Hello, i was taking the bike for a blow out when she stopped all of a sudden. its like when i try to start her there is a whirring noise. i checked the starter motor and its fine. its like there is a cog that isnt connecting to crank the bike up.

she had a new stator fitted and i checked the voltage and was constant.

Any advice would be much appreciated

starter clutch jammed I would say...dont know jot about them though...use the search function

I have similar symptoms on the the non starting bike I have just bought from a mate. It is being delivered on Tuesday and until I get the cover off to diagnose the fault I just don't know, could be the clutch, clutch rollers and springs or the idler and starter gear not meshing correctly. The bike turns over a couple of time and then clunk as the compression builds up. If the plugs are removed it turns over fine.

try this if you have the 535, other models have a starter bendix
