sredish Posted September 17, 2007 Report Share Posted September 17, 2007 (edited) i have a trinity single carb on mine and it runs awesome in the dunes along with everywhere else. the single carb does not make one cylinder run leaner. 400rednEX, how long ago did you get your Gorr port? I know he was MIA for awhile (in UK or something) but wondering if you got yours after or before the hiatus.

Who the hell came up with the one cylinder leaner thing? Thats impossible! Quote Link to comment Share on other sites More sharing options...
sredish Posted September 17, 2007 Report Share Posted September 17, 2007 (edited) Only way it's possible is if you don't have proper synchronization between the cylinders, like if the crossover tube is left off. the crossover tube is pretty important on the 2-1 carb setup and if your not getting equal balance there, one cylinder can draw more than the other if its not balanced and then produce a "hotter" side. in an extreme case of this, one cylinder would be firing fine and the other misfiring, resulting in a super hot side and an ice cold side. i've seen it myself so it can happen but a "properly" setup motor/carb deal should not experience this, if they do there's a problem.

Snopczynski Posted September 18, 2007 Report Share Posted September 18, 2007 You dont run a crossover tube on a 2 into 1. Its the same intake manifold for both cylinders. So, there isn't a way for the 2 into 1 to inherently run one cylinder leaner than the other. Quote Link to comment Share on other sites More sharing options...

Hmm.. I thought the 2 into 1 eliminates the crossover! I never seen a crossover tube on a trinity, cascade or graydon 2 into 1 intake.

sredish Posted September 18, 2007 Report Share Posted September 18, 2007 (edited) check inside the trinity manifold, it's internal. it doesn't have to be a "tube", just a port or something to allow the two sides to equalize. the graydon doesn't have one and that can cause issues, when I fabbed one on my Graydon it ran awesome, better than the Trinity manifold. edit: i've never seen the cascade manifold, but I'd love to. i've actually never heard of it until recently, haven't been on the bhq boards for awhile. if anyone has a pic or link, I'd sure love one.

sredish Posted September 18, 2007 Report Share Posted September 18, 2007 (edited) here's my graydon, w/o the tube. the right side wanted to misfire. so I took it off, welded two small ports on it and then used a 3/8" tube for a crossover. it ran totally awesome after that. i liked it much better than the Trinity and with the PT Hi Revs (changed from the T5s not long after this pic) and killer portwork, it was an unbelievable runner. the airstryker Keihin models are very worthwhile on a single carb setup as well. the way the airstryker works helps out a lot with the low rpm vacuum issues and it does work. what a nice carb.

Snopczynski Posted September 18, 2007 Report Share Posted September 18, 2007 None of the two into 1 intakes come with a crossover tube. I have a trinity on my bike and a cascade on my cousins, uncles, best friends, and my best friens dad's bike, neither intake has it. The equalizer tubes only come on twin carb setups. You dont need to equilize a single carb intake, both cylinders pull the fuel and air mixture from the same place in front of the carb where it dumps into the intake.

letsgetthisdone Posted September 18, 2007 Report Share Posted September 18, 2007 (edited) then explain to me why, when i put dual carbs back on it, the cylinders ran the same with the same jets in both carbs....and no, there were no airleaks..

sredish Posted September 18, 2007 Report Share Posted September 18, 2007 (edited) pull the trinity and look inside, you'll see an equalizer port. not sure on the cascade never seen one. and i said on the graydon, there are quite a few that run better when modded with an equalizer tube. Also, again I'll say if anyone has a link or picture of a cascade, I'd LOVE to see one, never seen one. no need to start a pissing match here, i'm not saying you all are wrong or right just bringing some things you all may have not thought about. as far as "letsgetthisdone", what manifold were you running, Trinity? there are some quirks of a single carb, mostly due to vacuum and not knowing a single thing about your bike and your problem, i can't really give you an answer but it probably had to do with a combination of vacuum differences between the cylinders and needle specs and who knows what....

Snopczynski Posted September 18, 2007 Report Share Posted September 18, 2007 Ok, I did. Nothing on the left, nothing on the right, and nothing in the middle. Sorry, no crossover equalizer tube in a trinity cv intake. I stuck my inspection mirror all the way in and felt around with my finger. There is no need for a crossover balance tube in a single carb intake. It will equalize in the giant open space shown here in the first picture, right behind were the carb goes.

wesw Posted September 18, 2007 Report Share Posted September 18, 2007 personally i wouldnt own a set of airstrikers, they run way whacked jetting compared to pwk, the slides are different. its hard to compare jetting with other cause their isnt many running them. i know 91 banshee had a bitch of a time getting them to run on his cub. had to run beyond small jets and lean needle, clips. just my opinion.

Snopczynski Posted September 18, 2007 Report Share Posted September 18, 2007 You also keep talking about low vacuum issues. I, nor anyone else I know with this intake has never had any idle or vac. issues with this setup. Because the carb feeds both cylinders, it has constant vacuum being pulled on it while running. That's why trinity calls it a constant velocity intake manifold. We just put in the right size pilot jet, start the bike and adjust the idle screw.

400rednEX Posted September 18, 2007 Report Share Posted September 18, 2007 sredish, i got my gorr porting a few months before he stopped taking orders and closed up shop to go to europe. it didnt seem too impressive until i replaced my 33mm single with the 38mm airstryker i have on it now. it gained power everywhere and really came alive. my trinity intake looks just like the one in snopczynski's pics. ive had it off several times and there are no crossover ports in it anywhere, just a plenum that splits into a left and right runner. maybe there was a different version at one time though.

sredish Posted September 18, 2007 Report Share Posted September 18, 2007 hmmm, you got me then. they did have a few different variations as they "evolved" but i have no answer there. Mine had a little port in it, i could just barely get my pinky through it to the other side. as far as Gorr's port. I had him do a set of Banshee cylinders for me and it was an insane port job. i had good power from bottom to top and revved out really well, I was pleased with it. I was just hoping to see that he was back in business here in the states. Quote Link to comment Share on other sites More sharing options...
