How do you adjust a clutch on a 89 Yamaha blaster 4 wheeler?

To adjust the clutch on a 1989 Yamaha Blaster, first locate the clutch cable adjuster near the handlebars. Loosen the lock nut and turn the adjuster to achieve the desired free play; typically, there should be about 1-2 mm of play at the lever. After adjusting, tighten the lock nut and check the clutch engagement by pulling the lever and observing if the bike shifts smoothly. If further adjustment is needed, you may need to adjust the clutch assembly itself, which involves removing the side cover.
