mushman420 Posted February 25, 2016 Report Share Posted February 25, 2016 I have a 1998 banshee with stock cylinders and pistons. It has, Boost bottle Fmf gold series with silencers Dual k&n I'm at 2000 feet above sea level Days from 40 to 90 degrees I'm running 290 main and 30 pilot and it wont idle or even rev when i hit the throttle. It will just fire. I was thinking of going to 226 main and 31? or 32? for the pilot. I wanted someones opinion on that. Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted February 25, 2016 Report Share Posted February 25, 2016 First, ditch the bottle. It WILL crack the carb boots. What's air screw at? What do plugs look like? Spark? TORS eliminated? Parking brake? Has this thing ever ran, or has it gotten worse? Ever do a plug chop/read? Last time you actually did some maintenance? The jet sizes you mentioned do not exist.

hoppedupandcutdown Posted February 25, 2016 Report Share Posted February 25, 2016 Has it not run since the reed change? That's a super common spot for an air leak. Quote Link to comment Share on other sites More sharing options...
