locogato11283 Posted October 14, 2004 Report Share Posted October 14, 2004 my experience: i read on this site for months and talked to lots of people before i decided who was going to port my cylinders. i called and talked to jim. he was real easy to talk to. (and not one to ever blow you off) anyway i got the +4 12 port. i didn't have enough cash to get some bigger carbs right then so on went the stockers. you couldn't wipe the smile off my face or anyone who rode it for that matter. the bottom and mid is what really set this motor apart from the others. i've rode lots of ported banshees with peaky powerbands no power/all power shit happening. this motor pulls smooth and hard from the bottom to the top. the bottom is incredible for the power it makes up top. anyway, i bought some 35mm pwk's and i'm still fucking with them. i've tried lots of different jets. the only time this motor would bog like loco's is if i ran between a 45-48 pilot. i made one run with a 42 and pulled it right back in the shop.( it didn't seem to bog, i was on flat land though but it sounded like a vacuum) pay attention to tone while jetting. the only reason i was trying those lean pilots was because i have a slight rich condition just off idle like a 1/16th to 1/8th maybe into the throttle with these carbs. it's fine otherwise only sucks when i'm putzin'. i know for a fact my problems are only jetting issues not jim's port work. if i ever build another motor it will go straight to jim. his porting is top notch. if you want your motor to pull hard the whole way he's the man. feel the passion i tried a set of stock carbs with the same reaction. i mean it was identical to the 35mm pwks. i tried pilots all the way from a 42 to a 52. ran the same all the way thru.

prichard9966 Posted October 14, 2004 Report Share Posted October 14, 2004 heh loco, i think you should have thrown like a 60 in it even if it was rich at idle and seen how the midrange was. i can't imagine why you'd have such a dead spot unless you were lean. i hope you have better luck this time!

Justintoxicated Posted October 14, 2004 Report Share Posted October 14, 2004 (edited) I have had more problem jetting my passion 12-port (non-stroker) than anyone on the forum even you...It's been a whole year now! However after I ditched the stock carbs got V-force reeds and 33mm PWK's It is running MUCH better. My Carbs do NOT have the stock needles in them. I still do not have it dialed in all the way But I am getting closer. It's is runnign to the point where I can cruze right before the power band and slam the throttle at any minute to jump right into it. The powerband comes on hard, but it is not -light switch like. I have NOT dynoed my bike either. I have been learning about some differences in Jim's work that other builders would critize though. Some things make sense to me, but I do not do porting and unless I had numerous cylinders to play with I will never ever find out. Fattys are a good midrange pipe, maybe thats why I don't notice a dead spot? Anyways, it will take me some more time to tell for sure if I have a flat spot, but I'm starting to like my porting much more now. also you said pilots and different needles do not make a difference...I would have said the same thing about mains when I had my stock carbs. No matter what I put in it had shitty top end, I want from 340-380 and exact same thing happened every time (even though the plugs looked different) there was Lead from the fuel (or so I am told) fowling all over the plugs. And Yes I tried different types of gas. I have recently been runing MC1 50 to 1. Edited October 14, 2004 by Justintoxicated Quote Link to comment Share on other sites More sharing options...
reded Posted October 14, 2004 Report Share Posted October 14, 2004 All I know is I've been running stock carbs and mine runs fine. My brother and loco have 35's and theirs don't run fine. Only thing is, mine doesn't pull as hard as theirs on top. So I have bit the bullet and ordered a set of 35 PWK's along with a bottle of Ritalin, to keep me calm throughout the jetting process, and a bottle of extra strength Tylenol, so I don't feel the pain when I start banging my head off the wall.

BigRed350x Posted October 14, 2004 Report Share Posted October 14, 2004 I bought my banshee as a pile of parts from some kid that had no clue. I don't know where he had it ported, but its a great port job. Looks like it might be a home-made or somethin. Its awesome. I can run with any of the passion guys around here. I didn't have to change the jetting very much when I finially got the bike put back together. Moved the needle clip down one, and went up on the mains a few and it runs like a mad man. Lots of fun. Good luck to all you guys that are getting that dead spot. That sucks. Jump on E-Bay and get a new set of jugs and start over. Quote Link to comment Share on other sites More sharing options...
ssbanshee Posted October 14, 2004 Report Share Posted October 14, 2004 i did notice that some of the guys that have theres running right are running v-force reeds and 17cc domes anybody got theres running right that has a diffrent setup Quote Link to comment Share on other sites More sharing options...
rebelbanshee2 Posted October 14, 2004 Report Share Posted October 14, 2004 i did notice that some of the guys that have theres running right are running v-force reeds and 17cc domes anybody got theres running right that has a diffrent setup im running stock ported cages, and 20cc domes and it runs great. this winter is Vforce and 34pj time though Quote Link to comment Share on other sites More sharing options...
Proquad101 Posted October 14, 2004 Report Share Posted October 14, 2004 i did notice that some of the guys that have theres running right are running v-force reeds and 17cc domes anybody got theres running right that has a diffrent setup That's my set-up and it runs great. I dont have a boost bottle or a cross over tube, when I took those out I got better throttle responce when I am about 1/2 throttle all the way to top.

23champ Posted October 14, 2004 Report Share Posted October 14, 2004 Loco, sorry I wasn't around to back you up. (I just now found this post) Lets just say that I feel locos pain. After reading blue deuce's post in the product reviews forum last spring about his new Passion 12 port 4mm motor I couldn't wait to have mine done. I had been thinking of getting a set of cheetahs but the 3grad kinda turned me off . When I stumbled across BD's post, I think I fell in love with his motor more than he did. So I called my brother and one of my friends, who both wanted to do something differnt with their motors as well. I told them about this magnificent motor that I had just read about. They were both 100% totaly for it. We boxed up our cylinders and sent them away to jim. We all three talked to jim on a regular basis about the porting, we wanted our engines to be exact replicas of BD's. Jim agreed that he would go through all the motors at the same time,setting it up like "an assembly line". That way everyones motor would run identical and no one would be pissed because they were getting beat by the other. When our cylinders came back w/4mm cranks It was better than christmas. We all worked nonstop getting them back together. My freind "Jake" was the first to get his together, because I was waiting on my head to get shipped. He went through the break in and all that. After taking it easy for about 3hrs he said he nailed for the first time and thought "I was expecting more". Not only did it have a huge dead spot in the mid but, with 15 40 gearing it wouldn't even get on the pipe in 6th...Major disappointment. So after about 3 days worth of jetting and rejetting with almost no performance gains. we came to the assumption (sp) that we sould all go with bigger carbs (when I got mine together it ran just like his). So we drop another $500 in a set of PWK 35's, intakes, and all that. Yes, it runs better with the bigger carbs but, the power curve hasn't changed... Still a huge dead spot in the mid. I have tried every combination from 45-50 pilots, needle- everywere but up my ass, mains from 140-170 ,and no correction to the problem YET! But, unlike Loco I have not given up hope.. due to the fact that I don't have as much money as him, And that alone is the only reason why I gotta stick with this bitch. I got over 2grad in the motor and haven't been impressed with the overall performance yet. My latest purchase is a set of new throttle valves that have not come in yet but, when they do I'll inform every one the out come..good or bad Sould have just stuck with my original idea about the 421 cheetah. Probably would have been cheaper in the long run. Quote Link to comment Share on other sites More sharing options...

kenr74 Posted October 15, 2004 Report Share Posted October 15, 2004 Well, I decided to wait for more reviews before I dropped that kind of money. Personally I think that Passion porting and Rocket pipes are very overrated. Show me some dynos and then they can justify some of the hype. I guess I'm just lucky that I waited and ended up going with a local builder that I know does good work. Put on some Shearer pipes after I saw how they dyno'd against CPI's. My bike is much faster than I expected and it was a hell of a lot cheaper. Quote Link to comment Share on other sites More sharing options...
NYUK Posted October 15, 2004 Report Share Posted October 15, 2004 brutal...standing 8 count....1....2.... where is this guy ? in the begining i would see him posting and such.and i wondered how he has so much time to be on hq.got a batch of bad motors here and no one answering for them. a while back we had a guy did the same thing.built some gems and a couple of lemons.anyone around for the last 4 years remembers who i m talking about.he is out of buisness now because of posts like this.if i was jim i would step up and rectify the situation.or go the way of all pro.
