my one bike seems to be a bit of a slug well i guess it goes not bad but not how i feel it should. i actually bought this one the way it is so maybe the combo of parts is whats holding it back. it is a stock stroke welded crank with a set of ct racing monoblock big bore jugs 73mm i contacted them and there records show they did an aggressive dune port. has 180psi of compression running it at +4 on the timing, has a set of bb shearer inframes, has aluminum intakes, v-force reeds, and a pair of 38mm pwk air strykers on it with 180 mains plug chops show the jetting is bang on it runs good just doesn't seem to put the power out i feel it should i can only beat my buddies 700 raptor piped chipped intake by about a bike length and i am a competent rider. i feel this bike should walk all over him. oh ya and i am running 110vp in it with castor 927. any advice would be great.
