I have a 300ex that has no airbox lid,k&n w/outerwear,cam,hc piston & cobra exhaust. Its been jetted with a dynojet jet kit stage 2. It has DJ128,38 pilot 2 1/2 turns on the screw, needle is set like dynojet says. My question is if I get a wb header & hmf pipe combo do you think my jetting would be ok. It runs just a tad rich right now, but not enough to hurt performance.

Also does anybody have any pics of a wb header & hmf pipe combo on a 300ex with the rear plastic taken off so I can see everything?
