are you sure you did the clutch adjustment right?if you turn the screw the wrong way your clutch will not open up all the way,the best way to tell if you are adjusting it the write way is to turn the adjusting screw in one way a few turns ,then lift up your shift lever a little bit,you will notice that when you turn the adjusting screw in you will increase the slack on the shift lever,turn the screw the other way the slack will decrease.you want to decrease the slack on the shift lever,turn the adjuster counter clockwise until it stops then back it off 1\8 turn and tighten the lock nut.
