elwilliams13 Posted September 26, 2008 Report Share Posted September 26, 2008 (edited) If you are at a 330 main you might be rich for your mods. When I ran your same mods I was at 280mains stock pilot and needle position(#3). Thats what I ran at sea level. The added compression might change your octane requirements depending on how much was milled off.

jbones Posted September 26, 2008 Author Report Share Posted September 26, 2008 (edited) smaller main jet, 330 is huge for those mods i run 32.1 mix 93 octane the idle screws are turned almost all the way in there is about 3 or 4 threads beteen the locknut head of the screw also seems to bog if u hit the throttle real fast. could it be eletric problem ? the longer u ride it seems to snap out the problem and run good?
