It's a new cable and there is play in the pinion lever when clutch should be engaged. I will strip down clutch and inspect everything to see what I can find.

Its quite noticeable in 1st gear under hard acceleration. No pulling your arms out of their sockets and will not get much above 25 before you have to change up. Also if you crack open the throttle in any gear there's no real pull, just a gentle acceleration. Top speed is not far above legal limit. Rev counter also hunts and doesn't move in relation to speedo.

That's something I haven't thought of. I know that there is a set of clutch plates for it with extra plates available, think APE do them, so that could be a way to go. I have measured the steel plates and they are well inside tolerance.

I had been using a semi synthetic but reverted back to a fully mineral in the hope that it had something to do with it when I was convinced it was a clutch issue.

Sorry for such a long post but this has been a long term problem that I have been trying to fix for a looonnngg time. It feels like the clutch is slipping upon acceleration, especially in lower gears and higher speeds are generally not possible. So far I have changed clutch plates going from EBC to original ones. Replaced both the inner and outer clutch baskets and fitted heavy duty springs, all to no avail. I remembered reading somewhere that one of the gears can spin on the shaft so I looked in the workshop manual and found out that the 2nd drive gear is a press fit on the layshaft. It also states that this gear can be replaced twice before a new shaft is required. Has anyone else come across this problem and come to the same conclusion that the clutch isn't the issue? Any help or suggestions will be more than welcome.
