Glowing downpipe !!
 

started my xtx yesterday in the garage, just to let it warm up for a bit, but after 5 mins at tickover i noticed the right hand side exaust downpipe was starting to glow a cherry red colour!! the other one was fine. bike is bog standard 07 model with original pipes. anyone got any idea whats wrong? dont know if its done it before, just noticed it as it was nearly dark. cheers T

they do glow, but are you sure that both headers weren't glowing ?

the other header looked ok but i,ll check again at the weekend. thanks

Doesn't sound out of the ordinary. I wouldn't leave any vehicle standing to 'warm up' anyway. Start it up and ride off, ride carefully for about 5kms in order for it to warm up properly.

There is nothing wrong with the headers glowing, its fine and wont hurt it at all.

happens with all bikes if run in the dark and not moving, - would expect both headers though.

Perfectly normal - don't worry!

Thanks for the reassuring replies, took it out today for a blast, what better way to start a new year :laughing7: roll on summer :applause:

checked the headers today and they are both the same shade of red in the dark after about 5 mins idling, so all is well :laughing6:

But I guess the headers shouldn't glow on open throttle??!
Could a dodgey O2 sensor/lead cause the AIS to remain open? I may have "disturbed" it when replacing the exhaust seals.
