drop a tooth or 2 on the top sprocket. If you go 2 teeth watch you rpms when you launch to enshure you do not over rev.

I changed gearing on my 01 formula 700, heres what I did. I long tracked it (from 121 to 136" track) and added 162 studs, so I dropped 2 teeth off the top gear, one tooth because I wanted faster acceleration and the 2nd tooth because of the longer track and studs. Had to change the clickers on the primary clutch 2 clicks, to keep the rpm's down. (there may be a better way to change the rpm's, but...? ) I think in the end 1 tooth would have been enough, with 2 it would be great for off trail riding, wet snow, towing, stuff like that. I wonder if clutching changes would help, maybe heavier weights or pins to get faster shifting of the clutches. Hope this helps.

so if i were to drop one tooth on the top gear, and just leave the bottom gear alone? would i have to worry about clutching and over reving at all?

i don't really have much money to spend htis year, so i'm just trying get a beat more accelaration without spending to much cash, that's why i'm trying to stay away from clutching.

thanks abunch!!

Yeah, most times you can drop one tooth on the top without changing the chain or lower gear. And the top gear is cheaper then the lower or a chain. You may have to change the clickers on your clutch (freebie!) but that should be about it.

If you have your owners manual, it will explain how to change the clickers and which way raises and lowers rpm's.

If you lower your clicker, your rpm's should lower ( I think 250-300 rpm per click)

alrigh thanks guys, as of now my clickers are set to 2 i believe, i'd have to double check, and i believe i rev out at like 7600-7800??, is there a general rule of thumb tha ti should follow when switching gears, ex: if i drop 2 on top do i drop 2 on bottom as well? or can i just leave my bottom one as is? if all i'm looking for is more snap ?

Just change top gear

like 01machz says, just the top.

just for reference, adding teeth to the bottom gear does the same as removing teeth from the top gear.
