Adjusting the clutch cable

The cable is adjusted by checking the amount of freeplay at the clutch lever. First, adjust the cable at the handlebar end so it's about in the middle of its adjustment, then use the two nuts down near the engine to set the initial free play. That way there is plenty of movement in either direction at the handlebar end for later adjustment. The lower adjusting nuts are on the right side of the engine, near the oil sight glass.

To adjust freeplay:

1) Loosen the locknut at the clutch lever. 2) Turn the adjuster so that the clutch lever will have the specified free play (2-3mm). 3) Tighten the locknut. 4) If your cable has stretched so much that you can't adjust it at the lever, loosen the bar adjusters and take some of the slack out by tightening the lower adjusting nuts.

Alternative adjustment method

Wes doesn't measure the free play distance, but likes it to engage when the lever is about 1 inch away from the handlebar. That way there is enough movement that it doesn't creep when the lever is pulled all the way in, but it moves when the lever is released. He does it that way to try to prevent fatigue in his clutch hand. It doesn't seem to cause excessive wear on the clutch plates.

The book says 2-3mm slack in the cable. Wes leaves about 15mm because he doesn't like the stock lever throw. This has the side effect of rattling like hell, though.

The key: you need SOME slack to make sure the clutch engages fully. You also need to make sure the clutch disengages fully when the lever is at the bar. You can tell if this is the case or not by listening to the pitch of the engine as you shift from neutral to 1st with the clutch in on a hot motor. It should NOT change.

As long as those two points are met, it doesn't really matter what you do. It's all personal preference.
