1quickshee Posted January 20, 2009 Report Share Posted January 20, 2009 Well now that i got a little of money to put in to my toys Its time to open the motor up on the sheeeeee Lmk what you guys think. My banshee is a virgin not motor port no bore noting. My current mods are, CPIs, Vforce reeds and a K&N intake. I want to stay stock carbs and with the air box (stockieeee look ) Now should i go a full drag port or a mild, i'm planning on putting a stroker but later on. I know you cant go drag then put a stroker because you got to re port it, and after a full port it cant be done.(correct me if im wrong) I'm also planning on shaving the heads, and changing the pistons. I also have the choice of either staying with 93 octane or switching over to AV which they said i can gain 2 or 3 mph any suggestions would be greatttt Quote Link to comment Share on other sites More sharing options...
kbone77 Posted January 20, 2009 Report Share Posted January 20, 2009 Have to ask the default questions-What kind of riding do you do? Porting will be determined by what you're doing w/ the bike...drags, trails, desert, track, etc.. My opinion is to do things slowly-and not introduce alot of different mods at once-that can leave you dumb founded if things don't end up working right. For example if you get a new head, crank, pistons-and then you can't figure out why your compression is too low/high-you can have a combination of several issues. If she's virgin a good port and milled head will be a big difference.. i had cpi's, stock carbs, a mild port, and milled head for 4 seasons and was very happy w/ it in the dunes..

1quickshee Posted January 20, 2009 Author Report Share Posted January 20, 2009 Well, I do mostly drags i guess you can say, maybe a little trail but not deep woods type. I thought it would be better to have everything done at once? I'm planning on staying with the stock head also. Quote Link to comment Share on other sites More sharing options...
kbone77 Posted January 20, 2009 Report Share Posted January 20, 2009 The milled stock head is a no brainer, it's cheap and effective. If you still plan on dune/desert riding, a full drag port job may be a little extreme, but just my opinion. I've had alot of friends who had to be the fastest-then realized after big$$-the fastest drag bikes aren't very fun to ride anywhere but on the drags.. Milled head and mild to medium port job will give you a the biggest noticable increase. Then you may want to install a timing advance plate, and make sure to dial in the jetting as you go. When I installed a 4mm stroker, I didn't require any more porting, per LA Sleeve anyway. Teh mild was fine, they just cleaned it up. Technically a stroker will draw in more air thru the same ports..

kbone77 Posted January 20, 2009 Report Share Posted January 20, 2009 the type of gas will be determined byt he compression you have, I see alot of people use 160psi as a rule of thumb. anything over should start mixing in race gas.. simply using different octane on the same motor doesn't make more power...
