single carb vs. dual carb

[Snopczynski]

Yeah, I dont know what happened with this dude and K&T, but, Every one I have ridden or seen has been fast as shit.

oh no. you didnt just go there.... :ohmy:

he is right the banshee engineers built it with two carbs, changing and putting 1 carb on it messes the whole bike up, that is why some people wonder why the single setup is so hard to setup, cause it wasnt meant for one carb, so get a 250r or a 4 stroke

idk how much more tq a single carb might have. but all i do is woods riding and recreational trails on occasion. i got dual 30mm carbs. and i love it for what i do. who needs alot of tq anyway? thats what the clutch is for.

But when u do get it tuned and diled in it runs awesome. theres no lag or that annoying blubber in the bottom end. I think its snappier and yes definantly has more torqe. I like it in the trees and hill climbs just for that reason. And you get way better fuel milage! LOL! :yelrotflmao:

The torque gain is pretty minimal, its the acceleration speed that increases and gets most people excited. Howeve, it whacks quite a bit of power off the top end. I have a fairly low revving rpm motor. I peak at 8,750 rpm give or take 50rpm. My hp difference between twins and a single at that rpm was 4.74 hp. That was about a 7.5% gain going to twin carbs, and I didn't notice any change in the bottom end power. It definitely pulls harder on the top now though.

i tend to disagree with this.. just because the bike was designed with 2 carbs does not mean a single carb will not perform well for someone.. for example: we change the port durations which alters the stock design, we alter the ignition timing with good results also.. are you going to leave your stock pipes on your banshee just because yamaha designed them?? i think not.. these bikes get heavily modified in many ways.. it basically boils down to the bike being PURPOSE built which a lot of people forget about.. its always DRAG DRAG DRAG.. prople get stuck on this nad forget that their are a lot of people that ride their quads in the woods, moutains, MX. etc... not being a smartass.. just proving a point of view.

Thanks for all the feedback guys it came with the 2 into 1 when i bought it i prob would still have duals if it was up to me because i priced the kit and i prob wouldn't have bought it.....and i do a little bit of both i'm not balls to the wall drag racing but when i go to busco beach it kinda turns into that....but if i keep it in the power band on take off the bottom end tq is endless

You can also change your gearing to compinsate for the slight loss of topend.
