Instead, I try to set the clutch arm so that it's just at the perpendicular relative to the clutch pushrod when the clutch becomes disengaged. I use the bolt in the arm to make this setting. This gives the maximum leverage against the clutch spring and the lightest feel.
Then I adjust the cable at the handlebar to get a 1/4" or so of free play between the lever and the perch. You need some free play or the clutch will always be slightly loaded, wearing it out sooner and making it hot and grabby.
My owner's manual doesn't mention much about the adjustment at the back of the transmission. It just mentions the values 0.24-0.32 inches at the hand lever.
I've read on the Airheads list where the approach is to focus on the free play at the handlebar lever using the adjuster up there to have exactly 201mm of cable sticking past the boss in the lower right side of the transmission. Once that dimension is set, then the cable is attached to the arm at the back of the tranny and the adjuster/locknut at the back of the tranny is adjusted until there is 2-4mm of free play at the handlebar lever...the distance between the lever and the control base.
Is there some distance like that for the /2, ie, 201mm? What approach do others use to set the clutch free play?
