I was told ( by a regular dragbike rider ) to do the following on MY bike to help me have fairly good results ( under 10 sec ) strap down the front ( within reason, don't want to bottom out ) and lower the rear about the same ( this is on a stock wheel based machine ) - soften the preload, slow the rebound ( would probably take a few "good" passes to tinker it in correctly ) and drop my rear tire pressure to 15-20lbs ( to begin with ) and run the front tire at normal psi. Clutch work is key along with near perfect shifting. Gearing is played with dependant on your engine rpm when you cross the line ( don't want to be out of pull before and don't want it shifting just before either ) so that's another variable to deal with the more you run it. Use lightweight oils ( 0w or 5w ) to help the engine spool up as quickly as possible. Drop in the least amount of fuel possible to complete the run with the highest octane you can map for. Airfilter in or out is up to you, the gain is small but could play a part if you're trying to break into that next 10th of a second. Lighten the bike as much as possible by stripping whatever is considered ballast, dead weight slows you down but you need good aero so the bodywork stays. A clean and sleek bike is a quicker bike? He said something about waxing the entire front down for just a little less drag. Pull your mirrors! Brock Davidson estimates it takes on avg. 12HP to push a pair of mirrors down the 1/4 mile. I'm sure you wont want to gut your bike and build a strip-only machine, but if you can apply any of the above it "could" better your chances in trimming your timeslips that much more. Hope this helps - btw, did you go run it yet?
