Holy moses


Fast shipping and the orders being correct is enough to keep me as a customer, I recently purchased the holy moses air filter ,adapter and .615 carb.It produced the best power of anything I have tried.Where I'm running in to problems is when I'm testing other stuff on the dyno and warming motors up it fouls the plugs.From reading the instructions I know this is to be expected.Can i lean the motor on the idle jet or do you have a ''dyno only'' carb like your break in carb etc... This is a dyno only problem.
I thought the fouling plug issues went away once you took the restrictor plates out? Do they still keep the idle side so rich for power down low and takeoffs?
