And it was going so well....

After finally getting the old girl running smoothly, a rather unpleasant noise has developed. It sounds pretty nasty - really loud knocking noise coming from the guts of the engine. Above 3k it disappears, but under that - particularly tickover - it's feels like the engine is coming apart!! When slowly depressing the kick-start when the engine is off, it can be heard quite clearly. I've recorded the noise - it's not a brilliant recording - but perhaps someone with keen ears might be able to make a diagnosis. Hopefully not terminal!

Nasty noise!

I'm pretty certain it's your rotor coming lose :wink:

if it is, take it off and check the woodruff key before tightning it again :wink:

Here's my thoughts from best to worst;

Clutch idle gear bearing.
Clutch bearing.
Crank main bearing.

Hope it's one of the simpler options !! :shock:
Good luck.
