On the handlebar, screw the small cable adjuster lal the way in.
Loosen the clutch adjuster lock bolt on the side (sprocket) cover.
Pull in the clutch lever all the way - you should see the adjuster turn on the cover.
With a large screwdriver, turn the adjuster clockwise, maintaining a slight pressure on the clutch lever.
As you turn the adjuster, you'll feel the clutch lever being pulled back out.
Turn the adjuster till the clutch lever is almost, but not quite all the way out. The finish pint is a matter of preference - some folks like a real "tight" clutch, others like a bit more "slop".
Tighten the locking bolt. You're done.
As the clutch cable stretches over time, you can make small adjustments at the handlebar adjuster.
