Did you get my email yesterday?

 

Yes. Was waiting to double check the manual before replying.
However, I'm 99% sure there's no difference in the clutch between the
R and RR models. Both have three thicknesses of steel plate available
- by using various thicknesses, you set up the height of the clutch
stack to be within a certain range.

It was me being clever with this before Brands Hatch that caused our
problems. The stock ZX7R has a slipper clutch fitted, but the
standard set up doesn't allow enough movement in the clutch stack for
it to properly activate on the overrun. According to the race kit
manual (and as advised by Slick Bass), you put a couple of thinner
steel plates in - this allows the clutch stack to ride up the ramps in
the clutch sub-hub and disengage on the over-run. However, for some
reason which I've not yet worked out, it slipped immediately unde
drive. Putting the original steels back in didn't fix it, and while a
new set of friction plates made it work for a while, there's obviously
something else going on.
