MXT Intake Manifold RACING 21 mm unrestricted for Minarelli vertical / Yamaha BWS / MBK Booster

This intake manifold from MXT is designed without restriction and replaces the standard restricted intake manifold on vehicles with a vertical Minarelli engine. For vehicles where a larger carburetor is to be installed, replacing the intake manifold is mandatory.

Product Features:

• Intake manifold without restriction - direct replacement for the standard restricted intake manifold
• Opening size 21 mm - suitable for carburetors with the corresponding connection size
• Rectangular 4-hole flange at the cylinder head connection
• When installing a larger carburetor, replacing the intake manifold is mandatory

Technical Details:

• Product category: Intake manifold
• Engine type: Minarelli vertical (air-cooled, 2-stroke)
• Version: Racing, unrestricted
• Opening size: 21 mm
• Fastening: Cylinder head flange 4-hole

Vehicle and Model Compatibility:

• The intake manifold fits vehicles with a vertical Minarelli two-stroke engine, including all variants of the MBK Booster and MBK Stunt, all Yamaha BWS and Yamaha Slider variants, Yamaha Spy, Yamaha Zuma (vertical engine), Aprilia Amico, as well as models from Italjet (Pista, Scoop, Yankee) and Adly (PT50, Rapido). The requirement is the vertical Minarelli engine.

Installation and Application Notes:

• The intake manifold is replaced directly with the stock intake manifold, and the 4-hole flange is attached to the cylinder head. Check all gaskets for correct seating during installation; if the carburetor is changed simultaneously, coordinate the connection dimensions of both components.
