badshee1998 Posted February 12, 2009 Author Report Share Posted February 12, 2009 no way to tell untill u run it... see how it runs, start rich and work down well i rode it with the 350s and ran good maybe a little sluggish on taking off, i havent done a plug chop but i pulled the plugs and on the rim and down in the plug looked pretty black and the porcelain was like brown.. rich??

magz Posted February 12, 2009 Report Share Posted February 12, 2009 (edited) 340 or 330.. i wouldnt go with 350 Blaster06, your still a newb at jetting with your own problems man, dont tell people not to try stuff, you dont know. for his locations and area temps his main jetting is more then likely almost spot on. if anything id say remove the 27.5 pilot, get a 25 and adjust your air screw, and needle position. he's probably just rich on the low end, but you should be able to adjust your needle and air screw to fix any low-in bogs Edited February 12, 2009 by magz Quote Link to comment Share on other sites More sharing options...
CBAIER1206 Posted February 12, 2009 Report Share Posted February 12, 2009 I agree... a 25 pilot will definately fix your bogging problem and your mains are prolly spot on as long as it pulls hard on top. You'd rather have it a little rich then run too lean and have an issue. A friend of mine uses 370 mains on almost the exact same setup and his bike is really quick. On my wifes bike, stock port with only a Toomey pipe and a K&N pods I just switched her to a 330 main and it's spot on. Unfortunately every bike is different even if the mods are the same, hence require different jetting. Just make slow adjustments until you are happy with it and you'll be fine! What you don't want to do is take jetting advice from someone that never even asked what alltitude you ride at.... :thumbsup: Quote Link to comment Share on other sites More sharing options...
