Odd smell from King Pin
On occasion, when I first start my motorcycle or when it is idling, I can smell an unpleasant odor that smells a lot like a fart. The smell lasts for 30 seconds or so and then goes away. It will also go away immediately if I rev the motor.
I run 93 octane in the tank and it doesn't appear to make any difference what brand fuel that I am running.
Any idea what to check or does anyone else experience this/is it normal?
