Hi Paul,

Most Jap bikes are 1 tooth to big on the front (aprox 3 teeth on the back).

The way I do it is to setup the gearing so that I am just off the redline in top flat out.

I was going a bit quick on a zx12r to get it right but it's apart of the fun right :)

For any PC plods on here I was on a closed road honest he he.
