I've had my Two Brothers Exhaust (M7) and Dynojet kit installed by the dealership on my bike for a couple of months now. I've noticed that my turn signal (by the exahust) is now "tinted" from, I guess, black smoke or soot.

My re-jet is with the 128 main jet and stock 35 pilot jet. This set-up came directly from TBR -- what they recommended.

Prior to the exhaust and re-jet my bike would stutter, at start up, from 2k-3k RPMs until the bike had been ridden for about a mile. After that no issues.

Since the re-jet, I don't get that any more and the bike starts up and runs like a champ.

But now I have this tinted turn signal from the exhaust.

I will note that it's been hot here in central Florida for the quite a while.

Is this is an indication the bike is running too rich now?

Any thoughts/recommendations before I go back to the dealership for a check on this?

Thanks.

Mine turned 'black' with the Two Bros. as well.

Most of it will come off with some de-greaser like 409 or Orange cleaner and some elbow grease.

 

Cool, thanks for the tip.

 

Happens with all pipes...My FMF did that till I got some small blinkers up out of the way

 

If your bike runs well your fine.

 

Tried 409 multi-purpose cleaner this weekend. Worked like a charm.

Thanks again for the tip.
