chevybanshee91 Posted May 12, 2011 Report Share Posted May 12, 2011 if you are running aftermarket pipes you are too lean. Jump up to a 320 jet and give that a try. then you should be right in the ball park. Quote Link to comment Share on other sites More sharing options...
badlarry Posted May 12, 2011 Author Report Share Posted May 12, 2011 (edited) i thought i covered every parameter. ooooops, duh, pipes .....! toomey t-5's and the domes are 21 cc . not 19cc Edited May 12, 2011 by badlarry Quote Link to comment Share on other sites More sharing options...
chevybanshee91 Posted May 12, 2011 Report Share Posted May 12, 2011 yea t5's you should be right at about 320-330 mains .. give that a try and see what ya think Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted May 13, 2011 Report Share Posted May 13, 2011 21cc is more like it because 158 with 19cc domes is more than mild porting,320-340,27.5 pilot Quote Link to comment Share on other sites More sharing options...
lincster Posted May 13, 2011 Report Share Posted May 13, 2011 I run 380 mains at 500' elevation with T5's and a 2:1 air filter. Bike runs just a tad rich, but I would rather have that than a hole in piston. Quote Link to comment Share on other sites More sharing options...
