The proper racing reed cage should have as much air flow as possible, because more air flow means more go!!! Reed cages should have long narrow easy opening petals and high air speed. Reed cages should not have inserts, boosters or stuffers as they cut the air speed and kill the total air flow. Reed cages should not have wings, bars or airfoils inside the cage itself. This makes the airflow travel a longer distance that slows the speed, and they cause a severe restriction to the movement of air. The only function of the reed cage is to deliver the largest amount of air at the highest speed possible. Always remember that!! Do not believe the big fancy ads that say airflow isn't important, remember MORE FLOW = MORE GO!

MOSSBARGER POWER GROOVE REED ASSEMBLIES

With all racing engines, the more air you can flow into the cylinder at a high velocity, the more power can be obtained. Below are measurements of different reed valve assemblies measured at 10" of pressure drop, with all figures corrected for temperature and humidity. Note that CFM is cubic feet of air per minute.

80cc engines 26/28mm carburetors
125cc engines 34/35mm carburetors
250cc engines 35/36mm carburetors
500cc engines 36/38mm carburetors

These are estimated Flow Rates of a popular carburetor.
