I took my 05 YFZ out for a ride on the crusty hard snow yesterday, and it worked like normal for about an hour of riding. I was on my way back to put in in the shed and when I got about 30' away from the shed, I shifted to first, and **** hit the fan. When I shifted to first, I heard a clunk noise and when I let the clutch out the engine stalled out. Now, I can shift through all the gears, but the bike wont move. I cannot roll it when it is in neutral either and it acts like it is in gear, but the engine will fire right up. It had the proper amount of AMSOIL synthetic 0w-40 in the engine(It is still very clean), so it wasn't a lack of oil. Any ideas???

 

yeh sounds like a tranny problem...dunno what, but just to let you know, i heard the synthetic oil makes yfz's clutches slip,...just to let ya know.

 

I got it worked out, shift fork broke and jammed in the gears. I dont have problems with the clutch slipping with the synthetic, now that I have heavy clutch springs, and the tranny shifts like butter with syn.
