Thruxton Thruxton R headers discolouration

I wouldn't say vivid blue, but the l/hand is certainly different to the R/hand.

 

I read on another forum that some had them swapped under warranty, possible cause is lack of proper cleaning prior to first start as they use some form of anti corrosion coating.
I intend to ask my dealers opinion when my bike goes in for its fuel leak issue

 

This is very common / normal for bluing of exhaust headers. It is due to the Air Injection system (part of anti pollution parts) to create an after-burn in the headers to reduce the possibility of unburnt fuel reaching the cat. This causes increased heat in the headers and they go blue.

However, the two headers normally go blue at the same time, so something odd is happening on your bike.

Incidentally the headers are made of stainless steel and have a tendency to a golden colour throughout their length, unless cleaned thoroughly with products like 'Blue Job' or 'Autosol'.

 

understand why the headers would discolour in the way that you describe, but its not the reason here and the "slight" issue is that it only seems to affect the l/hand side. i'll try to take a picture, but on mine it is more small patches of discolouration, akin to marks left by people with "rusty fingers" for the engineers on here

 

Interesting, one is running hotter! Could be a deeper problem that's going unnoticed.

 

Hi There,
I hope that you are all well. We are TTS, the manufactures of the Triumph Thruxton R supercharger that was ridden by Carl Foggarty at the Glemseck 101 in september.
I hope you like what you've seen so far. I just wanted to let you know, that we have produced these kits now for sale (Moderators, I'm not trying to sell here) but I have noticed a discussion regarding the bluing of the headers. In the quest for the most perfect ThruxtonR aftermarket addition, we have commissioned Scorpion Exhausts to create some beautiful pipes that work with and without our supercharger. Check these out. Hope you like them.
