RE. DESIGN FAULT . - THE PROBLEM WITH THE GEARS IS THAT WHEN THE CLUTCH CASE IS REMOVED THE SHAFT PULLS OUT WITH IT ALONG WITH THE TWO RATCHET GEARS + 2 WASHER /SHIMS .THESE ARE THEN OFTEN ASSEMBLED INCORRECTLEY LEADING TO THE KICKSTART GEARS BEING MISSALIGNED AND NOT MAKING FULL CONTACT WITH EACHOTHER , LEADING TO GEAR TEETH BENDING + EVENTUALLY SNAPPING BITS OFF . EVERY BIKE I HAVE WORKED ON WITH CORRECTLY SPACED GEARS HAVE HAD NO PROBS . AND ALL DAMAGED GEARS WERE BECAUSE OF INCORRECT SPACING ON REASSEMBLY .

MONT/HONDA 200 + COTA 200 KICKSTART GEARS ARE THE SAME THRU 1980 - 1984 . ONLY CHANGED FOR 242/304/307/309/310 ALONG WITH KICKSTART SHAFT + KICKSTART LEVER . STILL AVAILABLE NEW FROM SPAIN + FRANCE

JUST SEEN YOUR OTHER POST , FILL USING 5W OIL IN DAMPER SIDE ( ONLY ) FIRST IF NO DAMPING DRAIN + TRY 20W + PUT 5W IN SPRING SIDE

IN 93 HAND BOOK IT SAYS 260cc BOTH LEGS ,BUT MENTIONS 2 X DIFFERENT GRADES OF OIL 5W + 20W . WOULD THINK 5W FOR DAMPER 20W FOR SPRING SIDE IF THESE RUN SPRING IN ONE SIDE ONLY . IF DAMPER RODS IN BOTH FORKS USE 5W IN EACH .
