I've placed 1st in 500 stock and 1st and 2nd in 500 modified for the past 4 weeks of racing. We run 300 ft in the dirt. Heres set up 13/42 (2nd gear starts) 22-11-10 8 paddle Haulers,and shorter shocks on the front 14" center to center, run enough spring preload so the shock is fully extended, this helps prevent wheelies when you launch the bike. Last weekend after the races we did some fun runs and I raced some full modded Banshees and beat some of the by 1 1/2 bike lengths and the ones that could beat me only got me by 1/2 a bike.The carb has been massaged a bit, I cut 1/2" off the spring, DJ needle, 160.5 main, 50 pilot, and k&n drop in.
