Hi all-

I've got about 900 miles on my bonnie, and have noticed that the left pipe is nicely blued next to the engine, while the right pipe has only turned a light brown or tan. I did the 500 mile service myself, and have removed the AI and balanced the carbs (homemade loop manometer). Couldn't have done that work without the help of this great website! The carb balance was off quite a bit with the vacuum being too low on the right cylinder, but the pipe coloring hasn't really changed since the re-balance (400 miles ago).

Now I'm thinking the idle mixture may be off (too rich?) on the right cylinder, making it run relatively "cold"... if that makes sense to anyone? Is there anyway to adjust the mixture screw without having that special "D" screw tool? I've ordered that tool, but it won't be here for at least a week or so. My dealer is over an hour away and they're always busy, so I was hoping for a way to work on this over the long weekend.

Any thoughts would be greatly appreciated.

Thanks!

'They all do that sir' will be the Triumph dealers reply, but mine is the same, more blue on the left, don't know why?

If you didnt get the mech's hand print on apipe- you are doin good! Nobody seems to know why? They just d othat. My right now is rite on nice blue to gold past the 1st bend. The right is a little bluer w/ a nice imprint of the prep mech hand print- which wont come off!. O well? :???:

at least your not asking how to get rid of the blue.

(blue is good.)

How odd, my 2007 T100 also, left pipe a deeper golden hue than right, neither one really bluing up as I expected to see at 700 miles now.

Guys-
The uneven blueing is because of the way the coil is set up...one side gets a slightly hotter spark than the other, and yes "they all do it"...of you want to prove it, go swap the plug leads. It'll run fine no worries, and the other side will catch up.
