Washed dirt and ice into the bearings? I'm not familiar with this machine but it sure sounds like something serious if you've gone into the clutch.

a tip I got from the dealer is the middle drive gear bearing is bad. the case needs to be split to rear it. just not worth it put 500 into a 500 atv.

does any body know if a 225 dx motor fit?

neighbor has the old tri moto at I could get chep
