I am purshasing an 06 ultra. I have two builds I am contemplating. The primary one is the axtell 97'' kit, with cylinders and forged pistons, woods tw5g cam, heads done by Jim at Megaflow, SERT, SE air cleaner, SE quick install push rods, and some kind of exhaust, hooker, t-rex, rinehart, or SEII slipons. The alternate build would be, stock heads just cleaned up by Jim at megaflow, stock cylinders torque plate bored to 95'', SE flat tops, andrews tw26g cam, SERT,SE air cleaner, SE quik install push rods, and SEII slip ons. Wat would be the best build for two up riding, 75% of the time, in the 2-4000 rpm range?
