I just got back from a hard 3 hour ride today and noticed the header pipe where it comes out of the head was a deep redish tint with just a few bluish spots. The bike runs very good with no hesitation or flat spots and I had it wide open in high gear today for a few 30 second jots...
I'm wondering if that is a normal color?
its a KFX 400 with Yoshimura Comp 3 full exhuast, k & N filter with the top of the air box off and a 150 main jet.....I'm going now to check the spark plug and maybe change the jet to a 155
