Starts off in 1st just fine& 2nds ok but as I build speed and try to shift it starts the grinding noise, however, when I was riding I had to be speeding up or slowing down to keep a load on the drive shaft or it would make a racket. Couldnt just coast. Clutch lever feels ok.
I think it's ujoint or pinion cup.
Seems to be going around lately.
