Heres what my banshee has before i ask my question, t- force5 pipe ,trinity2-1 intake pwk 35mm,lightened flywheel,noss machine head 19cc domes v force 3 cascade reed holder= larger opening than stock v force, 14-42 gearing im about 220 lbs, when i went from stock carbs to the single it seems like i lost a little top end but got gotso much power everywhere else and is so much more fun to ride especially in pismo where i mostly ride, i love the powerband now its not so violent and the bike feels just as fast if not a little faster i just have to shift sooner. im a duner and trail rider , but i like drag racing and i just want to go faster with the combo i have now,id like a 4 mill, would it be a waist to get my cyls ported and a stroker crank if i keep the single carb setup, would the difference in power be minnimal? could i just get a mild dune port or is there such a thing as an aggressive woods port, i dont mind losing a little bottom end but i would like to feel a huge difference in powere and maybe make it about 3 bike lenghts faster, who does the best porting for a 2-1? also when i went to glamis with the mods listed except for stock carbs my bike wouldnt pull 4th up the steep side, would porting solve this?any help or comments positive or negative is appreciated thanks.
