Blueish header pipes

[Drtridr18]

I live in northern Ohio, an just put on a Yoshimura slip-on, K&N Filter/Outerwear, Dynojet Needle on 3rd clip, Dynojet 146 main, and mixture screw about 3 7/8 turns. aybe this is normal, but until it gets warm, it's got a snap-crackle-pop-backfire kinda rev to it, once it's warm though it seems to run real good, the occasional light backfire sound on downshifts, and my header pipes near the head are bluish. Sound right to you?

Thanks

i dont know about the snap crackle pop, but yeah, the discoloration is normal. mine is the same way. i think it looks cool. I have a FMF megamax 2 complete system.

the slight backfire on deceleration means your probably running a tad on the lean side. try goin up a size on your main jet.
