The S4 has the same engine as the ST4. Funny how things can end up so differently, with just a few changes. I'd like to see what you get with the heads, different cam timing, 1mm squish, and a new map. Post back when you make changes, and I'll do the same.

true it's essentially the same engine, but the mapping must be fairly different between the two bikes. the st4 comes standard with 45mm headers vs s4's 40mm. also, tom's running the "corse" ecu (right, tom?) appropriate for the hot cams. so settings vary even more.
