When you find your clutch arm is continually needing adjustment- and seems to be wanked way too far in to disengage- It may be a good idea to pull the 5 bolted clutch cover - and with a rubber mallet or the palm of your hand give the clutch face a sturdy thump! if it pushes in - pull off the small sprocket drive cover and make sure that nut is tight! This can shear your half moon (god forbid) at worse ruin your clutch shaft too. If the star washer is flattened do not reuse it. find another similar @ hardware store. This may be the only place where you would EVER use red locktite.
