Would this even do anything??

i do not plan to buy one.... but would this even give u any improvement???

i assume the point is to direct the airflow straighter.....

I can only say it will add turbulence, there is no such thing as straightening air, any thing placed in an air stream will produce eddy currents which disrupt air flow.

Topic for discussion, here is how I see it please feel free to try to convince me otherwise.

INCREASES horsepower and torque in 2-stroke and 4-stroke engines.
I should love to see the Dyno results.
AERODYNAMIC design maximizes velocity generation and power gain
Adds unwanted eddy currents, disturbs air flow.
WING CHANNEL minimizes disturbance at needle jet without affecting jetting curve
Adds 8 extra surfaces resulting in excessive turbulence at needle jet.
PRECISION fit doesn’t reduce size of carburetor bore so there is no loss of power
Adding anything to and inlet of a carburettor will impede air flow.

I have a pro design billet intake that uses similar technology. I have never used it though. It will be going on Money Pit's bike. I will post results.

ok thats what i figured..... pointless crap with keywords that make it sell good

and straitening the airflow was the only thing i could come up with...... and yeah ur theory makes sense that it makes it worse.

my blaster pro-design lacks that ?

ken tried one fashioned after the "power now" brand that uses just the horizontal wing, said he didn't notice any difference at all, and pulled it upon next carb cleaning.
their theory is it directs the air under a partially opened slide for more velocity over the jets ?

Exactly what the slide cutaway is designed to do, stuffing with air directly before the slide nullifies the cutaway.

There was a time that folks thought that placing a screen of metal fly gauze in the inlet would help atomisation, but the only thing it did was to add a 10% restriction.

I have and run the same exact one. I never even tried running it that way. I cut it all out and matched it to my vf3's. Has been working great.

I just recently got a Boyesen rad valve and on the inside it looks similar. The splitting of the 4 channels I will call them, says that with the Yamaha blaster set up being as the air/fuel mix from the carb and such at the severity of the angle (carb to reeds) the "4 channel air ducts" directs the flow more evenly throughout the reeds , hence restricting the turbulence to reeds and evening the flow through the reed cage. I can see the meaning behind this but as a strait shot I would see no reason for it to work.. Like I said though the Rad valve is a "similar" set up but with more angles and it being thinner at entry and opens up wider right before it hits the reeds..

Now me being me I had to experiment a little. Since I cannot see the flow of air I figured the next best and closest thing I can see flow is good ole H2O.. I hadn't thought I would see much difference between the Rad valve with being split into 4 channels and a just 1 channel making the same turn.. But to my surprise without the 4 separate channels everything was directed to the outer (right side) reeds and very little to the inner 2 (left side).. With the same test with the Rad valve the distribution was much more even throughout the 4 channels/reeds.. By no means am I saying this improves anything. I am only stating what I have noticed.. If it helps I don't know..
