Trouble with bike

<< < (10/19) > >>

Oddjob:
Yes Phil, it sounds like a very loose primary, loading it up with the clutch will make the noise either go away totally or at least lessen it.

beardylondon:
Thanks again, doesn’t sound like an easy or cheap fix?

Oddjob:
If it is, then it's an engine out job, about £50 or so for the chain and another £30 odd for the damper rubbers. After that might need a few gaskets, oil and such.

Sesman:
Might be worth dropping the sump for a visual too? That will seal the deal if loading the drive changes the noise being generated.

K2-K6:
I can't see or hear the clip to judge.

But, are you sure it's running on all four cylinder competently  ? If its not, then they sound poor, and that will definitely flick the chains around too.

Basic check is to start it, then stop after 30 sec, to now check the exhaust headers with your thumb looking for a cold one. If any are cool/cold you'd need to look at that cylinder again to get all running well.
