Hi Tilly

Apologises if you know this lot but here are a few basics to check.

1) Does the same thing happen in every gear (you should be able to get it going with no load at least in 4th - we used to do this on our engine dyno)

2) Does the noise continue all the way until the clutch is out? Does it do it with the clutch fully out?

3) What oil are you using - you must use motorbike oil, car oil contains extra slip additives that wet clutches don't like.

4) Have you taken the clutch out? Normally, when replacing the final plate in a pack it need to be 1 notch out from all the rest which I'm told is for anti-judder. Have you changed the clutch springs?

5) Can you take the spark plugs out of the engine, put it in gear with the clutch engaged, then turn the engine over using the prop - do you hear any grinding noises? Try this at different clutch engagements and gears.

6) In neutral, if you rev the engine do you get any noises with the clutch in/out. You should hear a change in the note and possibly a rattle, but no grinding/metallic noises

Let us know how you get on.
