39 pwk or 34 pwk air stryker whats better for me?

[banshee mulisha]

Ok im gonna try to describe what i have the best i can. OK here it goes, 98 bored.020 over with a woods port from hi-tech horsepower(highly recommend),wiseco prolite pistons,cool head with 19cc domes, ngkbr8ev plugs,+5 timing,v-force 3 reeds, um aluminum open air box w/ k&n 250r filter,DMC 916 pipes and silencers,300ft above sea level and i run golden spectro 40:1. No problems with the pwk, but is the air stryker a better carb? If so what jets,needle shouuld i use if i go with the 34????

[Snopczynski]

they dont make a 34mm pwk. Did you mean 34mm PJ? I would run a pwk 35mm. Ditch the vforce setup also. Roll with stock cages on low tension carbon tech reeds.

[IrideA250R]

yea, there is no 34 PWK, 28,33, 35, 38mm on those. I disagree on the reed cages though, the VF3's do great.

 

If it is a 34mm PJ, it is very likely a stock 250R carb. They are not nearly as good of a carb as a PWK.

The vf3's on a ported 350 and a 4 mill 396cc made 2 hp less than a set of carbon tech mid reeds on stock cages. Thats with a set of ptr mids, pro circuits, and with single carb, and twin carbs. The vf3's are for drag motors, not trail, play, and mx motors.

thats great, with your setup. With other setups they've proven to be the best out there. Just because something was down a little power on your setup doesn't mean it will be on everyone elses. That's what is great about Banshees, so many choices. That being said, I doubt he notices much if any difference at all in switching reed cages, which is why I said don't bother swapping, run what you have.

[Snopczynski]

It wasn't just my setup, it was ran on 2 different motors with all sorts of different setups. They both have different port work also. The vf3 is a gimmick for anything less than a drag or top end only motor. I have verified the difference with my seat of the pants dyno also.

 

Here is the problem with some people on this board. They read a guys post and don't pay attention to what he is trying to do. They just tell him wether or not he should buy something he is already looking to ask about. If the guy has a woods port, a ton of compression, a ton of timing, and he is looking at a 2 into 1 intake, then why would he need a high flow reedcage setup with no reed stops? I look at what this guy listed, and say a low tension or low end power reed petal with a stock cage will help him achieve what he wants to do. Just because his reed cages cost $200, doesn't mean they will work the best on his setup compared to a $75 set of replacement petals for stock cages. I do dyno testing and swap parts out on my bike for a reason, thats cause I learn what works the best and use it.

Sorry for the confusion, its a 35mm pwk airstriker. So that said would this be a better carb than my 39mm pwk non airstriker??

[Snopczynski]

The 39mm is too big. If you know how to tune the power jet on the air stryker than it would be a good choce. Either way, you will lose velocity with too big of a carb and in turn lose power.

Snopczynski, You helped me nail the jetting on the 39 and you seem to know your stuff. So i'd like your advice on jets for this 35 and any other tips you have. Also im looking into the other reeds, i have a friend who wants these v-force 3's

[Snopczynski]

Low tension carbon techs are easy to find. If you want mid tension reeds I have to call Carbon Tech and make sure they kept the specs to cut them.

 

Main 195, eej needle, start in middle clip, 45 pilot jet, 1.5-2.0 turns out on the air screw.

well actually, he was asking which carb was right for him, not which reeds, but I digress.

 

to the original poster, if you're looking for a good single carb setup, go with the 35mm PWK and follow Snops jetting suggestions, they will get you in the ballpark and you'll be able to find tune it in from there.

Have you ever even ran both setups on a bike? Have you ever dyno tested the setups? I would guess by your resistance tha answer is gonna be no.

[IrideA250R]

run both, yes. My stock cages and aftermarket reeds are now in my parts bin along with all my other stock parts I don't need. Dyno test? Nope, I run my bikes in the real world for testing where results are proven. When I swapped to the VF3 reeds I noticed a bit better throttle response, and a bit more topend. Nothing world beating, but they are worth the money in my opinion.

 

Why are you so stubborn about understanding that what works great on YOUR setup might not work on someone elses setup? There is more than 1 way to skin a cat.

Wow i guess i started a pretty heated topic. Anyway, how about throttle valve size? I have a .5 and a .6 i think. I dont have them in front of me but know they are 5 and 6 just not sure of the . :ermm:

[IrideA250R]

you're right, I apologize. Regarding throttle valve size, do you mean the slide?
