THE WHY AND HOW OF THE MOSSBARGER REED CAGE

Why should I use the MOSSBARGER 8-PETAL REED CAGE? How will it improve my engine? These are viable questions that need to be answered with facts and not just false advertising copy. First, the MOSSBARGER 8-PETALL REED will improve the engine power throughout the entire RPM range, because it flows more air at any given RPM than the stock or any of the other after market reeds. This means better low-end power out of turns, and more mid and top-end speed for the straightaway. Secondly, the MOSSBARGER REED will make the engine easier to start, idle smoother, and in general will make the engine easier to tune. This is due to the higher air velocity (speed) and added airflow provided by the design of the reed cage.

Now to the "HOW" of the MOSSBARGER REED CAGE, and why it works. There are three basic reasons for the horsepower gains of the MOSSBARGER REED.

1.) The cage design is very important, the MOSSBARGER "POWER GROOVES" channel the air through the cage faster and with less drag, thus reducing flow robbing restrictions of conventional cages. Also, the "ROTO-FINISH" on the cage surfaces improves flow over other surface finishes.

2.) The reed petal design and petal material is a very big part in how well the unit works, and is so often an overlooked factor. The MOSSBARGER PETAL DESIGN is a long, narrow style petal that is flexible and light in weight, for instant petal response and for more flow area. The MOSSBARGER REED MATERIAL has steadily been improved since it was first introduced in the late sixties. It is the best known material for fast response, horsepower, and long petal life. This material is always trying to be copied, from original equipment manufacturers, to other after market companies.

3.) Reed stops are a must for any reed valve to work properly. The reed stop controls the petal opening and closing time for efficient operation. The stop keeps the petal from opening to far and taking to much time to close, thus hurting air flow, and power. The reed stop is similar to a valve spring in a 4-cycle engine, it closes the valve on the seat. The MOSSBARGER REED STOP is a solid design to help increase the crankcase pressure for more power.

AIR FLOW COMPARISONS OF REED CAGES

All test were performed at 10" of water pressure, which best simulates atmospheric conditions.

MOSSBARGER 8-PETAL REED 71.40 CFM

STOCK SUZUKI 1988 LT250 59.60 CFM

STOCK HONDA TRX 250R 54.60 CFM

FMF REED CAGE 53.62 CFM

The MOSSBARGER 8-PETAL REED CAGE out flows and produces more power than any other reeds, cages, or any modified stock cages. This is no surprise; it was designed to from the start! Certainly the old saying of "NO FLOW MEANS NO GO" is very true when applied to reed cage technology. 
 NOTE: CFM. STANDS FOR CUBIC FEET PER MINUTE OF AIR

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.
