I know I would like to go two fewer teeth on mine.I have made cogged pulleys for redrives on homebuilt aircraft and have considered doing the same for my Savage, would really like a comfortable cruise in the 70 mph range with a lower rpm and a tooth or two might do it, I'll tool up to make duplicates if there is an interest .

I have seen where several folks have mentioned changing the final drive ratio by putting a smaller belt-drive pulley on the rear wheel...but it occurs to me that there might be an easier way to go about getting a different final drive ratio.
Has anyone considered putting a smaller primary-drive sprocket on the input side of the transmission? Suzuki makes a boatload of bike transmissions...I bet there's a factory bolt-on in the neighborhood of 20% smaller. Working out the right length of drive chain might be tricky, but if it worked, it would all fit under the stock primary drive cover.
Of course I'm assuming that the primary drive is a chain and not a belt...I'm a newbie in every respect, so I don't know for sure.
A 20% smaller input sprocket on the tranny would yield 20% more top end, assuming the bike has enough power to top out the rev range. That would turn an 85 mph bike into a 102 mph bike with more liesurely acceleration. Fuel economy at highway speed should be unchanged, or perhaps a smidge better.
