Try this method and you should be good to go.
Here is an almost fool proof method for clutch adjustment. It takes the guesswork out of the "feel" for the adjuster.
Once you have opened up the derby cover and are ready to proceed. ALWAYS adjust the clutch on a COLD motor otherwise you could have shifting problems as the motor warms up.
1)Collapse the adjuster on the cable sleeve all the way.
2)Pull the lever against the bar and hold it there with light force.
3) After breaking the clutch lock nut loose,turn the pushrod adjuster bolt in with the allen wrench while holding the lever against the bar lightly until it starts to force the lever away for some distance. (Do this more than once to get the feel). While keeping light pressure on the lever back the adjuster bolt out just until the lever touches the bar again and then another little bit, about 1/2 turn , then tighten the lock nut in this position while holding the adjuster in place so it doesn't move. Easiest done with a "T" handle allen wrench.
4)Adjust the cable free play at the lever for 1/16"-1/8" free play and lock the lock nut on the adjuster. Slide the protective cover back over the adjuster.
You should be good to go .
