No nitrous, stock motor. Has a Muzzys m10 Full exhaust, power commander 3, and secondary flies removed, Aldo running in 93 octane pump gas. Looking for better times and mph, it has gone 9.36 with 1.51 6o ft. At 144 and I'm 220 suited. I have done 1.46 but bike was running lean. Taking it back to the track on Wednesday to look for those 1.4 60 ft.How are you planning on adding timing? Are you planning to use nitrous? Is the motor stock? Do you know how to detect detonation once the timing changes are made? What are your goals? Looking for ET or MPH? Club rider?
