Went for a night ride on a 2002 WR 426 that belongs to my boss. I ride a 01 Yz426. I have never ridden my bike in complete dark (no light) so I don't know if my pipe gets that hot. The WR's pipe was glowing red. Is this normal. We were riding at 6500' and the bike has stock jetting.

Gee I dunno mate-I did a search and this topic has never come up before. Best thing would be to sell it before the motor blows up!!!

No its DEFINATELY NOT NORMAL!! This is the first time I have ever heard of such a thing, and I sure as hell didnt see another post just yesterday on the same topic. This is a very rare-most likely a production malfunction which would have resulted in all your valves being burnt out!! Destroy it IMMEDIATELY

This is normal from what I have seen and heard. I know the search function rarely works but there are plenty of other threads on this subject. Lots of 400-450's glow when stopped but should go away once your moving again.
