Night and day, I want to say. But I am basing this on my app. I done a rebuild and changed to pt mid pipes cool head 17 domes and a fresh bore. What kind of power do you use? This set up makes monster power on the low end, may have lost a little bit on the top. Doing some jetting now, so I cant be shure. I will check back

They dont make monster power on the bottom end compared to a good set of twin carbs. The difference on the bottom will be un-noticeable. However, you lose quite a bit of topend. Buy a set of 28mm flatslides, it will cost about the same and make more power.

i need stock carbs so i dont have to race in the open class

ditch that 2 into 1 bullshit. 2 carbs are better than one for a banshee anyway.

Well like I said i am basing this off alot of factors. It may have been the pipes (pt mids) I am not a duner. Just hill and trail. I dont use the 9k rps Trinity has been at the shee's a long time so I would think they done all the dyno work for us. I dont have to worry about carb timing or jetting two at a time. Or the lean on one side problem that alot of shee's come across. I am happy with my set up. Clutch gave out before I have the jetting tuned in. I will let you know when clutch parts arive.

i noticed allot of gain in bottom but i did lose some top

ive also had the wrong jets i my stock carbs

i would say stick with two cards it gives you way for power on the top end. if you want low end go buy a 4-stroke.

that polish snoop dog was the man on here pushing 2 into 1 pipes and carbs. Why the change of heart? Like I said I wanted the constant vel 2 into 1 carbs to make the low end power. I think that it does help. I have a real nice set of flat sides that are in the box and thats where I intend to leave them. I dont dune so I have no need to use the 9k 10k rpm for tight trails and coal hils we have in ohio It seamed to do well. BUT as I posted I didnt get alot of seat time due to the clutch. I changed to a pt mid pipe, that may have made the power. I have a set of fattys that Im going to try. Ill let you know.

Carbs dont really determine max rpm hp limits. Its pipes and porting more than anything. I haven't been much of an advocate for twin pipes or carbs for more than a year now. I run pro circuits, and twin 28mm mikuni flatslide carbs now. My redline is 8,650 rpm, and its a dune bike. Just because you ride trails doesn't make you a canidate for a 2 into 1 pipe or carb setup. Do a search, I posted some dyno results from last winter on the comparison from 2 carbs to 1. You lose about 5 hp on the top, and only gain about 1 hp on the bottom with the 2 into 1 setup.

Totally not true... I noticed a big difference down low and up high. One of the best decisions I have made. Just wish I would have done it sooner... A lot easier to tune and a lot easier on the thumb when riding those long days.

Totally is TRUE, I have several dyno sheets to prove it, and I have 2 banshees + my own that I have converted back to twin carbs and the owners are verry happy. Going from stock carbs to a 2 into 1 intake you will notice more power from a 2 into 1. Going from a 2 into 1 intake to a set of 28mm flatslides you will notice no difference in bottom end, and you will notice a huge gain in midrange and topend power. You guys are wasting your time with single carb setups. In most cases you can buy twin carbs with air filters and a cable for less than one of those single carb kits.

I wonder if I've been waisting time? I paid 350 for a 2:1 trinity and it's done all it's supposed too. Right now I really feel like trying some OTO 28mm opened up for about half what I have in my trinity setup. I will say that dialed it, my bike is either slipping the clutch (ebc upgrade all 6 springs) or spining the tires in the wheels (asphalt only). I don't have similar symptoms when the tires can spin. It makes very decent power!!! I wonder if I'll use the extra power or just bust a clutch basket? Marcus

Just because yours didnt make power doesnt mean someone elses combo wont. Dyno sheets don't prove individual parts. I went from the 2 26mm carbs what have been gone through dozens of times. I then installed 33mm carbs and it ran like crap. So I decided on the 2 into 1 with a 38mm and it runs like it has never ran before.

 

No matter how much you swear it does or doesn't it is all opinions!!!!

[dewey4390]

what pipes do you guys run? Im running pt mids.
