I have a 1997 Yamaha Timberwolf 250 2x4. A few weeks ago I was backing it off my trailer and putting it from reverse into forward and while doing so I heard a snap and the motor stalled. It is semi-auto transmission so I was at 1st gear and there is a lever on the side to change from forward to reverse. I tried to start it with both electric start and pull start and it just spins freely both ways. I think it is the starter clutch but I am not sure. Let me know if anyone here knows what it might be.
