Yep the starter clutch was shot and the 3 allen bolts holding it together were stripped out and the whole thing was loose and falling apart. You need a special socket to remove the nut holding the clutch on. I didn't realize until it was too late that the nut was a left hand thread. I either stripped out that nut or the crankshaft 🙁

Turns out the issue was much easier than I expected. The rubber piece was ripped nearly all the way off on the intake manifold boot. New one off amazon for about 10 bucks fixed it and it's got plenty of power now. Still a project that needs brakes and tires and some carb adjustment but I think the main issue is fixed for now

Looks like I need a new starter clutch. Got it torn apart and will order a new one tonight. Will update if I get it fixed

Pulled the new starter back off to check out the gear it spins and that little gear is in fine shape. Obviously something else is stripped out but I'm not sure what.

Hey all, I just picked up this Massimo UTV for $500. Got it home and replaced the starter solenoid which successfully got power to the starter. Starter spun but engine didn't turn over although the engine is not locked up. I thought it was a bad starter. Got a new starter put on today and it does the same thing. Pulled the clutch cover and saw the engine is trying to turn over but something is slipping and not letting it turn over. I figured it must be the gear on the engine that the starter turns. Where can I get that and can it be replaced without pulling the motor? And am I correct that that's the issue? Thanks! Short video attached below

Sorry to disappear on everyone after asking for help. I haven't had much time to work on it at all and have been tied up with other projects. I did get it back together and hope to mess with it more soon and will report back when I do. Thanks to everyone who chimed in

Will do that when I get home Sunday. Thanks everyone for chiming in It isn’t a wiring short, it sounds like the bike is stopping and forcing the engine to stop as well. Once I get back in neutral it fires right back up. it’s hard to describe. Maybe Sunday when I get home I can put the rear end back in and try to get a video of it happening. It acts as if it’s bogging down because of too much load. I haven’t personally shifted it through the gears on jackstands but I was able to drive it from the front to the back yard in first gear just fine while walking alongside it. But then when I got on it and tried to drive it, it tries to go but acts forced to shut off. The neighbor I bought it from said when it worked he was able to go through all the gears without an issue and didn’t think it was a clutch problem.

No it's stalling out the engine like if something is locking it up and keeping it from turning.

Hi everyone, I’m new here and new to 4 wheelers. Just got a Yamaha bear tracker 250 and joined here to see if I could get some help. The motor runs and it drives if it up on jackstands but if you get on and try to ride it, it starts to drive but then quits after a foot or two and dies out and won’t drive. The guy I got it from said he was running and using it shifting through all the gears great and he started it up the next day and it started this. He told me he thought it was the U joint on the driveshaft. He said it was probably worn and needed to be replaced. I just finished pulling the swing arm and rear end assembly to check out the U joint and there’s no play in it. It’s tight and not nearly enough play to be loose enough to not catch and go. Any ideas on what it could actually be? Thanks Timothy
