I am looking to buy an intake system for my banshee. I was wondering what other people are using and how they like it. I have heard good things about www.1dirracing.com and there G3 system but I personaly have never seen the setup on a banshee.

Any information

Thanks

i have the trinity stage 4 and i like it. very easy to tune with 1 carb and i only have to change 1 jet. plus with a clamp on filter it makes alot more room in the frame. very easy to work on and it also comes polished.

I have been thinking about going that way does it really add a lot of low end power? Right now my banshee with just the Toomey's is very fast but has no low end I need to floor it off the line to get it to go. But its a catch 22 if I gas it to much then I hit the 1st gear powerband and the thing is all out of control. I put a set of Razr II's on my banshee and the thing hooks up like crazy.

I think I am going to go with the 1dirracing G3 Power Reeds and the trinity 2-1 carb. I really need to add some low end. What pipes do you have on your banshee?? Have you port and polished the motor?

I have heard that trinity 2 in 1 is a waste of money because if you put 2 smaller carburator it will do the same thing, but im not sure of that but it seem logical...

Actually the true logic is when you have 2 carbs, only one is feeding the motor at a time because one piston goes up while the other goes down. So basicly you get a 35mm Carb that is working constant. This is how I understand it

yeah banshee i believe that you are right about the one carb working overtime. i've never really ridden a banshee without this setup. i'll be able to let you know in about a week when my other banshee engine get here. it's a dual 28mm mikuni setup that i believe is stock but it does have the 2 into1 tommey filter setup and the carbs i believe are jetted to tommey specs. but anyway i got the complete engine including kicker and shifter for 600 running ans 65 for shipping. i've beeen jumping for joy for 3 days now. damn 1 step closer to having the quads done. then it's suicide trike time.

my freind had a fast she with the stage 4 single 35mm carb ,it was impresive for a 35 mm .the cv thoery definalty works for the most part. it had a very pronounced hit
with fattys and no porting ,a quick bike and for his motor it really worked nice. problem is when you port the jugs your 35mm cant feed them enough fuel fast enough for the next stroke . according to most engine gurus anytime you lower the cfm of your intake you will have a mellow lower powerband and less horsepower potential,with that being said it isnt the best setup on parrallel twin ported cylinders.i really like my 30 mm keihin d slides it took forever to jet these bastards though but its a huge improvemnet over the bored and polished stockerswith vitos jet kit i used to have.its instant throttle response and instant powerband right off idle .

no keeping the bore small keeps torque feeding the 40 into each cylinder may give tha tup and pretty much defeat the purpose and its still not the cfm of even 2 stockers. thers a thoery on how in high rpm and hp motors a single wont flow due to
something about the reeds and the back fuel/air charge phenomina that happens on a single setup. i could tell on my motor tahtthe stockers( even when jetted rich)werent giving them (jugs)enough air/ fuel,once i went with the bigger carbs it quit that cutting out sensation and opened up on top alot better

Its really hard for a single crab to feed a multi cyl motor Like the banshee efficiently at higher RPMs. The change in flow direction is so constant and erratic that it will starve the motor and produce a lazy top end the single carb is awsom for a strong bottom end pull but tend to lighten up the potental hp on the top. A snowmobile motor is a totaly differant port configuration and tends to run in the low to mid of its Rpm range most of the time so a single carb set up is perfect for this kind of power curve..

Well since we dragged this thread up I went with a set of Mikuni Carbs and the G3 setup. Works great improved the low end a little and made the top end crazy.

I have the Trinity 35mm 2 into 1 and it makes killer low end. I think it is great for a woods rider. Mine stills does ok on the top, just not as good as if it had 2 bigger carbs.

Sounds like you may want to trade fora Trinity Stage IV with dual 35mm set-up... :evil3:
