bigboreshee Posted January 2, 2004 Report Share Posted January 2, 2004 I just switched out my stock airbox for dual k&ns and now its spittin and sputtering. I need to know what needs to be changed(main,pilot,needle). I checked the mains they are 190s, needles are in the middle position and have the letters 5n7 on them, I wasnt for sure where to check for the pilot.

eehsnab2 Posted January 2, 2004 Report Share Posted January 2, 2004 What elevation are you??? I am about sea level here and run (most of the time) 30 pilots and about 300-310 main in the stock needle postion. I have about the same mods as you...

SHEEGUY SMOKEDYAA Posted January 3, 2004 Report Share Posted January 3, 2004 Definatly go bigger on pilot for easier starting. Man those clamp ons change your jettting move a lot more air!!! I have ran as big as 380 main during summer. Jetting varies like attitudes every bodies is different. Sorry to say it but it is really a trial and error thing man no body is going to be able to tell you exactly what you need. Quote Link to comment Share on other sites More sharing options...
banshee04le Posted January 3, 2004 Report Share Posted January 3, 2004 definitely go bigger on the main...your pilot is probably ok...if it starts without a whole lot of kicking your current pilots can probably be dialed in w/the air screws for good throttle response. 190 is way to small on the main for that filter mod...dont ride it hard, if at all, until you jet up cause you gotta be dangerously lean. i would probably start w/at least 320' and if shees boggin rich (do a plug chop test) come down a size at a time until shee screams. rather be a little rich than lean if you concerned about reliability. 320s could even possibly not be big enough...do a chop test Quote Link to comment Share on other sites More sharing options...
SHEEGUY SMOKEDYAA Posted January 3, 2004 Report Share Posted January 3, 2004 5n7 is the stock needle. middle postion is probably okay those clamp ons are drasticly changing your jetting issues!!! A hard start would be pilot or a need to choke after a short down time between starts. (HARD STARTING)Would be pilot, 25 is stock. Jetting is a difficult issue no one is going to be able to tell you exactly what you need. Banshees are an awsome machine and their limits are unlimited or by your pocket book. A 300 main would be the smallest I would start with 27.5 to 30 pilot. do not run it to hard until you have your jetting dialed in!!!!!!!!!!!

Aussie Quad Racer Posted January 3, 2004 Report Share Posted January 3, 2004 if these are the standard 26mm carbs i would suggest start from 400 mains and play with it from there. Quote Link to comment Share on other sites More sharing options...
Banchetta Posted January 4, 2004 Report Share Posted January 4, 2004 I'd start w/ 330 mains, and do a plug chop after a wot run for 5-10 seconds in 6th gear....then adjust the needles one notch either way and find the sweet spot, then adjust the pilots and air screws.....might want a larger pilot or not. every shee is different in certain areas...You will blow the motor w/ the 190 main though, so I wouldn't ride it anymore until you put larger mains in...
