So i have finally finished the 2000 lt80 and got it running. It doesnt want to move. The engine slowly revs but the atv barely moves, i have to give it a push and then it goes. Once its moving it goes down the road ok. Top speed is pretty good, and accelerating from mid speed to top speed is good. But once stopped it doesnt want to move again. It moves easier on the ashphalt road way better than the grass. Is this a thin belt or a stuck clutch? Is it the front clutch or the rear clutch. Where do i start?

 

I'd inspect both front and rear altho the front is prolly where the issue is.
FYI: the belt shouldn't be the problem but you never know till you look.
