How do you adjust the clutch cable on a 1986 Honda Shadow?

The quickest way is to adjust the clutch is at the clutch lever. You will notice where the clutch cable enters the top of the clutch lever. There are adjusting nuts there and two of them are longer and have a slit in the side. You loosen all nuts and align the two with the slit so that they form a straight line. Now you tighten the main adjusting nut until you can feel and see that as soon as you pull the clutch lever the wire inside the cable moves and the clutch begins to disengage. At this point you tighten the adjustment nut and disalign the two nuts with the slit. Fasten well. Drive the motorcycle around the block to see how the clutch works, then re-adjust if necessary. It is important that there is no marked dead play or slack in the clutch cable.
