Posted by: David TITLE: MOTORIZED BICYCLES:   Squealing when riding
Thanks for the help on my previous clutch problem, I now have another... I got my motor working but when the clutch is engaged it feels like there is something grinding. The is also a sort of screaming noise. I have greased everything in sight, and ensured that the clutch nut is extreamly tight so that is does not slip. I don~t really know what else to do. The squealing only occurs when the engine is running and the clutch is engaged, I can give gas to the engine while the clutch is disengaged without any squealing.
Thanks again for your help

Try a brake cleaner spray, if this does not work to your satisfaction, try simpsonmotorbikes.com for parts. Mr. Simpson is very knowledgeable and active in motorbiking.

It is a 60cc Grubee Skyhawk, how can I change the friction material in the clutch? Could I buy a standard friction plate and cut it to size? Has anybody had any experience with changing the clutch on a grubee type engine? I ll give cleaning a shot, but I think the clutch might be too far gone as is.
Thanks for your reply,
David

What sort of machine are we dealing with here? The only Whizzer I~ve ever seen in opperation, squalled every time the belt was engaged. I not sure if this is typical, if this is a china engine picostarhawkfire sqealing is very unusual and would probably mean the some grease has found its way onto the clutch surface, which would be terminal for the clutch, although I personally would attempt something unorthodox like spraying the dissasembled clutch w/ brake cleaner and knock off the glaze w/ a light sand paper.
