Hey guys I'm new here and also new to the 4stroke mx club. After years of owning 2 smokers I bought a yz426. The thing needs a carb rebuild for sure, which I'm capable of doing myself. But the one thing I'm not sure of is a glowing red hot header. I took it for a spin around my block last night and noticed it glowing all the way from the head to just about the end of the heat shield. I've seen some posts saying that it's normal, but it doesn't seem right to me. I mean there's never been a pic in a magazine of some guy in a sx race with a red hot header. I only mention that because I'm sure those guys are riding their bikes harder than I have. Any suggestions?
