bansheejoel Posted March 15, 2008 Report Posted March 15, 2008 my cousin took his cylinders off of his banshee and is going to have them ported, the guy doing it said hes going to raise the exhaust port 2.5mm and taper the bridge port and raise the intake port....does this sound about right to anyone? thanks Quote

Wildcardracing Posted March 16, 2008 Report Posted March 16, 2008 Sounds kinda half assed to me, what about the transfer ports and boost port??? I would first recommend that he send them to a reputable builder. Second, the tranfer ports need to be raised some to correct the transfer blowdown (something I'm still playing with). I have had the best luck reshaping the intake, not enlarging or raising the intake windows. The goal is to flow more air without decreasing intake velocity. The exhaust can also be widened. Raising the exhaust 2.5 mm sound like an aggressive trail type port to me. What type of riding does he generally do and what pipes is he planning on running as this will make a difference in what exhaust duration to run. Best bet is to talk to some of the experts on here: KEVSWS6, F.A.S.T, FLOTEK, Passion ect. These guys will steer you in the right direction and who knows, you might find a better price on a better port job. Just my $.02 Quote
bansheejoel Posted March 17, 2008 Author Report Posted March 17, 2008 he said he charges $150, he will be riding dunes/trails. Is it possiable to make the bridge between the two intake ports to small? if so what will it do? the way he is describing it he will be making the bridge tapered as well as narrowed. raising the exhaust port, raising the intake port a little bit and i think thats it...they've been in buisness for 35+ years so i hope he knows what hes doing. lol. let me know what you guys think. thanks mr. avery and blowit for the input Quote
