Thruxton I like it blue

I love it when the exhaust pipes blue up on the top bend. Currently the left hand bend (whilst sat on the bike) is starting to go a nice bronze colour with hints of blue starting to appear....lovely.

But disapointingly the right hand bend has hardly started to colour up at all........I've seen other comments on this Forum where other people have had this dicolouration in-balance.......the bikes not long had its 500 mile service so I am assuming (very dangerous I know) that the injection system was in balance and mixture spec was ok.

Does anybody have any recommendations as to how I can promote the right side to bronze/blue up to even up the look?.......thought about gently running a blow lamp over the bend area of the right hand side to even up the discolouration.

Are the down pipes double skinned to actually prevent dis-colouration?

Hi Bonzo,

Thanks for your feedback.

I was just looking at Blade Triumph at Cheltenham's webpage, on their s/h bikes for sale page is a Thruxton 12 with exactly the same issue.......and others on this Forum have made exactly the same observation.....left blueing/bronzing while the right is virtually colour free.....

....this clearly is a generic effect and not just a few random events.

I want both my headers to colour up......I love that look....at the moment it just looks odd.

I have just sent a mail to the Factory Warranty Dept. outlining this situation inviting their views and explanation of why this is happening and asking how I can get both pipes colouring up evenly.

Cheers,

Hi Bonzo,

I suspect I'm a few miles behind you......I bought the bike in late November with only 540 miles on the clock.....and sadly it's mainly been in hibernation since then avoiding salt!......it's just nudging 800 mile now.....I got a good ride in last Monday......God!, I needed that, getting 'cabin fever'......roll on some decent riding weather.

I'll share whatever feedback I get from the Factory.

Cheers,

Hi Bonzo,

This is the address I use, I wrote last night to the Factory at 9pm and I had an acknowledgement and a case number back by 9:30pm!....

[email protected]

I always mark my mails with: FAO Pete

Pete has helped me several times already and he seems to be right on the case.

Perhaps if every member on here with the same issue wrote in the Factory we'd maybe get answers at a minimum or even a resolution at best.......it'd only take a minute to bang an email to them, I titled my mail as
'Header discolouration'.....if everybody titled theirs the same they'd get the drift PDQ something was afoot!


Cheers,

OK, here is the reply from Pete who works in the Warranty Dept. at the Factory:



Dear Mr dickydido,

Thank you for your email enquiry.

This concern is not something that has been raised with the Factory, nor has there been any concern with any of our press fleet Thruxtons.

The header pipes on this model are not double skinned, nor would we recommend using an outside influence to change the colouration of them, in time they will probably match each other.

Thank you once more for your email, we hope you will continue to enjoy riding your Thruxton.

Best regards
Peter Clarke



So, it appears we on this Forum are the only folk who have noticed this colouration inbalance!........

Guys, if you have this same situation and you are not happy about it please take the time to tell the Factory, just drop them a quick email, email address is shown in the post above this one.......

....probably no one has complained because nobody reporting on the test fleet has paid their own hard earned cash for the bikes they are thrashing around on.......indeed the colour has no impact on performance but for me, it has a big impact on pride and satisfaction of ownership.......and like you, I paid a lot of money to get that so I'd like it right.

I notice there was no response to my request to know why there are different colours......if the pipes are not double skinned the difference in header pipe colouration is more worrying.......a single skin pipe will show up different cylinder temperatures much quicker and that results from different or inbalanced mixture burning in each cylinder......usually a weaker mixture burns hotter.....too weak and it leads to holes in pistons!!!.....eeek!

Cheers,

Hi Bonzo,

....thanks for the pics.......you can clearly see the left to right differential in colouring......again left more coloured that the right.

I look thro' You Tube for Thruxton tests........and in all of them that shows left and right views of the bikes the left side exhausts are ALWAYS more coloured up than the right......this cannot be a coincidence, there has got to be a reason for this trend, too many examples to just be an odd one off....got to be some kind of set up characteristic.

I encourage everybody on the Forum with the same variation in exhaust colouration to drop a line to Pete in the Warranty Dept.....you can find the email address in an earlier thread on this post.........and tell him there is an issue with your bike....
.......with enough input from disgruntled owners they gotta look into it......the bike goes great but the variation worries me 'cus more colour = hotter running.......plus I want both sides looking equally blued.

Thank you to everybody for their support with this.

Cheers,

dickydido
