MXT Racing intake manifold 21 mm unrestricted open for Piaggio, Gilera, Vespa, Aprilia and Derbi 2-stroke scooters

The intake manifold connects the cylinder to the carburetor and guides the fuel-air mixture into the combustion chamber. This component from MXT is designed as unrestricted and replaces the restricted stock intake manifold installed from the factory. It fits 2-stroke scooters with Piaggio engines of the brands Piaggio, Gilera, Vespa, Aprilia and Derbi.

Product features:

• Unrestricted intake manifold as a replacement for the restricted stock intake manifold
• Flow inner diameter 21 mm - suitable for carburetors up to 21 mm bore
• Also fits carburetors in the 12-21 mm range
• Connection inner diameter 23 mm at the carburetor end
• Mounting distance 52 mm, mounting holes 6 mm - suitable for stock mounts in the cylinder
• Rubber construction with vulcanized metal bushings in the mounting holes
• Replacement recommended in case of cracks or porosity of the stock manifold - secondary air leads to uneven engine running, loss of power and in the worst case to piston seizure due to lean mixture

The unrestricted intake manifold increases the free cross-section in the intake duct and is particularly relevant when a larger carburetor than the stock carburetor is installed - the connection dimensions and the mounting distance determine the fit.

Mounting and application instructions:

• Remove the old intake manifold and clean the sealing surfaces on the cylinder. Screw the new intake manifold to the cylinder using the enclosed or existing mounting screws (M6, mounting distance 52 mm) and insert the carburetor. Check all seals and clamping connections for correct seating, as secondary air in the intake area leads to running instability and lean mixture.

Note on verification before purchase:

• Before purchase, compare the vehicle model, year of construction and the carburetor diameter of the used carburetor against the compatibility list and the connection dimensions (23 mm connection inner diameter, 52 mm mounting distance).
