Would you consider selling me one of your clutch centres. They seem to be harder to find than rocking horse s**t at the moment.

The one I'm putting on the bike isn't the right one and I had it machined just this morning to make it work, the issue being the splines were not long enough to hold the lock washer. The other one is completely and utterly knackered and too far gone to do anything with. It was also machined in a practise run for doing the other one. I wish I could help.

(Added)
The knackered one doesn't fit on my mainshaft; it comes up against a shoulder (I think) before the tapers even meet. I was given it (Yep, it's really that bad) so I don't know much about it.

750rideruk,

I forgot to ask. What is the problem with your old one?

Below is the knackered one. The photo is quite flattering; it's far worse in real life!

I may have a solution for you. This is a thread I started some time ago, and I've just posted my conclusions:
