Scott,

I think that those ratios should work pretty well at Willow. I am assuming that you have a good power band from 4.5k to 7.5k in your engine.

@4500 rpm with 26.5 dia. rear tire.

1=45.8 mph
2=57.8 mph
3=71.4 mph
4=90.7 mph

@ 7500 rpm with 26.5 dia rear tire.

1=76.3 mph
2=96.3 mph
3=119 mph
4=151.1 mph

The splits look good. I would just look at your current ratios and revs in the corners and see if the new ratios put you in a better point in your power curves.
