Need advice about 2-1 carbs

[Ozzykarlberg]

I have a 2002 banshee have rebuilt 2 times and I hatethe twin carbs. Its now bored 30 over, aftermarket pipes, and I am now needing to bore it again Ill either go 40 or 50 over. I was really wanting to go to a single carb. I was just wanting to know which carb would be the better one to go with. What size i would have to go with. And if anyone has one to get rid of let me know.

I'm confused...

 

are you looking for a new carb so you don't have to rebuild as often?

If so...I'd look further to get to the real problem....

 

If you're looking for a single carb setup for ease of jetting, ease of use, etc., then...it'd be a good idea.

 

Depending on what you want to do...a single carb might not give you the performance you're looking for.

 

They're great for low end, trails, etc. But, if you plan on duning, drag racing...twins are better.

 

If you're rebuilding that often, I"m thinking either it's not running right in the first place, or you're beating on it in dunes or racing...or both...

I think the 35MM carb is the only way to go. Even a lightly modded bike like yours will respond favorably to the 35. The 33 just limits your potential for future upgrades, and it will also limit your top end flow now. There are a couple of popular choices. The Trinity is a short runner design so it flows decent on the bottom and good on the top. The Proline has a longer runner design which on cars I know improves low end torque but limits flow on the top end. I haven't really ran in to anyone that has done a head to head match up so I have no way of knowing the actual effect on a Banshee. The good thing about the Proline carb is the cost. They always seem to go for 100 or so less than the Trinity 2-1. The C.V. carb setup helps everywhere I just don't know how much the runner length has to do with the rest of the performance envelope.

You hit it right on the head. I dont get around dune riding alot but I love my banshee. I just need more low end for riding trails, and im hopeing it might be easier to jet it, as far as rebuilding I dont have a clue what happened this time the bottom ring on the right side broke and tore the crap out of the piston. One more question will I have to get new pipes with a single carb?

The 2-1 is a great carb. More low end and mid for trails and as much or more top end than the stock carbs. Yes, you can use your current pipes (even tho we don't know which ones you have). I've ran then with Fatties, PT Mids and soon to be running it with T5s. It is much easier to tune and deal with, that's not why I have it, but it's a good side-effect. I just won't run 2 carbs.
