ok i recently well finally started riding this bike on the dirt drag and of course it has not enough power to beat the other guys im only guy with a honda...but everyone else is using a suzuki what weird they take a 600 block and put a 750 head on it....now i was wondering if i could do the same to my 600 block....also i have a nitrous kit but not going to install yet...looking to do motor upgrades before i go nitrous...any comments will help thank you

 

i imagine a 750 head flows better, problem is honda doesnt have a cbr 750.
