Default Re: I think I need help. Bike Running too rich?

The brown on the plug where the oil has burned off seems to be the right color, one way to check if its rich is to do a test run without the air cleaner on. If it runs better it is probably rich and needing more air or less jet size, but don't run it without the air cleaner for long.
Your results may not be the same,Greg
