Also your air screws probably need adjusting too. What do you mean " i noticed i have 2 strok oil coming out up front and a little out the back"........? If your meaning oil is coming out of the front and back of your pipes, you need new orings on the headers and a repack on the silencers. Or is it leaking where the stinger and pipe connect? Quote
camatv Posted June 21, 2011 Report Posted June 21, 2011 i hate 30 pilots in mostly stock / modded banshee's i really dont know why they get recomend all the time. they are mostly too RICH 27.5 is a nice middle from stock. most of the ones i have worked on over the years have really liked 27.5, needle in 4th pos from top, and 280-340 mains. mikuni carbs rely hevily on main and needle for jetting.

03banshee20 Posted June 22, 2011 Author Report Posted June 22, 2011 I have brand new exhaust sEals up front and new silencers in the back i think thats all fine Quote
