Hi, I just got my 450 last thurs. and haven't really had a chance to ride it yet. But I did get out and start it and piss off the neighbors riding in my hood. I did the baffle/snorkel and grey wire mods. I have the JD kit ordered. What I'm wondering though is whether it is normal for the header to glow red? I started it up and let it warm up for a couple minutes while I grabbed my gloves and helmet.
When I looked at the pipe it was glowing red for about the first 8" out from the head. After riding it for about 5 minutes I brought it back to the house and shut it off without idling it. The header was still glowing dull red out 3-4" from the head. Does it just need the jetting richened up or will I always experience this. By the way I love the power of this bike it blows the XR400 I've been riding away.
