Banshee MX/GNCC Build

[Suz_Madness]

Ok so im about to graduate from the Powersport Institute in Cleveland and am looking at a build for a friend who wants the work done......

He wants to race his banshee mx and a gncc race once in awhile, what should he put into it for best performance, i was thinking port, carbs, pipes, and a head of some sort and maybe a big bore kit? Any you guys out there wanna throw me an opinion please do thanks he is also starting with just a stock shee

wants a MX banshee huh... first step... buy a outlaw chassis and start form there... they are the chassis with the 250R suspension and they use a banshee engine and plastic... stock framed shees are not MX bikes... they push badly in corners..

well, mx and gncc are two very different types of racing. like for example, in mx its preferred to have your bike as wide as possible with wider a-arms/axle, etc............but for gncc its better to have a stock width bike to get through the tighter spots in the woods. i'd say it might be kind of impractical to setup a banshee as both a woods racer and a motocrosser.

ok so now that the chassis issue is set up, how about engine wise? any decent ideas like i said before carbs, pipes, head, and port work and possibly big bore options, how would a stroker crank do anyone ever seen it on a track or is that something to only consider on the dunes?

[370banshee]

like KY said gonna be hard to set it up for both... oh yeah and set aside a few grand for that chassis... if you can actually find one..

well for the motor a good trail/mx port would do you good along with a 2 into 1 carb, lowend pipes, cool head, +4 timing and some other little goodies and you'd have a killer mx/ trail bike.

I think you would have more luck building it into a cross country/woods machine.
I would really think about the geometry setup before you dig into the engine, If you dont want to do the frame (which is understandable because there so much money) I would spend some time & money into the suspention.
Also you might want some better A-arms & think about a -1 swingarm.

yep... -1, or -2 swinger, for mx. maybe stock length for gnnc... at least thats what i would do... like everyone else said.... cant set a banshee up do both things competitively. not with out, rebuilding it before each race..... kinda gota make a decision between one or the other..... unless he doesnt want to be competitive, like he is in it for the love of riding, and not winning? is that a possibility?

i would say either a 403 national pv kit fron duncan racing
or a 409 pv kit from esr
maybe some high rev pipes or midranges
lets see deff long travel suspension -1 or -2 swinger
port work carb thats all i can think of atm
