chrisg987 Posted July 1, 2012 Report Share Posted July 1, 2012 (edited) Okay so i have a 2002 yamaha banshee with fmf fatty pipes powercore 2 silencers and a white brohers racing boost bottle. I recently picked it up and i dont think the guy has the correct size jets in it because it bogs when u give it throttle after idle but then it clears up and runs great. I was wondering if you guys might know what size jets a banshee with those mods should have. And what running the wrong size jets can do to your engine. Thank you.

Dahl87banshee Posted July 1, 2012 Report Share Posted July 1, 2012 Ditch the boost bottle for a stock cross over tube. They do nothing but crack your intake boots. I would try a 27.5 pilot, middle clip on the needle, and about a 280 main. Those are just what most people run though if you want to get right on with jetting we need your temperature and elevation. That should put you pretty close though. Quote Link to comment Share on other sites More sharing options...

Thanks and i dont wanna look like a dumbass but what do you mean by temperature and elevation and i dont relly wanna ditch the boost bottle because i like the throttle response. Would you have any idea as to why its boggy for a sec? thanks again I could post a video of what i mean by boggy if that would help you figure out what i mean.

It's a gimmick. Ditch the boost bottle for a stock cross over tube. By elevation and temperature, he means, what is the elevation where you will be riding and what will the temperature be where you ride? Elevation and temp affect your jetting.
