Clutch adjustment is fairly easy, disconnect the cable, lay the bike on its side and remove the clutch cover. Do not take of the shifter or kickstarter, they will come off with the cover. In the middle of the clutch hub is a 10mm nut with an allen screw in the middle of it. This nut will need to be loosened, to do this there is a small hole next to it that needs an allen wrench put in to it to stop the nut from turning, use one a few sizes larger than the one you will need for the allen screw. With the nut loosened and with the allen wrench still in the lockout hole tighten the middle allen screw until you get about 1/4 inch play in the lever on the case. tighten the nut remove the allen wrench you used for a lockout and reasemble making sure the shift lever lines up when you replace the case.
Kind of long winded and probably confusing explanation, but it is relatively easy 5min job
Hope it helps
