sheefreak Posted July 16, 2009 Report Posted July 16, 2009 I run a 55 pilot on a 10 mil cub. I ran a 52 on my stock cylinder setup but had the airscrews close down to 3/4 turn. Coulda used a 55 on those as well. Quote
tundish2800 Posted July 16, 2009 Report Posted July 16, 2009 (edited) im running a stock cylinder four mil with a 120 dump and a 118 main with a 52 pilot i run the air screw out 1.5 turns. I have 34pjs and it seems like it is close on the jetting Edited July 16, 2009 by tundish2800 Quote
dajogejr Posted July 16, 2009 Report Posted July 16, 2009 There ya go... PJs jet a hair different than PWKs, but...I'd say you're damn close to what this guy needs as well. Quote
tundish2800 Posted July 16, 2009 Report Posted July 16, 2009 i only use the stock bowls but i dont race over 300ft Quote
BigRed350x Posted July 16, 2009 Report Posted July 16, 2009 There is also a jetting difference between the air stryker series carbs and normal PWK's as well as with the PJ's. I've got a set of PWK's that run a 55 pilot and a set of Air Strykers that run a 48 pilot on the same setup. I've also got a set of PJ's that have some 70's in them. LOL Quote
AWR Posted July 16, 2009 Report Posted July 16, 2009 my 34pj's ran a 55 pilot with a .118 main and dump tube with the power jet closed.on cold night's i would crack the powerjets just a hair. Quote
gregrob Posted July 16, 2009 Report Posted July 16, 2009 Funny Jeff at FAST had the 70's in those PJ's on my drag bike and I dont remember having to spend half the day cleaning it out. Also funny that I have 68's on it right now and it idles fine and I dont have to clean it out even with a huge main for this elevation and the needle as rich as it will go. In fact you can dump the clutch andpin it right off idle and it will pull through it and light Kevin also uses pilots in the 62-65 range. He was helping me on the setup for these carbs and thats whathe told me to run. 68 was the closest I had. Quote
dajogejr Posted July 16, 2009 Report Posted July 16, 2009 A. I'm pretty sure I have more experience tuning methanol than you. B. I'm pretty sure settings that work at sea level are not going to work at your elevation and get max or even close to max performance. You can run methanol as fat as you want, you can almost drown the motor in it before it sputters and bogs... You'll learn that's still a far cry from having an optimum tuned motor. Funny...weren't you guys bashing the living shit out of Jeff saying the bike was a turd you bought with his tune, and now you 180 and say the bike is fine and you didn't have to tune it much. If Jeff had 70s in there, you didn't have to spend all day cleaning it out...but you put 68s in there and then enriched the needle all the way...hmm.... Why? Hmmm.... Once again...your credibility is in question....go figure. Quote

Once again...your credibility is in question....go figure. I know what you mean on it will burn. Our modified dirt car runs meth and you can richen it to the point it produces 3 foot flames out the exaust at idle but never spudder on top. But thats not where it produces peak power. I tune the carb for our car but just didn't know where to begin on converting. What do you reccomend? You seem to have alot of knowledge. thanks to all whom have put in imput Quote
dajogejr Posted July 16, 2009 Report Posted July 16, 2009 I'd be starting with a .122 dump tube and .118 to .120 main. Gut your gas cap, drill the vent tube out to .125 Get a Pingle dual feed fuel valve, and as said...for runs longer than 300 feet, larger bowls are not a bad idea. 55 pilots. If you're in warm temps...50 or 52 should be fine. Quote

Once again...your credibility is in question....go figure. A. Im pretty sure you do too. Good for you B. The PJ's that USED to be on my drag bike were set up by Jeff for sea level, or as close to sl as Kansas is... Kevin Herr is also at sea level so his advice is based on that as well, not where I am. C. I know good and well how rich you can run meth and it wil still run, and I also know the difference when it cleans up and you get close on the jetting from the ground up, pilots, needles, and mains. I've experienced it on my duner where you can actually use the bottom and mid range unlike a drag port and having it well tuned is a beautiful thing. D. I absolutely never one time bashed Jeff's work or tuning on my drag bike. Nor have I ever said "it ran like a turd". Never, period. I have always Jeff did an awesome job porting building that motor, as well as I've said it runs amazingly hard up here and it's cool to think it still has a lot in it because it's set up for sea level. E. The carbs with 68's and needles all the way rich are a COMPLETELY DIFFERENT SET OF PJ'S that I set up. Far from being optimized at this point, but it will run without being cleaned out. F. If you're going to question my credibility get your facts straight. Show me where I said the things you claim I did. I would question your credibility as what you've posted here is 100% ficticious No disrespect intended daj. I just wanted to set the record straight. A lot of the supposed FAST bashing is propogated by a few of you guys more than it is reality. I've said more than once Jeff did a great job on this motor and treated me well when I did business with him. His nutswingers on the other hand I have no respect for. Quote
dajogejr Posted July 16, 2009 Report Posted July 16, 2009 I hope your dick is longer than your memory. And I quote: "Here's the deal, Jeff is a good guy and builds some good stuff. He also sells a lot of little "tricks" that you can do without but hey if someone wants to fatten his wallet with the stuff then more power to him!!!" As a business owner, how else would you take that? You think that's a compliment. I only read the first page...don't need to go any further. http://www.bansheehq.com/forums/index.php?...l=FAST&st=0 So....how's that credibility treatin' you right about now? And...the icing on the cake: http://www.bansheehq.com/forums/index.php?...884&hl=FAST A MONTH AGO, you're asking how to set yours up. Now you're a pro on setting up others? Quote
gregrob Posted July 17, 2009 Report Posted July 17, 2009 Weak. Just like I thought, you still cant show me where I said it ran like a turd or where I bashed Jefffs work or tuning. My credibility's treatin me fine, how's yours? Quote
