Bought my '81 Interstate in the fall of 1989. I'd only ever adjusted the clutch at the hand lever. I've pretty much maxxed that out, so I pulled out the service manual and read the very straight forward clutch adjustment procedure. It sure would be easier with the engine out of the bike! there's a cross member of the frame right at the clutch basket. Did the best I could by feel. Is there a special tool that allows you to hold the threaded rod while tightening the lock nut down the recess? Thanx, Dave
