Affordable intake manifold for 26–30 mm PWK carburetors, designed for 50 cc motorcycles with Derbi or AM6 engines.

The round passage to the reed valve measures 32 mm. For carburetors smaller than 26 mm, we recommend the MF15.18901 intake manifold.

Made from durable, vulcanized rubber, the MotoForce Racing manifold resists hydrocarbons and provides a secure seal for the intake tract. Four elongated mounting holes allow fitment to Minarelli AM6 and Derbi engines. A reinforced rear section helps support the weight of a PWK carburetor.

Compatible with carburetors with 35 mm or 36 mm connections :

• Keihin PWK 19–30 mm — 35 mm connection
• Dellorto VHST 24–28 mm — 36 mm connection
• Dellorto VHSH 30 mm — 36 mm connection
• Dellorto PHBH 26–30 mm — 35 mm connection

Connection sizes are measured on the carburetor. The rubber manifold may have a slightly smaller opening, as it expands during installation.

This manifold can also be used with 32/34 mm PWK carburetors that have a 40 mm connection. To fit one, place the manifold in boiling water for a few minutes, then install the carburetor directly onto it. As the rubber cools, it will adapt to the connection.
