I thought you need to remove the clutch to access the stopper arm bolt?

No not at all, What stopper arm bolt??
On the claw you will see a stamped index line you will/should see a similar line on the drum edge. When in neutral align the two marks. Then tighten the bolts properly. :D

That's it? I think I might be able to cope with that Phil. Note the word might!

[quote=skidlids]Yes Brian the Haynes manual covers it quite well, nice pic of centreing using a ruler and the use of scribed lines to check up and down movement Quote

I have a tool for setting that up! Makes the job very easy & more accurate

Homemade?

Simon. You're earlier query regarding the 'stopper arm' on the clutch side is not without foundation. All that's been said regarding setting the lever arm correctly is valid, but the 'stopper arm' can gall on its pivot, slowing its action and intermittently preventing it from doing its job. This is often overlooked in the belief that all selection problems stem from lever am adjustment. It's worth checking for smooth operation.

Very true Andy, but there isn't anything on the clutch side of the engine to influence gear selection per se.

You must be running a different engine to me then Phil? :D I am referring to the Gear Stopper Assy (Ducati's description), which is definitely in the clutch side in my engine. If this gets too stiff, or indeed the spring breaks or weakens, the drum can over rotate by 'beating' the positive stop on the lever arm.

I'll have to discuss this with you face to face as I can't recall anything in the right hand clutch housing that affects the selector mech. Its that fkin Desmosedici you have in yours you are thinking of. :D

Steve's right Phil. This is the reason for the 1mm spacer on the wet to dry clutch conversion.
