i think jeremy makes some good points about bike selection. one thing i think to remember is that you dont want to get in over your head with power. the most important thing to remember is to pick a bike that you feel comfortable wringing the crap out of. at the track i ride the 350 at speeds i wouldnt dare to on the street. having a bike thats a little down on power is ok for the start. it does actually teach you alot about how to ride and how fast to go. aaron and i have had this same conversation many times. dont forget, you can pprobably always hop it up some with cams pistons carbs etc and move to the next class. the classes that have the closest rcaing are the ones with the craziest riders, but they are also the ones with the closest matched bikes. kinda like iroc. be sure you have a good parts availability. cranks and pistons are important things to be able to get in 2 strokes no? make sure you have a good line on them as well as tranny parts. dont race anything youre really attached to. if you value it to the point that you dont want it destroyed, the track isnt the place to take it. it takes only a blink of the eye to have something at the track completely destroyed. although it is rare. ok, i have to go pet my zebra.
