Optimized intake flow guidance for Yamaha RD350 two-stroke tuning projects!
This RD350 reed valve stuffer is designed to shape the intake passage around a compatible VForce reed valve assembly.
The insert is positioned in the intake area of the appropriate reed block and is intended to improve the geometry of the flow passage.
In performance two-stroke engines, the design of the intake tract is an important consideration. In addition to the carburetor, intake manifold and reed valve assembly, the geometry of the intake passage influences airflow behavior.
What Does a Reed Valve Stuffer Do?
A reed valve stuffer is a shaped insert fitted into the reed cage area. Its purpose is to guide the incoming air-fuel mixture through the reed valve assembly.
By modifying the internal passage geometry, the insert can help reduce unfavorable cavities and create smoother flow transitions.
The objective is to provide a more controlled flow path towards the engine.
Key Features
Flow-oriented design for the intake passage
Guided air-fuel mixture flow through the reed block
Designed to reduce unfavorable cavities in the intake tract
Compact shaped insert for the intended reed cage
Suitable for RD350 tuning projects with compatible reed valve assemblies
Applications and Compatibility
Designed for use with an appropriate VForce reed valve assembly in Yamaha RD350 applications.
Important: Different reed valve assemblies may be used in RD350 engine conversions. Please verify compatibility with your existing reed block before ordering.
Installation Notes
Check the fit against the existing reed valve assembly before installation.
Ensure correct positioning and sufficient clearance for the reed petals.
The insert must remain securely positioned without interfering with reed valve operation.
Modified reed cages may require additional fitting work.
