| Good update on the gearing chart Kev,but how come the speeds at 8000 rpm have gone up from your original chart!
The thought of 4mph extra maybe more than i can handle.
To kind to the bike to rev it over 9000rpm and on mine the power plummets anyway.I beleive altering the cam timing will let them rev more or for longer but not sure if its worth it.8500 in 4th and into 5th seems to work for me.
I,ve tried Skids gearing so far to be spot on for me[Later 600ss]. Thanks Kev |
