What carb should I put on my KX500?

Looking at Roostius's flow bench numbers and info gathered from Kawasaki Team Green Mechanics we have come up with the following..

96-97 KX250 or a 2000 Cr250 carb.
Or you can go to Sudco and get a Keihin Quad vent Air striker 38mm for about 200.

You can use the newer Airstrikers as well but you need to block off a few things.

It will add 1 hp to the rear wheel on a completely stock KX500.. That is dyno confirmed.

The flow bench shows that it does just as well as a 41mm Airstriker for volume and velocity.   That is also dyno confirmed...

We need to come up with some decent jetting specs.

Sean Colliers bike.
pilot 55
main 175
16009-1613 NEEDLE-JET N89D - 2nd position
Slide 7

We ran this at Glen Helen 1700-1800 ft.. 50% C12 and 50% 91 California pump gas.

You will need the correct throttle and cable for which carb you choose.

shows you bigger is not allways better.
