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

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

Yes the slide

I haven't seen a lot of people adjust slide cutouts (thats whats different between the 2, the cutout on the bottom of the slide).

Yea i researched it a little,at $75 each i wont worry about it. Just making sure it wasnt critical.

Like I said its been verified on 2 entirely different motors with different configurations and different port work. I am talking about carbon tech reeds, not just aftermarket reeds. There is a difference, because you can get low, mid, or high tension reeds and that will effect where they work in the powerband. Like I also said, my setup has been confirmed with riding the bike and running it on a crank dyno. I understand all the variables you speak of, but I would not say something if I had not confirmed it and felt that it was a null and void point. I am not stupid, and obviously I know each banshee can be different. There are general things that always can remain a constant, and this is one of them. If you have a high tension reed with no rev plate that is supposed to move a ton of air like the vf3. Then its going to be a top end oriented reed setup like it is. If it is a low tension or middle range tension reed petal with a rev plate to limit opening and end flutter then its going to be a reed petal setup meant for bottom-midrange oriented power. The slits cut in the petal also limit the amount of opening and tension it takes to open them. Next time we have a lowend or midrange motor on the dyno do you want me to swap the reeds and cages again just to make that 3 tested motors with results pointing in the direction of the carbon techs again? I think at the magical number of 3 it becomes more than likely and more than just a coincidence that they made more power. We are not just looking at hp numbers here either. The torque is always more, and the tq and hp curve is also always bigger in the sense that it provided more acceleration and power lower down in the rpm range than the vf3's did.

 

I dont know what slide cutouts we dyno tested, but if there is a standard cutout that most get shipped with, I would bet it was that slide. Also, is there different slides because of the air strikers? Like to say a .5 is in the pwk, and the 1.0 would be in an air striker? I know the air striker is supposed to be an mx carb for dirtbikes mainly. So slide cutout probably effects throttle response if I had to make an educated guess. All the pwk's we have and order they dont specify a cutout on them though.
