Hi, clutch adjustment for the TS/TC125 & RV125 1964 to 1976 as follows:
1) remove magneto cover. 2) Loosen locknut, then turn in the adjustment screw until it seats lightly. 3) Back out adjustment screw 1/4 turn and tighten locknut. 4) Loosen clutch cable locknut, (here my picture shows this adjuster to be the one on the engine case) 6)Turn cable adjuster as required to provide 4mm play at the clutch lever,(picture shows a 4mm gap near the cable- nipple end, when you pull the lever) then tighten locknut. Hope thats some help.
