360° Adjustable Manifold Inner diameter of the rubber sleeve 33mm, centre distance 45mm. The BS0272 is a 360-degree adjustable intake manifold, an aftermarket component designed to replace the stock manifold between a carburetor and an engine's intake port. Its key feature is a swiveling design that allows the carburetor to be rotated to any angle within a full circle, providing critical flexibility for custom motorcycle or small engine builds where space is constrained or a specific carburetor orientation is required for optimal performance and fitment. This adjustability ensures that the fuel-air mixture is delivered efficiently while solving clearance issues with the frame, fuel tank, or other components, making it an essential part for custom projects and performance tuning.
