jet mech Posted April 7, 2007 Report Share Posted April 7, 2007 I just installed a 2 into 1 w/ 33mm carb mods are Trinity Stage 4 pipes K&N no lid and new v force 3 reeds I installed the reeds at the same time as the 2 into 1. Jetting is 175 main 52 pilot air screw out 1.5 turns needle on the third clip (dek /eek no clue) and the left side is not running the same as the right almost running on one cylinder I saw that bigboy had a similar problem with his and sold it, are these things a joke or can they run your shee. I called Trinity for a starting point on the jetting and they say 170 main ( don't have) and a 50 pilot ( don't have ) and the way it is runing I really cant see a couple jet sizes making a difference if I just start to open the throttle it runs worse give it a little more and seems to run for a second but the left side smokes like a mother felt the exhaust gas on left side and it is cool (temp) give it more gas and right side will rev but left side blows even more smoke any suggestions i hate to give up on this but when my stock carbs ran great it is temping to just stick them back on I was just looking for a little more power and got what appears to be a big headache :shrug: Quote Link to comment Share on other sites More sharing options...
jlsparky7 Posted April 7, 2007 Report Share Posted April 7, 2007 What do your plugs look like? compression test? spark on both sides? try running it with the old carbs? tried switching the coils? Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted April 7, 2007 Report Share Posted April 7, 2007 Yes they do run good, mine runs awesome. You could have a intake leak, the reeds may not be sealing properly, etc..... Trinity pipes are not a real great midrange pipe. I would call cascade, but I am pretty sure they will tell you about what I recommended for jetting. Most of us run the 35mm pwk also. 185-190 main, dek needle, start in the middle, 50 pilot 1.5 turns out. I hope you sealed up the intake with new gaskets?

jet mech Posted April 7, 2007 Author Report Share Posted April 7, 2007 I checked the intake while running with alcohol and no difference in rpm I put in new gaskets new reeds, even went back to the old reeds to verify they were ok . I just put all my stock stuff back on and all is good runs great. So what the hell THe left side just loads up with fuel. I set the float its good Needle is on the 3rd pilot is now a fifty still loads up freaking wierd man. should I maybe try some liquid gasket shit to eleminate the possability of a leak or would that just f@#k it all up, this is truely frustrating. any more advice anyone besides leaving my stock set up on it one thing I will say is that this set up looks really damn good mounted I was just wish I could get it run run as good as it looks :: Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted April 8, 2007 Report Share Posted April 8, 2007 Make sure the needle orifice in the 33mm carb is ok. They dont have a brass sleeve, so when the slide needle wears it out, it will run really rich and has to be replaced. Use dry gaskets, maybe take the carb apart and clean it out real well. Its hard to say without inspecting the install, but nothing is really too hard when you put it on. Quote Link to comment Share on other sites More sharing options...
jet mech Posted April 8, 2007 Author Report Share Posted April 8, 2007 What do you mean by needle orifice the main jet or the part that holds the needle in the slide not quite sure what you mean I will go get a new needle this week you guys say the EEK or DEK is the best right Quote Link to comment Share on other sites More sharing options...
jet mech Posted April 8, 2007 Author Report Share Posted April 8, 2007 Just wanted to mention that when I bought this set up (used) it had a 35 pilot and a 158 main seemed a bit lean so set up per trinity's specs to start think i should put them back in an see I am on stock carbs with 300 mains and a 27.5 pilot and runs great is the carb size change that significant :shrug: Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted April 8, 2007 Report Share Posted April 8, 2007 (edited) keihin jet sizes are different from mikuni. It sounds like that carb was one of two carbs off a banshee. I wonder if there was something wrong with it, thats why he sold it used? The orifice where the needle slides down in when the throttle is closed. What needle is in it right now?

jet mech Posted April 8, 2007 Author Report Share Posted April 8, 2007 The needle is a dej and the thing was sold all together he said he had it on his sons shee I checked all the insides of the carb looks good also do you use the o-rings between the reeds and the billet intake or did you use gaskets i got mixed info from trinity one guy said use gaskets and the other said use the o-rings i put all new seals in the carb and the intake and if there was a leak between the carb and the engine wouldn't that cause it to run lean and also if it was one of two the jetting should remain the same right it still is only feeding one cylinder at a time or am i just way out there i do appreciate all of your help i am bound to get this f#@ker going it is something very simple i am sure Quote Link to comment Share on other sites More sharing options...
Banshee0028 Posted April 9, 2007 Report Share Posted April 9, 2007 I would first try a bigger main, esp since its a 33mm instead of a 35mm. My 35mm used 190 mains with similar mods, so you might need around 185-195 with your carb setup. If there are no other air leaks, and your comp is similar in each cyl, then not sure what else might be causing the problem? Oh, did you swap the coil wires around already?

jet mech Posted April 9, 2007 Author Report Share Posted April 9, 2007 I did not swap plug wires i figured since it runs perfect with stock carb set up all in that area is good to go thinking eek needle 45 pilot 185/190 and try it again keep the ideas coming though thanks guys oh and this bike is only 3 months old so Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted April 9, 2007 Report Share Posted April 9, 2007 I used the o-rings on the intake. The carb is constantly pulling fuel and air since both cylinders are using it, so it does not really feed one at a time per say. I would try the jetting at 185-190 main, dej needle is leaner than a eek, but slightly richer than a dek. Try calling cascade innovations and see if they have a setup jetting spec for that 33mm carb. They sell a lot of 2 into 1 kits and do quite a bit of tuning 503-663-2887. Ask for Chris. Check the plugs, maybe swap them. Make sure your not forgetting anything when your swapping out the 2 into 1 intake. Quote Link to comment Share on other sites More sharing options...
jet mech Posted April 9, 2007 Author Report Share Posted April 9, 2007 I will call cascade today thanks again Quote Link to comment Share on other sites More sharing options...
fox_forma Posted April 9, 2007 Report Share Posted April 9, 2007 I ran the 33 pwk 2into1 on my old shee which had FMF pipes, mild trail port and K&N with no lid. After losing my damn mind over that carb so many times I finally ended up with a 185 Main, 45 pilot and needle on 3rd clip (forget what needle is was though) And this was right around winter time with the temps in the 30's. That carb was such a bitch to jet for some reason. Also make sure it is straight up and down in the boot or it will cause one side to get more fuel then the other.

400rednEX Posted April 9, 2007 Report Share Posted April 9, 2007 (edited) are you using the stuffers that came with the reeds? i used the cascade open stuffers and they didn't sit flush with the cages. i had to file then hone them flat. the open stuffers won't work with the o rings either because the o ring goes into the intake cutout. i had to use gaskets. before i put in the v force 3's and the pod filter mine ran perfect with a 48 pilot, eek needle in the middle, and 178 main. with v forces and pod filter i had to drop the needle 1 clip. it runs good now but i'm going to try a couple different setting.
