robsully5150 Posted January 19, 2007 Report Posted January 19, 2007 I have a 2006 Shee' with FMF fatty pipes, boysen power reeds, powercore 2 silencers, boost bottle, and i am currently running .270 main jets. I have a kit that has .340 mains and i was wondering if I should change to the bigger jets? Am i missing out on some power by having the 270 main instead of the 340? Or will it be too rich and run sloppy? I was unsure considering all the mods what jet i should run and how many turns on the air/fuel mix screw. I am in no elevation. Thanks for any input. anybody have a dynatek ignition?? and if so are they worth it? Quote
Handyman Posted January 19, 2007 Report Posted January 19, 2007 I would say that 340 would be way right for you unless you are at like 4500 feet above sea level. You should run no bigger than a 300 or a 310. FMF's also like a bigger pilot jet(27.5) Quote
