tsharktim Posted May 17, 2012 Report Share Posted May 17, 2012 So I need some help figuring this issue out... my buddies shee will barely idle and has shit for bottom end about 1/2 it screams. the bike has fmf gold series, bossen reeds, k&n filter, no airbox lid, 25 pilot jets, 250 mains, stock carbs at 700 ft and 70ish temp. we tried 30 pilots cuz thats all we have and it seemed worse but with the 25s and 250s we started w the air screw at 2 turns out and it was running better at 4 1/2 screws out. I think it needs 27.5s but would one size make that much of a difference. Im not sure what else it could the compression is 115, and the plugs look oilly too. and tors has been deleted too any ideas would be be great.

Phelps Posted May 17, 2012 Report Share Posted May 17, 2012 put 27.5's back in at 1.5 turns out. if it need turned out to run clean the pilot is rich, if in needs to go in from 1.5 it's too lean. Quote Link to comment Share on other sites More sharing options...

Ran dam good with 320 main, 25 pilot, needle 4th clip. Fattys love 4th clip. Oh and any time you go beyond 2.5 turns out you need to go smaller on the pilot. Below .5 turns and you go bigger.
