gearing problem

so i think i got in a little over my head but not sure. bought a 09 zx10 last fall and ran it a couple times (ive been racing about 2 years now). this winter i put a full brocks short meg, pcv, and two step on it. i also lowered it 2 inches and have a strap for the front. i then went and put a 15 tooth sprocket on the front. i went to a test and tune this weekend and couldnt seem to keep it under control. should i be able too or should i jump up to a 16 or even back to stock. just looking for a little advice on where to set the 2 step and what to try

If your SWB... -2 in the front is going to be hard to get keep the front end down. I don't know your weight, but on my Gen. 1 I ran -1 up front and it was about perfect. Front sprockets are cheap enough, buy a -1 and try that.

-2 is approximately like going up 6 in the rear. Try -1 up front and if it isn't enough go +1 in the rear. I assume you are stock wheelbase?

when i had a -2 sprocket on the front i was always lookin at the sky. i would stick a 16t on the front and do all your gearing changes to the rear. maybe go up +1 or 2 and see if that helps.

The quickest run swb on my '08 was with 15/39 gearing. Very similar to if you went -1 +1 but with the added benefit of a little extra wheel base. Went 9.81 @ 150 on that pass

yes im swb have a stock rear sprocket and im about 220 lbs. i love the way it pulls with the sprocket on and its not coming up at the end of the gears just off the line i was having trouble. i was just wondering what everyone else was doing and if it was possible to leave the sprocket on.

im lowered, strap, geared -1 +2 which is 16/41 and i weight 200 pounds. if its just coming up off the line try straping it down some more or slidin the forks down the tripple trees to see if that will help.
