Faster!
I'd get into the rules and read them real close! Depending upon the type of track one of the things that you should be doing is changing your gears, both front and back and have some extra chains for the different lengths, caused by the different size sprockets. Guys even on the road seem to never get this in their heads. If you have a"Top-End" that is over twice the Legal Speed LIMIT, then for what it is worth change your gears and use the power and limitations that you have...a bike is built like a car. It is built for the AVERAGE Joe. You want speed you can change things, you want more usable power you change things...you change things! I don't cruise the interstates, so I'm interested in changing my gearing for blasting the tight and twisties. I'd be almost red lined to be doing the 75MPH speed limit when I get done with my bike. Tires are another issue. Depending upon the track conditions hard clay loose mud, you should havea not only gear changes for this but different tires. Flat tracks and tihgt twisty hilly tracks...I went to an event last year that was on a field with big tractor tires on it...nothing but loose grass and packed clay, no burms, a really short track, and lots of dust. check out your track conditions and set up accordingly...find some guys that race all over an ask them things about the different tracks...or if yo are just going out to a regular social event whre everybody runs...find out what you have for trrack conditions and watch our RPM's...pay atention to what you have and what you can do to improve...also check your shocks and see if adjusting them will improve or hurt and record each tihng that you do seperately never make two different adjustments at the same time!!!
