be using the new HiSUN Strike 550 and the Strike 1000. So three classes next year should be a great year.

    I have a lot of contacts at HiSUN, and we work together to help everyone out there with questions. Remember, I am not employed by HiSUN, but rather a person that started out just like you, buying one of these units and looking for help. If I don't have the answer, I will get it.

    This is something I do for the folks out here on the westcoast that race these units. They want all the speed they can get. I do change out the transmission gears as well as rear sprockets, ECU tuning, and of course our exhaust system.

    I can get the 2015 ECU, but its pretty easy to just send me yours and I will re-flash it for you. I normally charge up to $100 for this, as a new ECU is about $344.00. You would only need to purchase a new ECU if you wanted a stock one and a modified one to exchange. I will do it for $80.00 for any customers from this site.

    I have a guy I use that is an authorized HiSUN parts supplier. You can get him at: [email protected] Let him know you hear of him from 250UTV.com and he will take care of you. He also does a great price for my customers.

    On our 2015 unit we use for R&D, I think we have had the RPM close to 8750. But I am not sure how reliable the gauge is in the dash. We are doing some dyno testing currently. I will check the dyno for a good readout. I am not sure about going to a 38 in the rear with the newer internal gearing, but with our ECU flash and a 40 rear tooth, it should help a lot. We are now selling rear sprockets that are split. This allows you to change the rear sprockets in the rear without removing the entire axle assembly. The new split sprockets will be up on the site by monday. But we do offer a new re-flash on the ECU. Just send in yours and we will re-flash it, or unlock it as it is sometimes called. Keep in mind, with many rear sprocket changes, you might end up having to remove a link in the chain if you go to small in the rear due to the limits of the chain adjuster slot. We are also offering updated chain adjusters, easier to adjust than the OEM version.

    The old parts numbers for the pre-2016 250's internal transmission are: MAIN SHAFT P013000222010000 $75.00 (OLD PART #) MAIN SHAFT P013000222010200 $75.00 (NEW PART #) OUTPUT SHAFT 22300-013A-0000 $140.00 (OLD SHAFT) OUTPUT SHAFT 22300-013-0000 $140.00 (NEW SHAFT) COUNTER SHAFT 22220-013-0000 $105.50 (OLD SHAFT) COUNTER SHAFT 22220-013-0001 $105.50 (NEW SHAFT)

    There is no change to the clutch assembly, both the primary and secondary clutch assemblies are the same in all years. They changed the gearing on the shafts in the transmission which has a direct relation to the output shaft speed. This along with the rear gearing and the modified ECU, keep the 250 at a to speed of about 32 is mph. It also controls the RPM so that the clutch wont engage all the way. I am able to open up the ECU through software programming. Also I have sprockets for the rear to allow a better top end speed. But to change everything back to the pre 2016 version, you would have to split the cases, and change the three shafts inside the transmission. This is not a realistic option for most. So, with the ECU opened up and set to pre-2016 flash, and the rear sprocket at about a 40 tooth, it seems to help a lot. You will get a higher top end but still keeping the off the line speed most of us enjoy. I call it a compromise.

    Wow, what great questions. I will do my best to answer them. First off you had asked about the EFI Delphi MT05 module has been altered since 2017. they did change things to slow down the UTV per customers complaints that it was going too fast. So, being the large company HiSUN is, they wanted to avoid any litigation in court and damages. They altered the vehicle in question to slow it down. They did this by doing a couple of things, one of them was to change the mapping in the ECU to control the top RPM limits. Second was to change the gearing. This was done in two ways, first was changing the final gear ratio from 11 front sprocket and 38 rear sprocket, to a 11 front sprocket and a 42 rear sprocket. The second thing was to change the internal gearing. They changed the main shaft in the transmission, the output shaft and the counter shaft. They all have gears that when changed with the final gear ratio helps keep the unit down on top end speed.

    Here are a couple of pics of our new Trailer Hitch for the Sector 250. And no, it doesnt hit the chain when the unit is compressed lol. It bolts on, is powder coated and attaches to the units frame. It has a standard small 1 1/4 inch receiver.

    hisun strike 250

    Hey there, new member here, just looking for information and tips. I just purchased a Hisun strike 250 for my young son. We have taken it to elsinore mx park here in so cal and he had a blast. I know I am going to get a lot of feedback regarding this, but I have to tell you, for the money, and his age, I can't complain. It always starts, is a blast to ride, and yes, I can fit in it at 6.1 and 195lbs. Have we had any issues? sure, but about the same about as any other vehicle, so I can't really complain. We couldnt find any aftermarket parts for it, so we engineered our own 2 inch lift kit for it, and it worked great. We have mounted additional lights on it as well. Some of the things we did notice are that the shift linkage seemed to be rubbing the exhaust pipe, and so I modified the shift linkage, and now that problem is gone. I also noticed that the factory plastic is very brittle, meaning it will crack if not handled properly. The quality of the OEM nuts and bolts are very poor, they seem to strip out very easy. So, we are replacing what ever bolt we remove, with a higher quality version. The battery is not easy to access, and in a pinch, that could be a problem, as tools are required to get to the battery. If you were to need a jump out in the boonies, you might be stuck. Also, the factory 4 point harness is hard to adjust, so we might have to replace them with aftermarket versions. Aside from that, he has not really had any problems with it. Granted it is not a larger 500 or 900cc UTV, so the load and demands on it are less. I do wish it had more power, but since he's only 9, I am good for now lol. It never quit on us, ran great in 106 degree heat, and handled the muddy track with ease. Another plus, it fits in the back of my truck bed with the tailgate up lol. Just my 2 cents.

    Hisun Sector/Vector 250 Service Manual?

    The only real difference is the plastic. Otherwise the vehicle is pretty much the same. The engine, suspension, electronics and all are all the same as the Strike 250. The only difference is the shift linkage, and the rear body. Even the OEM service manual is not 100% accurate either, so if you have any questions, please feel free to just ask and I will do my best.

    Don't forget about the new exhaust pipe
  25. Well, we have finally finished our new exhaust system for the Strike and Sector 250. It bolts right on, weighs 6.2 lbs lighter than the OEM muffler assembly. It is rated for no more than 94db for trail and track regulations. It also sounds and works amazing. We have priced it out at $299.99, far below anyone else making a system for these units because we want to give those who have been waiting a while for them a price break. It is also spark arrester approved.
