I have a 93 900rr and I am going to start drag racing it since I fixed it. What is the best sprocket sizes to use?

-5 / +15 should do the trick...[sm=smiley20.gif]

You really need to tell us mods, power, and even then its going to take a lot of R&D.

D+D pipe and header, stage 1 jetkit, dyna ignition, lowered 3 inches, kevlar clutch. you think -5 +15 will do it?

40 shot of nos should do it.
