ojcool Posted April 30, 2006 Report Share Posted April 30, 2006 Hmm, I just wonder sometimes how you guys run such rich mains with this setup. My neighbor has: 2004 Banshee +4 timing K&N Filter kit Fatties W/ Powercore II silencers He has 270 Mains in it now we tried to put in 300's and I could not even get the bike to stay running no matter what I did with the pilots. He has the Dynotune needles. We have not had time to do the plug chop yet, I think we will end up with 280's in it. I just see people posting running 300+ mains with these mods and I can't see how that can be. We are at 187 ' elevation. Every bike is different but it seems like a big difference to me.

ojcool Posted April 30, 2006 Author Report Share Posted April 30, 2006 Oh, BTW FMF says to use a .30 pilot with these pipes, anyone doing this? Quote Link to comment Share on other sites More sharing options...
pipebomb Posted April 30, 2006 Report Share Posted April 30, 2006 (edited) Gee thats funny. I'm running 240's w/ my Fatties and it's still a bit rich. and the slip that came w/ them said to run the stock #25 pilot.(needs to go to a #27.5 at least, a little cranky to start cold.)

pipebomb Posted April 30, 2006 Report Share Posted April 30, 2006 sorry my mistake, found the slip. said #30 pilot. guess I still need to up the pilot anyway. still got the 240 mains though. Quote Link to comment Share on other sites More sharing options...
Hilarious Posted May 1, 2006 Report Share Posted May 1, 2006 Everyone's bike is different. I had 340 mains with my fattys with K&N pod filters and it ran like a monkey with his nuts on fire lookin' for a watering hole. Outside temp and Elevation are big factors in your jetting.

watkins Posted May 1, 2006 Report Share Posted May 1, 2006 I second Hilarious... when i ran that same setup at sea level i was at 310 on the mains, stock pilot and dynojet needle in the 4th clip and it ran & plug chopped perfectly. Everybike is different. Quote Link to comment Share on other sites More sharing options...

yellabanshee Posted May 2, 2006 Report Share Posted May 2, 2006 running my banshee at 320 and 27.5 pilots..........runs like a raped ape.... elevation sea level in portland oregon. air mix screw at 1.5 turns out:) good luck by the way, I tried the pilot at 30 and it would not even start, so.....I would try the 27.5 if I were you Quote Link to comment Share on other sites More sharing options...
ojcool Posted May 6, 2006 Author Report Share Posted May 6, 2006 Wow, huge difference. Well we're going to work on both his and mine tomorrow and do plug chops. We will see where we end up. I just wonder if float setting variances have much effect on fuel mixture. thanks for the input though guys. Quote Link to comment Share on other sites More sharing options...
