Boyesen: engineering for intake systems and engines

The history of Boyesen goes back to 1972 and Eyvind Boyesen’s work on reed induction. Its dual-stage technology is one of the developments described in the brand’s official history. Since those early components, its catalog has expanded to include intake solutions, covers and other parts for engines used across different disciplines.

At Motarea, these families are organized to help you find both complete assemblies and the components needed to maintain them. Each shortcut shows Boyesen products; before choosing, check the application and the system on which the part will be installed.

Reeds, reed cages and intake components

The reeds and reed cages include Rad Valve assemblies and replacement parts from different ranges, including Power Reeds, Pro Series and Superstock. A complete cage and a set of reeds have different contents. Check the receiving cage type, material and specified part number to select the appropriate solution.

The intake diffusers and manifolds group together components that work at different points along the inlet tract. This family includes diffusers and connecting boots. Compare the shape, mounting diameter and included fasteners; sharing a manufacturer does not make two components interchangeable.

Covers, cooling and carburetion

The covers and Supercooler kits shortcut brings together Factory Racing covers and Supercooler cooling assemblies. Distinguish between a clutch cover, an ignition cover and a water pump kit: their function, contents and installation differ. The page for each part number lets you check which parts are included and which existing components must be retained.

The carburetion components include solutions such as QuickShot and carburetor float bowls. Before selecting a cover or assembly for the accelerator pump, check the carburetor type, connections and intended adjustment. Follow the manufacturer’s instructions for installation and tuning.

Gaskets for engine maintenance

The engine gaskets help you find sealing components for clutch, ignition and cooling covers. Check the shape, mounting holes and corresponding application. A gasket must match the specific cover and housing; a similar appearance is not enough.

For any work, always consult the product page: compatibility, contents, specifications and installation conditions must match the installed assembly. This helps you distinguish replacement parts from kits and prepare maintenance using the specific information for each part number.

Water pumps and cooling system spare parts

The Supercooler family is complemented by Boyesen water pump components and spare parts. Distinguish the cover, impeller and other pump components from a complete assembly: check the contents and application for the specific part number. This link lets you find cooling parts without confusing them with an ignition or clutch cover.

To prepare for the work, identify the installed assembly and consult its instructions. Sealing elements, components to retain and assembly torques depend on the application; sharing the Supercooler name does not make all its parts interchangeable.
