A couple o weeks ago my 4 month old heavy duty chain snapped under acceleration, looks like a small stone got in there. The chain bunched up under the front sprocket cover, smashed all but one o the bolt holes and knocked a hole in the gear change mech cover.... I'm pretty sure I managed to recover all the wee ally bits. Fixed the gear mech cover no problem, refitted, fresh oil so I could fire the engine to make sure it was ok. Engine fired no problem with no chain but there's a helluva nasty knocking sound coming from the clutch side and can be felt through the case and front sprocket. As the engine heats up the noise will go away but only with the clutch lever pulled in.
So I'm looking for ideas or notions o what I'm looking at here. Apart from the knocking noise the motor runs fine so whatever it is it doesn't seem to be interfering with the running.
My thoughts are possibly play in the countershaft which is normally taken up by load from having a chain fitted.
Cam chain tension out caused by the strain when the chain snapped.
A wayward bit o metal from the broken case.
Or a hundred other expensive things?
Depressed as hell at the thought of it being stuck in the garage instead of out on the road.....
HAYULP!
