Son of a %^&#@ !!! Here it is again, as one noble member just pointed out, the temporary need for speed. Isn't that why we bought a H-D that comes already at 103 C.I. I own a 2003 SE RK, and the MAIN reason I bought it was the 103. Period. Then my addiction had to build from that. I changed the heads, and finally settled on a .625 lift cam to boot. I remember inquiring with my "mechanic" at the local H-D shop and was told that the switch from fuel injection to carburation to be able to utilize a larger TB and alleged fuel flow increase was not worth the costs involved. I would have; believe me. He then stated that besides, the capacity on the SE versions are different {bigger} than the stock TB. D-h-h-h-h! So now am I missing something here? Feel lost, as I pretty much have maxed my engine out without making a hand-grenade. Are you guys talking about re-working the injection manifold? Or actually getting a different (I need to know the part number) Throttle Body? The throttle body in my engine is part #27603-01, and I assume that the subsequent years are the same...Boy if there's more power to be gotten, I can get excited (again).
