first thing, the main thing i want to know after cams degreed, cranked and run thru few heat cycles is compression. verifies basic engine build/cam degree is good and hp to be made. making hp thru the powerband is all about cylinder pressure. just did a basic clean up, .025 mill, cnc valve job on 07 gsxr 1000, bike came in making 155 lbs, no great power to be made there no matter what u do. fired up and run in a few times with cams just bolted back in, stk hg, compression now just over 200. 30% increase, like too see 190 min on street engine. cranking compression main indicator of torque/hp available finished up correctley. zx14's/busa bigger motors i can squeeze 220-230 out of them on stk pistons with adequate ptv. makes crazy torque/hp for accleration.
