Ok all you 600RR riders. I need more HP but not crazy HP. I know, I know, if you want more HP then buy a CBR1000. That's not what I want. I like the 600 nimbleness on the track and this is my 2015 RR track bike. I currently have removed the cat and added a shorty pipe and a Akrapovic muffler and removed the inner part of the muffler out. I flashed the ECU running VP T-4 fuel and all I get out of it is 100.6 HP. I want a solid 115 out of this engine. My first question has anyone done any engine mods like remove the head gasket and install a .018 thinner gasket? what about cleaning up the intake runners removing the factory slag and gasket match both intake and exhaust openings. How about a 3 angle valve job. If I do these will I get the 114HP? I know you can drop thousands of bucks into the engine and get 125HP Moto 2 but that is ridiculous you might as well buy the liter bike and drop more into lighter components. I don't mind spending 3,000.00 to acquire it. Any real help who has experience doing this please help.
