POWER REED INTAKE SYSTEM
Power reed intake design is used to broaden the usable power band of 2-stroke
engines. At low engine RPM the piston skirt controls the fuel mixture intake as
on conventional 2-stroke engines. At high engine RPM a flexible reed valve
senses the increased need for fuel mixture and opens automatically, acting as
second stage "boost". This automatic sensing significantly increases
the usable part of the engine's power band.
CASE REED INTAKE SYSTEM
The case reed intake system improves the power of 2-stroke engines at low and
midrange engine speeds. The reed valve is mounted in the crankcase instead of
the cylinder which allows a wider intake area and creates more cylinder wall
surface area to support the piston skirt and ring(s). There is also room in the
cylinder for more transfer ports. Case reed systems also help dissipate heat
more evenly through the cylinder and provide smoother intake through the
cylinder.
PISTON REED INTAKE SYSTEM
The piston reed system inducts fuel directly into the cylinder through a reed
valve system similar to the Power Reed system. When combined with long stroke
engine design and large Power Chamber exhaust system, this intake system helps
the engine develop extremely good low to midrange power. This makes tractable
power and enhances rear wheel traction control.
