I am having issues with my clutch and am looking for some advice.
Hardware: 78 Puch Maxi, Rito crank, Treatmetric Jammer Clutch.
Issue: Rear wheel is spinning while on stand, this also causes stalling at red lights sometimes. I can get the wheel to stop spinning by pushing hard on the case-side clutch lever. This confirms the starter plate is what is causing the wheel to spin. If I loosen the clutch cable the moped cannot be started.
Lower shim - 1.65 mm.
Upper shim - 1.82 mm.
Clutch face to starter plate clearance - 2.25 mm (spec is 0.3-0.5 mm)
Question: So I believe it is clear that my issue is with shimming, but I am not sure how to resolve. In order to get the clutch face clearance to spec I need to shim the clutch housing back by 1.75 mm. This is greater than my lower shim, which is the problem. How thin of a lower shim can I get away with? I see Treatland sells them down to 0.1 mm. can I really use a shim that thin alone, or is that intended to be part of a stack only?
I would really appreciate any advice,
Thank you! (edited)
