Two Stroke Engine Intake System
In the motorcycle two steps, the system does not use the gas intake valve, in its development there are a variety of
introduction of gas system are:
a. Reed valve system
b. Rotary valve system
c. Piston valve system
d. Crankshaft system valve
Reed Valve System
Motorcycle reed valve system is a motorcycle that opening and closing of the new gas inlet canal is governed by a device called a reed valve or valve also called harmonica. Reed valves are very sensitive to external influences. Reed vave or harmonica reed valve or valves are only used on two stroke engines. But not all two stroke engines using the harmonica valve. Harmonica valve to open or close the gas line from the carburetor to fuel the crank chamber. Reed valve mounted on the inlet motorcycle. Its location is after the carburetor when viewed from the direction of the new gas inside.

In this type motorcycle carburetor be installed on the side of the cylinder.
Example: Yamaha, Suzuki, and Kawasaki.
This valve can be set, depending on its needs. Error setting the harmonica valve can cause a gas leak.

| Figure 1. Reed valve |
Reed valve works by changing the pressure in the crank chamber. This occurs when the piston moves upward from BDC to TDC reed valve opens due to the vacuum in the crank chamber. New gas into the crank chamber. If the piston moves down from TDC to BDC reed valve closes. then the gas will get into cylinder.
Inspection and maintenance:
1. Examination of the reed valve should be done with caution because of the reed valve is very precise. Do not touch directly by hand and away from the salt. Reed valve must be stored in a dry and clean, and avoid sunlight.
2. Check the state of the license plate of possible defects, loose or cracked. If there is damage, correct. Measure the slit valve stopper. If the gap is too big of a standard then the stopper can be damaged. If the gap is too small then the ability stopper motorcycle going down.

Rotary Valve SystemSisitem
motorcycle with a motorcycle rotary valve is opening and closing the
gas inlet canal is governed by a new device called a rotary valve or
rotary valve . In motorcycle carburetor with this system is in the tub so that the crank is not visible from the outside . Example : Yamaha , Suzuki , and Kawasaki .Rotary valve is driven by the crankshaft . The opening and closing according to the processes that take place in the cylinder . If the piston moves from BDC to TDC rotary valve opens new gas inlet canal so that the new gas entry into the crank chamber . The gas will be supplied to the combustion chamber when the piston moves from TDC to BDC .Piston Valve SystemMotorcycle
piston valve system is a motorcycle that is opening and closing of the
new gas inlet canal and channel the exhaust gases regulated by the
piston or directly carried out by the piston . At this motorcycle carburetor mounted on the side of the cylinder . Example : Yamaha . The most simple system compared to other systems .Valve Crankshaft SystemMotorcycle crankshaft valve system is a motorcycle that opening and closing the gas inlet canal by a new set crankshaft . Motorcycle carburetor system is mounted next to the crank tub . Example : vespa .
