Default Reading Evo - Spark plugs

While I am waiting on my cam I have another question.
I pulled the plugs on my bike and the Front plug is damp and black -
my rear plug is dry and white/brown which I think is nomal operating range.
The bike has a Crane Cams HI-4E adjustable Ignition module W/ rev limit adjustement. It allows adjustments to the front and rear cylinders along with a rev limit adjuster. Any ideas on where to set the front and rear cylinder adjusters at?
I believe the choices are 1 through 7 or 9 for each.
I have noticed when working on the bike after a idle Warm Up, that the front muffler was always cooler than the rear muffler.
