love the forum. We just got a mostly rebuilt Hisun 2009, runs great, no electrical issues yet, however notice a grind and clunk after accelerating and stopping, such as at a stop sign. Sounds like wire caught underneath. We looked it over and only thing that comes close to being in the area is the secondary clutch. Some wear and play noted there. Will replace, but not sure if we are going to fix the problem.

Wasn't sure exactly how to title this thread as I have a few issues with my newly acquired hisun UTV. Hopefully going to consolidate all the issues in one thread.
I purchased from a guy who had rebuilt the engine replaced the fuel pump as well as re-done the front end. He had the unit running and driving when it quit and would not start. He got frustrated and decided no more projects and sold it to me. Unit is in excellent condition physically.....hardly any scratches on the plastics. All in all its a good unit with the following issues/symptoms
1) Mis fire and stalling out when revved
Well as you can see by the title of the first issue I managed to get the unit running. Seems that the battery was very weak. I charged the unit and it fired up fine. The engine seems to stutter and misfire when revved and once the unit warms up it stalls out. I think it's a fuel issue as if I give it a shot of ether it starts back up.
Additional Note: Revving engine in Neutral seems to cause indication to flicker and occasionally the reverse light comes on which seems to kick in the reverse rev limiter. Have also hade this happen when driving around. Reverse Light flickers and revs get cut.
2) Fuel line configuration.
When he replaced the fuel pump he got creative with the tubing and removed the "small fuel tank"
Not sure what the purpose of this tank is but would love some pictures of a stock set up so I can put everything back together correct.
3) Issues engaging in gear
The unit seems to have issues going in to gear...I will move the shifter in place but the gear won't engage and the lights don't indicate correct. It takes a few tries to engage and sometimes it grinds a bit
4) Rack and pinion slipping
This problem is probably a simple replacement fix...when turning to the right with the vehicle not moving the steering just slipps and turns without turning the tire. I believe I just need to replace the rack and pinion but if there is something else please let me know.
Any insight or tips on resolving any of these issues would be much appreciated.
2009 Hisun 700. Well, back to square one. I've been doing this rebuild since Jan. 2021. MANY new parts and fixes and re-starts and working/then broke/then working/then broke... and on and on. Last week I had a good ride, about 18 miles. Ran great. Parked in the garage for 2 days and then the exact same problem as last time-- Cranks and cranks, about 6 or 8 times, and then click: nothing. I get one click and a red warning light on the dash but it's too small and doesn't say what it is. It's not the battery: it's fully charged. Had it on a charger overnight afterward and still getting one click. It's like the starter is stuck or the engine is seized. The last time it happened I took it to a guy who's rebuilt many of these and he found the starter was full of oil! Black oil. He said it was black 'cause it got cooked trying to crank. Put in a new starter and he did all kinds of adjustments and between him and the neighbor it was running great. Now it's stuck again. I'll pull the starter when I calm down.... One of the MANY new parts we threw at it was a new battery. it's got plenty of power, 350 cold cranking amps. Is it possible to have TOO heavy a battery? But has ANYONE run into this?
