I have a question for you. My friend has a Raptor running 146/148 dynojets, 12 uni vents in the lid, 12 disc e-series. It ran verry well. As a test, he removed the uni vents, and added 2 discs to the e series. He wanted to see if it would lean out or run better. Well, it ran fine but now he has black carbon all over his 6 pack rack and cooler. Wouldn't a rich condition do this?? [img]i/expressions/face-icon-small-confused.gif[/img]
