I did a search and it seems most of the head/cam upgrades are on Gen 1's or 1397 mods. I was wondering what I can expect from a Gen II with just heads and a cam? I want the bike to be very rideable, that's why I'm not looking for huge power or drag style power curves. I want it smooth and progressive and I don't think beyond 250 hp without TC. Don't know how serious I am yet - still looking at cost and results.
