This is nothing new, I have had the bike since new April 1976 and it has always been the same.

Dennis,
Hopefully somebody on this forum will remember the known cure for your problem, I think it's something to do with oil not escaping properly from the clutch basket and maybe causing clutch drag?
I'm able to select neutral ok on my F1, but was horrified when I inspected the clutch and discovered the PO had cut small grooves on the faces of the steel clutch plates with probably a file or hacksaw blade.
But the clutch had been working fine so I just bit my lip and reassembled it and have now done over 30k without a problem.
Spitfire:
Thanks for that, I do seem to remember something along those lines, as to your bodgy job, if it works then it was not a bodge.
Nowadays I must admit that the thought of ripping the clutch apart does not thrill me.
The olden days when I would wrestle a 750 engine out of the frame on the drive by myself and rip it to bits are long gone so I will leave it as it is as it still drives and rides nicely.
Thanks and Cheers
Dennis

Thank you again, started on the clutch strip but the special nut is causing me a problem, I made a tool from an old socket which is fine and fits well, but when I try to undo the nut, the whole lot turns, is there anyway to lock the clutch to undo the special nut please??
many thanks for your help

That shaft should be "drive" to rear wheel, so put in gear and hold rear brake tight.

Also an impact wrench is handy for jobs like this, but if you don't have one try a sharp blow with a hammer on your socket bar.
Good luck.
