Stripped the clutch in my 350 yesterday. Really confused indeed. Friction plates with inner tags which I think is normal for late clutches BUT tags approx. 8 mm, which I think is pre -56. Cluth drum also splined for 8mm tags. Centre cover fastened with not the usual three countersunk screws but with 6 allenhead screws. The spring retaining nut not the normal slopped screwdriver type but have a 1/4" inner square. Of cource lightened clutch basket and pressure plate.
Bike had 9 years of serious racing and after that 25 years of occasional classic rides. After that 20 years rest. Now to be started again.
Now to my questions. What is the original setup? Where does the parts come from?
