I Think you would lose top speed and gain acceleration. Why not just regear? It's cheaper and alot easier, I spent $20 and dropped the top gear down on my '01 mxz 700 and it made a huge difference in acceleration, It lost very little top endmaybe 3-5mph once you hit 100 whats the difference. Unless your doing radar runs.
We have had some debates on this before and no one has "really" come up with an honest answer yet.
My theory is a smaller sproket like a smaller bottom gear will make you go faster? Smaller top gear slower top speed.
Look at a dirt bike, they have a huge rear sproket for hill climbing and low end grunt. Same goes for a snowmobile, bigger bottom sproket lower gearing more grunt.
So does this all change when were talking where the track or tire is actually connected???
You have to look at it as two seperate pully systems, the drive sprocket will always turn the same number of revs. as the bottom gear. Changing the track sprocket will have no effect on how fast the bottom gear turns, but it will turn the track at a different speed. Changing the gears in the chaincase will change the speed the bottom gear turns in relation to the top, but the track sprocket eill still spin the same revs. as the bottom gear.
