much thanks


Nothing is wrong icemann, this is very normal in these bikes, 400 and 426 turns orange and glow in the dark, so don't let the bike idling a lot, these bike really needs fresh air all the time, nothing is wrong with your bike, is a common symptom in these kind of monster bikes ! :)

It's normal for the header to get really hot. If you run the bike when it's dark you can really see it glow.

form wot i can tell guys this is pretty normal my 2000 426 does this as well i thought it was pretty cool the frist time it happened but my bike runs great so im happy with it
