okay my banshee is an 05 only performance things are toomeys and a K AND N, airbox lid off and wiseco pistons. its acting funny, at idle the right side idles higher then the left and warms up much quicker like the right pipe will be too hot to touch but I can grab the left one. when completely cold like first time starting for the day sometimes when I pull out the left cylinder acts like its not even firing, no smoke comes out but only when I take off sometimes, also I can feel when driving slow the left cylinders power will kick in and out and it will jerk but again only when cold. once warm it pulls great its fast as crap but still the left side idles lower. ive changed plugs switched wires and no matter what same results, any ideas? also compression on cylinders is within 2 psi of each other, the left one being 116 and the right being 118.
