    Exhaust Pipe Color

    Bike 02 1150 GS. One pipe is a darker shade of blue then other. Is that a tuning issue? Throttle bodes are balanced.

    Get the bike warmed up with it running take a lazer temperature gun and compare the readings on both sides. If they aren't close you might have a problem to address. Jon

    I would probably remove the spark plugs from both sides and compare color and maybe take note of any traces of metallic looking deposits on the plugs. If the plugs looked about the same then I probably wouldn't get too concerned. How does it run? Does it start good, idle smoothly, go down the road without surging? In short do you notice any other strange behavior besides head pipe color difference?

    On all the boxers one cylinder sits slightly ahead of the other.

    For the most part this means the pipes don't have the same bend. (There are none interchangeable left to right and vice versa).

    Not a lot of expectation should occur, then, for the individual pipes to discolor identically.
