it wasn't till last race season that i finally built up a bike with a bigass expansion chamber, carb, and afyermarket head. i had to do it to keep up with the arrow team.
i was leading the first coupla laps in the final of the last ride til my pedal seized and fell off, and i had to pull off the track. wait'll this year!
i always got a kick out of racing everyone with the stock, albeit heavily modified engine without all the bolt on goodies, but after 2 years of 3,4,and 5th places i finally had to cave in and build something to compete for first.
i'd love to have a race class where all modifications are allowed to the stock kit, but it has to use the factory carb, exhaust, head, etc. no aftermarket parts allowed.
