How do you adjust the clutch on your 1992 Suzuki RM80?

On the right side of the bike, follow the cable down to where the clutch case is. On top of this case, the cable enters into the clutch case. Right here there will be an adjuster, turn the one on the handle all the way in. Use the adjuster on the clutch case to get a rough estimate and then use the top adjustment to fine tune it.
