i have a 1995 rm 125. when ever i pull in the clutch with it in gear when not running it dosen't disengage the clutch from the transmission. and when running when i shift into first it jumps and stalls. now i adjusted the cable right and everything. but i took it apart and the plates don't look to bad but the basket and inner hub have very deep grooves in it. is this what is causing my problem and do i just need to replace the clutch plates and springs along with a new basket and inner hub and it will not does this anymore?
