juiceboxxx26 Posted November 9, 2010 Report Share Posted November 9, 2010 Hey i got a 96 banshee with Full FMF Pipes and exhaust full air box with a k and n air filter. Stock carbs elevation is sea level NY City jets are 250 Mains with 30 Pilot jets. Why is she sluggish when first moving but when it hits mid range to Top end it hauls ass ??? when idling it idles fine but when i go to rev it , it sounds terrible when reving it up Quote Link to comment Share on other sites More sharing options...
ECshee Posted November 9, 2010 Report Share Posted November 9, 2010 I guess theres quite a few things that could be impacting your problem. But first, i would start by doing the following: 1. run the bike with no airbox lid. it breathes alot better. 2. bump your mains up to 280's 3. drop pilots to 25 or 27...whatever stock is. 4. how is spark?

You may need to adjust your air screws as well. Quote Link to comment Share on other sites More sharing options...

juiceboxxx26 Posted November 12, 2010 Author Report Share Posted November 12, 2010 ok so at second look i am not a 250 main im a 290 main and i dropped the pilot to 25 cuz thats all i had, it sounds a lot better than it used to now i can also use the idle screw to adjust the idle and it finally actually adjusts. but i haven't touched the screws on the sides of the carbs yet. i am still running with the air box lid on, should i remove the lid??? and which way do i turn the screw on the carb to lean it out ???

bansheesa Posted November 12, 2010 Report Share Posted November 12, 2010 I ran the same setup a few years back. Perfect jetting for that at sea level is 25 pilots, 2-2.5 on air and 280 mains with no lid. You'll love it! Quote Link to comment Share on other sites More sharing options...
