06bluebanshee Posted June 2, 2011 Report Posted June 2, 2011 Hello I have a low hour Banshee in great condition. I recently put on Pro Circuit pipes and silencers and a pro flow k&n air filter. My elevation is about 600 feet, in Chicago surburbs. I'm running a 25 pilot jet and a 280 main jet. The problem is when I get on it real hard it hestitates as soon as I hit the next gear??? It makes like a popping sound, then as I proceed to accerlate it clears out perfectly. Pulls hard on top end with no break up at all. Just when I change gears it stumbles right away?? I was wondering if you guys think the pilot jet is to small? Any suggestions or replies are appericated. Thanks! Quote

I dont know if that is problem for sure but it should make your banshee idle better and smooth out the throttle a little. Probably a little lean anyways with the new add on's Quote
wfobasheeboy Posted June 3, 2011 Report Posted June 3, 2011 Need more INFO on your mods, Like air box lid or no lid? ETC? I would go with a 27.5 pilot And up one or two on the mains & do a plug chop Quote
06bluebanshee Posted June 3, 2011 Author Report Posted June 3, 2011 Bike is all stock expect for the Pro Circuit pipes and K&N pro flow filter, stock air box no lid. I had 300's and 290's in it before and it still hesitated between shifts. 280 seems to be great for the main. I'm guessing its the pilot. Quote
madjimmax Posted June 3, 2011 Report Posted June 3, 2011 All piped banshees need a 27.5 pilot. Where is your needle at? Try dropping the needle clip 1 spot lower, which should be raising your needle, it'll richen it up some. Quote

Then play with the needle & check the plugs for the mains. My old set up was FMF pipes K&N stock air box no lid +4 timing. I was 27.5 & 330 mains clip in the middle for at sea level. It was spot on.
