  2. Just to complete your post the most important thing on a batteries its de cca not in north america .after several test whit the replace of the oem batteries i never put the utv on charge anymore. Charging system cant support the OEM fan and starter (fan require 90 amp to run corectly minimum and start draw 180 amp to start perfectly) when you have lights on whit the fan starting on the oem batteries it draw too much amp than what the charging system can give (25 amp) . odes use the honda civic batterie for they're unit and it run really well. Just by doing the batteries upgrade,fans wont stay on for a long period 2 minutes max now. On my utv i got factory installed the second rad and fan upgrade and i not run anymore the secondary fan its useless. I have do the batteries upgrade on many nordik,hisun,motobishi and old cf moto curently and on 35 unit only 3 have still keep the over heat issue . most of them they not need to keep in charge when is at home . we see some difference on the performance aswell. . So doing this mod is a good move . the charging system are able to keep it charge because fan run less longer and the batterie have enough amp to respond to the request of the starter
  3. Against the brute it launch faster than my utv but around 65kph i close the gap and pass in front at around 100kph Against the renegade i stay behind but not by so much distances And against the Polaris on 27" tire it was neck and neck whit my utv until we Reach 30kph and leave it in the dust In deep mud my utv on OEM 25" tire have beated all ecxept the renegade but its okay i was pulled only one time for the entire day One of the 4 brute force got big electrical issue and 2 brake an axle in the marsh For a chinese product all guys as been quite impressed on the overall performance and reliability of it for the price
  4. If it can help you the vector 500 only need 1 batterie. But like any hisun fan,starter are an amp eater. The charging system cannot support all of that amp comsuption. Starrter and fan not enough whit the OEM batterie and the charging system. A good small batteries upgrade is a honda civic batteries. Enough cca for the starter and fan will run less too and faster. For parts is hisun directly
  5. So here the new i did the honda civic batteries to the system and it solve all trouble. Plenty of amp for starting,utv now stay between 12.5 and 14 volt while dual fan and light is on ,the honda civic batteries almost fit in the OEM batterie box but i prefered to keep the original one connected to the other batterie,i placed it in the back but when i have time i will make a new batterie box to put in 2 honda Civic batteries or just a 1095cca batteries at the Factory place. Fan now run less and really cool the coolant in the cooling system ,they have the required amperage to make it perform as it suposed to be . I have rewired the starter whit top quality wire and top quality connector so now it start quite fast(old wire was inside corrosion) The charging system work really well now they keep batterie between 12.4 and 13.3 volt when all electric is working instead of before so make this mod if you can. Something i noticed is that the exhaust system i not more glowing hard red when running what is quite really good because when the batteries come low due to the overcharge on the electrical system the performance was decreasing due to the lack of amperage and voltage to make good read from the sensor and keep the fuel pump running at the psi it supose to be running i am now able to race against against brute force 750 and renegade 800 on gravel road hehe 😁 and its a fully bone stock unit ,no mods at all ecxept batterie upgrade
  6. Personnally if you want bearing or seal go in a shop most of them can be buyed right there whit i.d. and o.d. diameter an other thing i hope you have checked all gear ,fork (teflon pad on fork too) ,and every sliding part i am an automotive thecnician and i have worked quite alot on t-case and manual trany and for make a gear pop out mean bad gear slider , a worn out bearing will make a noisy sound but for loose 4 and 5 im guessing that this trany have been beaten quite hard so maybe loose fork can be the next thing you will have to replace
  7. No problem at all but make sure every hose on the engine have a clamp on it (vaccum,pcv valve,also make sure the hole where the generator coil wire come out whit the crank sensor wire are siliconed. You will notice probally a 5% engine performance lost due to the snorkel (same story for a car engine snorkeled) but its not a big deal
  8. Anyway if they cant help me ill help myself out hehe. Curently a good batteries replacement for many chinesse utv is the honda Civic batteries. Take not so much space and its lighter . But if you plan on upgrade for better why we cannot put a bigger one if we. Have the space to and if the electrical system can hold hehe
  9. After 45 minutes of waiting i ended the call lol
  10. The generator coil is pretty good ,the starter itself need 2 time the amp of the batteries to make it work just fine. I can confirm you that the starter itself will never frie as long as you not try to jump start it whit a 24 volt batteries hehe and its a 12 volt starter its more damagable for the starter to run whit not enough amp than more(he cant take more amp than it need himself)maybe the power cable of the starter will have to be upgraded but not a big deal to this side. My biggest concern was about all the rest . Do the voltage regulator will like to have a batteries of 800 + cca. The whole system itself will be able to handle that? I tried to contact hisun but after 1 month they will never answer me hehe I know alot in the automotive but not so much in utv and atv so any good answer are welcome
  11. Its a bit late but it was caused by the drive belt clutch system
  12. Hi i am new to the utv world (i am an automotive thech in off-road performance on jeep and Dodge for 13 years that have decided to retire from the 4x4 world and play whit something smaller ) The big problems i see whit the hisun is a cooling fan issue that eat so much amp that the generator cant keep the batteries charge (i have the dual cooling system and whit 2 fans on it goes under 10 volts if you run at low speed that cause after few hours to run out of batteries. Batteries not have the amp to hold enough charge to push the fan at the best performance and generator cannot hold the OEM fan when the batteries is not enough charged (overheat issue was caused by that) an other problem that is a batteries issue was the starter itself it need more amp than the batteries have so the slow crancking is caused by that. When i worked on cf moto and odess utv i noticed that cf moto add the same starting issues due to the same problem too small batteries but odess use a honda civic batteries to make it work just fine (fans runs no more than 2 minutes instead of cf moto and hisun that the fans runs mostly all of the time) so i know that the batteries is a 12 volt u1 or u11 batteries so if i want to put a 1095cca batteries or a yellow top optima batteries on a custom case does the elictrical system will be able to handle a batteries that have 300-400% more ca than the small batteries or not (i know that the light will be more brighter i already replace the flasher/stop bulb factory instaled for a full l.e.d. bulb and socket hehe ). I know some people have done that on old 6 volt system atv whit no problem at all but i just want to make sure i will not frie the whole electrical system whit a bigger batteries hehe i will place some maxi fuse on the main relais and fuse system but not on the starter
  13. Its a timing chain guys not a belt . Your engine is out of sync stop starting it you will bent a valve (its not a valve free clearence engine) They have timing mark hole on the engine . Just go on youtube they have a tons of video that will explain you better than the shop manual how to replace the timing chain at the right place . Maybe when you do that you could check whit mr. Rpm for the stage 2 brp Cam upgrade the engine is entirely a brp engine built cheaper ( lot of odess ,cf moto and hisun owners replace this engine for the brp engine whit ecu
  14. Hi i have read your stories and i own a motobishi raptorex 2011 800cc (hisun strike differently named) Hisun brand its part of the ghanzou automotive that own cfmoto,odess, hisun and few other brand of utv. Check at cfmoto dealer for part. All driveline parts will fit on the hisun. It is what i have do on mine before it break and i never touched it again. The problem whit the yoke on hisun utv is a cast material and machining issue. If you are good in mechanic you can flip the coin and do brp, shaft and yoke upgrade (just need a good drive shaft shop to make new drive shaft
