I just installed a Dr. D slip on and a Dobeck and have the settings at 4:30, 7, 4, 7. The problem is that the part around the electrode is still white as hell. I have ridden it for about a total of two hours since the install is this a bad thing. I have done a good amount of riding throughout the RPM range. Will two hours or running lean do a lot of damage to the motor. All I have is the slip on, no intake and the lid is still on. Any information will help thanks.
