johnnyg1968 Posted May 4, 2005 Report Share Posted May 4, 2005 I have a trinity two to one on my banshee, and I am having trouble getting rid of the hesitation right above idle. I have a Noss head with 21cc domes, motofast pipe and silencer, I put a k&n filter in the airbox, and modified the lid with a filter skin kit so it could really breath. Right now I am running a 190 main, 55 pikot, and clip on the third notch of the needle. Trinity tech. advised to go to a bigger jet since I was running a 50 with the air screw at around 1 - 1.5 turns out, maybe even 2 and it was less but still there. they said I was to lean. the richer I got the worse it got. I am running 110 oct. fuel with klotz mix. I am at my wits end with this damn carb. I need help, and advise. please email me with some ideas. carb is a 35 pkw. j.goldsebrry@insightbb.com john Quote Link to comment Share on other sites More sharing options...

Did you try a 52, how about a 48? I don't know why you'd be way too lean with a motofast pipe and a 55 pilot, hell, I was on a 52 with my portwork and I was richer than most peeps there. Just relax and have patience, we'll get it. Quote Link to comment Share on other sites More sharing options...
fixitrod Posted May 4, 2005 Report Share Posted May 4, 2005 If it got worse then you need to go the other way for sure. You never know who's on the other end at trinity. Another thing you can do is see if you need a longer needle. Drop the needle down. It might mess up your throttle response, but if it fixes the of idle problem you could get the same taper and diameter needle ... just longer. You'd be suprised how much the needle effects the full range on a pwk. Quote Link to comment Share on other sites More sharing options...
theeechozen1 Posted May 4, 2005 Report Share Posted May 4, 2005 What needle are you running?? I would also stop running that 110 octane until you get the compression to support it. with 21cc domes you are good on pump gas all day. on a lower compression motor you will make more power with lower octane fuel.

Wallynut Posted May 5, 2005 Report Share Posted May 5, 2005 If you've read any of the previous posts concerning 2 into 1 setup, you will see that a good number of people have had great success changing out the needle. sredish, has mentioned www.carbparts.com, I used them and like how fast they ship and costs involved. $9-10 for a needle. If you do get a new needle, put it in at the same setting as the one your running now. I did that, and was surprised at the difference. I was having more a flat spot in the midrange, compared to you. It can be frustrating, but do you really want to go back to stock carbs? Good luck Quote Link to comment Share on other sites More sharing options...

Wallynut Posted May 5, 2005 Report Share Posted May 5, 2005 Your probably looking at a DEK, I bought a EEK and CEK. The EEK seems to be the needle of choice for most so far. Yea, it is hard to read, but it's there. I'm running a 48 pilot on mine, seems the pilot size varies for each person. Once we get some nicer temps(read more even temps), jetting should be easier.

sredish Posted May 5, 2005 Report Share Posted May 5, 2005 I doubt your gonna hurt much as far as lean/rich going from a 50 to a 48, so I'd try it if the 50 gets better. The pilot in that thing is so easy to get to, it's worth the time to try a 48, trust me. Also, get an EEK while your talking to them, and as Wally said, try it first in the same clip position, it'll make it run better, but probably won't do much for your starting as it changes mostly 3/4 to WOT.

johnnyg1968 Posted May 10, 2005 Author Report Share Posted May 10, 2005 Don't give up, just post some more about it. 365343[/snapback] I went to a 55 pilot and it seemed to work out a bit better, I got the air screw in to 3/4 to 1 turn out and it seems to like that the best. I also went up to a 195 main to see if that did anything, I really couldn't tell any difference with the acception of the plug turning darker faster. I also ordered a eek from carbparts.com. it should be here this week sometime. do these things have rev. limiters on them built into the cdi box???

Wallynut Posted May 11, 2005 Report Share Posted May 11, 2005 I don't believe that cdi has a rev limiter like the four stokes, theres just a limit to how many rpms the engine is capable of making. The way you ask that, makes me question you if there is a problem on the top end. At the "very" top you might have some falling off of the power (ever so slightly), but if you are getting a bog or sputtering, then your either too rich or too lean on the main.
