1947 Rapide has had clutch working for years. Whole engine was rebuilt by Don Alexander (R.I.P.) and has done about 5000 miles since.
Problem now is the handlebar lever goes slack. This has happened over the last 2 months.
I have taken the clutch apart and rebuilt it (because of the problem) and made sure the drum is fastened securely. Everything has been checked and adjusted (both sides) so the operating arm, clutch rod, ball bearings, cable and set up is all working fine. Then off for a couple of mile ride approx and the handlebar
lever goes slack which eventually stops the pilot clutch working. This has now been done some 10 times with full adjustment after each slack off but ends up the same each time. The cable is fine the adjustments are fine, I am completely flummoxed as to what's causing the problem. I have tried pulling the handlebar lever without the engine running for some considerable time and it has no effect which tends to suggest its maybe a heat problem but I have not located any.
