I've looked through a lot of the threads about the 'Tubular Nut' or 'Castle Nut' - that nut attached to the rear of the Clutch Basket that loosens off over time.
As it loosens, it can either give you the impression under hard acceleration that you've been 'kicked out of gear' (but in fact, if you quickly back off on the throttle, you find that you're in still in gear) or, as it worsens, you encounter the same symptoms of a 'slipping clutch'.
The Tubular Nut has 6 - lugs. So a tool with 6 -lugs would give you the greatest amount of torque while re-tightening the nut. (Besides, 4 - lug tools don't line up).
I found a 6-lug tool online which has an outside diameter of 2-5/8" inches.
So my question is this:
Has anyone actually measured the Tubular Nut? What are the Inside and Outside Diameters?
