The Keihin φ20 carburetor is the most popular for 4-stroke minis. It delivers the power and torque you expect from a big carburetor. Two types are available: a light carburetor kit that matches the intake port diameter of a stock cylinder head, and a big carburetor kit that matches the intake port diameter of a bore-up cylinder head.
 
○ Left-side exhaust type
○ Compatible with intake port diameters from φ22
○ M/J#85 P/J#35 already installed
