| SP2 Clutch problem
Next installment of the SP2 saga - had 3 hours of great riding over the weekend, no problems, so I decided to take it to work on Monday (a 140 mile round trip). Went fine until I got to the built up areas around Kidderminster, then I had problems getting neutral at traffic lights. So had to hold the clutch in all the time. Not good for my left hand or the bike !
Eventually, the clutch gave up, fortunately only 30 yards from work. I thought it might have just overheated, so when 5pm came, I started it to go home, and the clutch really complained, with tiny bits of metal coming off it.
Time to call the AA I thought. They took me home, and so tonight, I've just dismantled the clutch and found the problem - technically speaking, it's completely shagged ! The friction plates have about 2 microns of material left on them, the main clutch basket with the 6 extrusions that the springs bolt into has been totally bodged at some point in the past, as one of the extrusions is completely missing, and another has been welded on, the allow outer part of the clutch as cracks appearing in the well holes, the main nut holding it onto the shaft was loose, and the locating pin of the housing where the nut fits had broken off, plus there seems to be about 8 more plates than the workshop manual indicates there should be - there were 2 plain plates, then 7 sets of friction/plain plates when the workshop manual shows just 4 sets of plain/friction plates.
So, anyone know what the alernatives are for replacing the whole clutch assembly - will a 916/748 type fit and if so, are there any extras that are needed ? Or do I have to try to find an SP2 one, and if so, are there different types that are better than standard ?
Also what's the method for holding the shaft tight (no s******ing at the back) whilst the main centre nut is done up ?
Thanks for any advice lads.

(what's the third thing to go wrong I wonder ? Fire, Clutch ... any suggestions ?)  |
