Mine is running a bit rich, so my exhaust pipe is turning a bit dark blue/black and now the dyna is doing the same in the middle.
So I have turned my air/fuel screw in one turn.... hopefully that will help.
your adjustment is the pilot screw or idling to low throttle.
the color happens from the cruising speed or mid throttle.
and blue to black is lean.
best you can do is gold.
I'd go 1 step higher with the main.
and there's nothing you can do about the muffler turning colors 'cept blu job
