Using something similar in my 1999 2-stroke Polaris xc700 snowmobile with 39mm Keihin PWK carbs. They increase the mixture velocity and atomization at lower throttle openings, and does a good job at cleaning up the throttle response in low/midrange

that looks like a big joke i have seen more junk people come out with to stuff in carbs to increase power .dah if you put anything in a carb bore it takes away flow not add hp

I've got the Boyesen magnesium clutch cover
on my hot rod XR50 (thats 88cc's now) and
it made a huge improvement in power gains!!

I does look cool though.

No idea. I googled it to try and find some info but no proof that it works. Remember the "Tornado" that you put in your cars intake? Worthless. I bet the "powerwing" is the same.

Yeh, if you bought all the mileage / power improvers they sell, you could run on water and get with 3.1 milliion horsepower while getting 11.87 light years to the pint, US pint not IMP with 0 to 100 runs under .02 seconds without really getting it on.

in single cyl. two stroke engine, and it seemed to help with a little "glug or slight bog" off idle, but did nothing else, as far as we could tell, this was in a well worn 125nx, I doubt it would do a thing for the Bonnie, However a well placed lump in the intake port in the head to increase the velocity of the intake charge will help but you have to have a flow bench, and a tig to get it right.

I can't see any noticeable gains on the Bonnie (especially when using the stock CV carbs) other than the slightly increased response from a lighter wallet
