one exhaust header going blue
« on: Sep 03, 2007, 05:23 AM »
One of my exhaust headers has gone dark blue from heat (right side).  The other one is nice and golden.  Is it possible my right side is hotter than the left?  Is this a bad sign or sign of a problem?  The bike seems to run fine...

Anyone else have two exhaust pipes of different colour?  I've had a few parallel twins and the pipes always looked similar from heat treatment.

Thanks!

Jeff:

Your guess is the same as mine.  I'd ask my dealer to have a look at the fuel / air settings - but I'm no mechanic.

I noticed the same on my bike last night.  640 miles in and the right header is bluing;  it is possible there is more of an extreme bend in the right tube causing more heat than the left.  I dunno. :006:NVTS

No worry. It's looks that all 2 cylinder bikes have the same issue. Friend of mine has same on TDM 900.

Maybe one of the cylinders is just for show and the Versys is actually a 650 single!!  :whistle:

It's only a theory - but the water pump is on the left - the left side gases in the exhaust port will see more cooling from the water than the right - enough to make a difference?  - I dunno'!!
