I have a 4 mill stroker crank, 68mm bore, a cool head with 24cc domes, v-force reeds, the 35mm trinity stage IV two into 1 carb kit, and CPI's. Before i got to cpi's i have fmf pipes and it ran pretty good, now that i put the cpi's on it isnt runnin to swell. I tried re-jettin and nothin is working so far,but i only had two sets of jets to work with. It starts and idles just fine and even is ok in mid range but it doesnt like to go into ban and when it does it will kinda go in and out and sputter. I ride at about 1000 feet above sea level and the weather is about 70-80 degrees. Any suggestions would be greatly appricieated ! BTW, when the engine is running if i touch the spark plug boot on the right side it shocks the crap outa me ! Wasnt sure if that had anything to do about it.
