Description
Naraku Jet Flow CNC Intake Adapter for GY6
CNC-machined aluminum intake spacer from NARAKU. The NARAKU Jet Flow was designed to optimize airflow on 51 mm NARAKU cylinder heads. The spacer's tapered bore allows unrestricted flow from a 24 mm intake manifold into the 21 mm intake port of the 51 mm cylinder head (included in 51 mm and 52.4 mm NARAKU cylinder kits). The Venturi effect accelerates the fresh charge, improving cylinder filling. Result: increased torque!
With appropriate modifications to the original cylinder head or intake manifold, the spacer can also be used with a stock setup or tuning configurations below 90cc. The use of a 24 mm carburetor is ideal but not mandatory.
When installing, ensure a smooth transition between the spacer and the cylinder head. The spacer can accidentally be installed rotated by 180°. In this case, it will partially obstruct the intake port.

What is a reed valve spacer?
The reed valve spacer is an aluminum component that is placed between the crankcase and the reed valve. It is often used on 50cc 2-stroke scooter and motorcycle engines.
what is the function of a reed valve spacer?
Adding a spacer under the reed valve increases the height of the block, thus increasing the volume available in the engine block. In addition, the spacer causes the boost ports of the cylinder to be flowed freely, which can improve gas flow and performance.
It is important that the thickness of the spacer matches your engine setup. As a rule of thumb, the larger the displacement, the thicker the spacer. Since every engine is unique, you'll have to experiment a bit to find the right thickness.
Note: When installing a reed valve spacer, it is critical that the engine is properly sealed, so it is best to use new intake gaskets or engine sealant.
