1994 xr600r I have seepage around the 2 round chrome domes with hex counter sunk on head cover, just above the RFVD? letters.(2 on each side of head cover) are those just covers for the rocker shafts or the actual shaft. In parts fiche, looks like shaft & no seal but a washer. Should I crank down tighter? Is there a simple fix? ALSO I have a leak where the clutch arm enters left side cover. I see seal in parts break down, but cant see what holds the arm in place? Looks like I should be able to pull out arm without taking side cover off. Anyone have experiance in this area. I know one person previously said I must take off side cover , but I cant see why. Also is it a good idea to change out bearing or is it a bushing? (if I must take off side cover) Thanks in advance!
