Your problem sounds slightly vague. Usually when the clutch slips it's most noticeable on high gear at maximum torque rpm, something around 5000-7000rpm in EFE case. You can try blipping the clutch quickly at full throttle there and try to feel it graps right away when you release the clutch or if it slips there.
I have also heard that the 2nd gear can get loose on the shaft but haven't never vitnessed that. I would assume it isn't recovering when it lets go.
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.

I had an issue for many years with clutch slip (like 30 years on & off!)
I finally found the problem last year when replacing the plates yet again. I noticed looking through the drilled holes in the pressure plate ( these were an addition on later engines) that there was very little clearance before the pressure plate bottomed out on the inner basket, thereby preventing the springs doing their bit. I messed about with some slightly thicker plates to increase the clutch stack height & problem solved. I should have spotted it years ago but I have no idea why it happened in the first place. Tolerance buildup maybe, who knows but it's worth having a really good look & measuring everything.
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.

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.
