I recently installed a 9oz heavier flywheel in my yz450f to smooth out the power when im MXing it, I also do supermoto at a local kart track and was wondering if it is hurting me on a sumo track with the heavier flywheel weight.

also i cant find the link to the Excel spreadsheet for gearing for the 2006 yz450f. does anyone have a link to it?

The flywheel has more effect on low gear operation than high, and may actually help in the big gears.

As for the gearing chart, advanced search, keywords gearing AND calculator, no exact name, second hit:
