as above really, just picked up this project, it has the largest mountain of service history I,ve ever seen for a bike, into the thousands of pounds lol and I cant wait to get stuck into it, anyway, is there any common problems which affect these bikes clutch wise, the lever just wont pull in at all just wondering before I get the hammer out. ta.

First thing to check is the clutch arm at the back of the gearbox, could be seized solid.

These bikes use splines to connect driven parts. There is a spline connecting the gearbox to the clutch plate. But if the clutch lever doesn't work, then maybe the needle bearings in the clutch arm are toast and it's seized. The clutch arm pushes a rod through the gearbox against the spring plate to release the clutch.

Get a manual now.

Not sure that this applies in your instance, but K100's had a device which retracted the side stand when you pulled in the clutch lever.

If the bike's on the side stand, this won't happen...

Oh... err better check that as well, pretty sure it was on its side stand when I parked it and tried the lever lol. Thanks again!

Many have been caught before with this trick. BMW put it there so as to increase the sales of clutch cables.
They usually get removed.

Assuming you have got the clutch arm down below moving and it is not seized then the other prospect is the clutch plates have bonded to the flywheel, it happens on cars left to stand as they too have dry clutches (those with manual gearboxes that is). One way to free that is to get the bike running on the centre-stand when warmed up and in top gear with the engine revving without shutting the throttle pull the clutch in and put the back brake on gently and then harder and harder. With luck the clutch will break free from the flywheel and all will be good to ride. I had to do that to my Saab which had been laid up for 5 years.
Regards,
