If you have a high-performance CNS carburetor on your gas powered motor bicycle then this intake manifold is a must have to get peak performance. This manifold is designed to match the intake port of your motorized bikes cylinder and provide a smooth flow of air and minimize turbulence which helps the engine run more smoothly. Not only will this manifold help boost performance, but it also provides a more solid seal which prevents air leaks that can cause poor idle and bog.

The BBR Tuning Large CNS High Perform Carburetor Intake Manifold improves efficiency and provides a perfectly snug fit for motorized bicycle engine setups because of its large design. Fits on most 48/66/80cc bicycle engine kits, it is designed for greater gas flow efficiency as well as a nice airtight fit that helps prevent any vacuum leaks that normally cause poor idle quality and bogging. This intake manifold replaces the white manifold sleeves in all CNS High-Performance Carburetors.

This is a 30mm intake manifold.
