Could someone look in their shop manual and post the gear ratios for the WR 426? I've got an 02 YZ and I'm thinking about swapping out the gearbox. Thanks ahead of time!

Thanks a bunch. I've been wondering what they were since shortly after Yamaha removed the info for the 426 and replaced it with the 450 stuff (sans gear ratio).

thanks again
