i have been looking and looking and i just dont have a clear answer on which is better! i looked at an old dirtwheels mag where they put kx cams in and they noted that the KFX was not only the fasted during the shootout, but it was a "MONSTER", stating that they would like to put it up against pro machines right off the bat. so anyways, i have looked at a million forums and i still just dont have a clear answer... which one is better for me? my kawasaki is already pretty fast with the yoshi pipe PIM2, pro design intake, and pro tec lid. before i go any further, would a FCI be that much better than the intake set up i have already? i noticed a big difference from stock to pro design, but am curious if i will notice a big difference if i switch FCI from pro design. but i want that answer secondly. the first answer i would like is which cams will be better? i ride around town and the cops never bother me, so i go as fast as i want. more importantly, my friends all have different bikes, all 450's. my bike was origianally the fastest, but after time they are all droppin cash on thier bikes and starting to catch up... not cool. i know i need to upgrade the cams. we drag race a lot. at least one time every time we ride. more importantly, i am going to Glamis on Easter weekend this year. i want to race a few people there, and i want to win. i dont want to beat 9000mil stroker super duper charged NOS infected banshees, but i dont want to get dusted by a dude on an outlaw or KTM 525... so that is what i am shooting for. thanks for the help!
