Does anyone have experience with head porting? I understand the principals and theory behind it, just is it that benificial on a sixxer. I've got some friends who owe me BIG. The guy who would be porting is very well known and great at it. I just don't want to loose what bottom end it has for 5hp @ 13000. Does anyone have dyno results, before and after? Thanks Tony

i did a very mild cleanup on my gsxr 1000.with the valves out you can see strait threw to the ground so there isnt a lot meat to hog out. i dyno everything i do but i milled the head at the same time i ported so i cant give you exact numbers , but i can tell you im not dissapointed with the bottom end thats for sure
