when kx is running clutch gear selector rattles back and forward when in neutral,or in gear, when clutch is pulled it stops,but it restarts when gear is selected and clutch released, i can hear sort of grinding noise from clutch[sounds like kickstart is still half-kicked but its not] when riding bike clutch slips after about mid revs, problem just started during riding, i have checked cable, seems fine and adjustment seems okay, any idea's
