Is it possible to change individual gear ratios, rather than changing sprockets? The idea would be to lower first gear quite a bit, 2nd a little less and so forth until 6th maybe would not change at all, or would maybe even be made a little taller.
Guys like Barros and Bayless are changing ratios to fit particular needs of each track, but generally their ratios are pretty close with a tall first gear. Spreading out the ratios, would mean a greater RPM drop between each one. I don't think you'd get the magical gear dances through good bits of road like you can with a close ratio box.
