Hi I'm about to order parts to do a bunch of work on my Massimo. Does anyone know if there's a difference in the top end kit {piston, Cylinder, Rings, Gaskets, Piston Pin} if it has a carb or EFI? I'm EFI and I think some came with a carb so I thought i'd ask before making a mistake...
Thanks Jerr

hi everyone i have this 2021 Hisun forge 250 that won't start. no spark no fuel. when i turn the key on i dont hear the relays click or fuel pump come on. it does have power but the relay doesnt ground the pump or the ignition coil. dont know if there are any safety switches on this model or not. it does crank and all the accessories work. i hot wired the pump and it does work. i found a wiring diagram but it's very hard to figure out and was hoping someone has seen this before. all fuses are good. thanks in advance.

Hello, I have a 2013 500 utv hisun. Was running ok and cut out while parked. Bike will not start now. It turns over, but won't fire. I have no spark and no fuel. I replaced fuel pump, ignition coil, spark plug, cdi, voltage rectifier and all the fuses and relays. Could bad stater cause no fuel because I can't hear the fuel pump priming. Any info on where to start looking for problem.

I recently purchased a 2024 Hisun 550 Sector from Kreps Service Station and am having issues with the gear selector, I am doing as instructed in the owners manual but the shifter acts like it is binding or the button lock isn't releasing, the shifter will not move, I have to wiggle it back and forth while pushing hard on the brake and if it's in park or reverse it's nearly impossible to get it to move, I contacted Justin Krep and he says this is normal with these machines, I find that hard to believe, I've owned many utvs and side x sides and have never had this kind of issue with any of them, any help with this problem would be greatly appreciated.

As I tried to do a conversion with the Yamaha 660 motor, I realized the 660 was never fuel injected so it would not work for the fuel injected hisun motor swap. But the good thing is the hisun 750 motor is a clone of the 660 Yamaha but with the components for the fuel injection (cam/crank position sensor). So that left me with a new rebuilt Yamaha 660 and still a broke 750 hisun motor. I took apart 750 think the timing chain had broke from all that I've heard about these motors. The chain was not broke, but just off cam and crank gears! The chain tensioner was at fault! I've ordered Yamaha 660 replacement parts, chain, two exhaust valves (which got bent when chain came off while motor was spinning) and seals. The piston has 2 little nicks where it had hit valves but no damage otherwise. The head is being redone at the machine shop and I'll be putting it back together in the next couple of weeks. Also I finally tracked down a Service Manual with all the info on the 550/750 Challenger.
