Carburetor Set MXT SPORT 17.5 mm complete with Choke compatible with Piaggio Gilera 50 cc 2-Stroke

The MXT-SPORT carburetor with a 17.5 mm nominal size is designed as a complete replacement and tuning carburetor for Piaggio and Gilera 50 cc two-stroke engines. Its near-standard dimensions support reliable mixture supply in everyday use. The pre-assembled electric choke enables stable cold starting without manual operation.

Product features:

• Carburetor in 17.5 mm version
• Completely supplied with electric choke
• Near-standard design for Piaggio and Gilera 2-stroke engines
• Pre-assembled main and slow jet
• Suitable as a replacement carburetor or for carburetor tuning

The design as a complete carburetor allows direct replacement in case of wear or defect. The near-standard dimensions maintain everyday usability of the mixture preparation, while the existing jetting provides a functional basis for further tuning work.

Technical details:

• Type: Slide carburetor
• Nominal size: 17.5 mm
• Choke: electric
• Jetting system: M6
• Factory main jet: 70
• Factory slow jet: 35

The technical configuration shows that the carburetor is designed for stable series operation. The installed standard jetting serves as a basis and can be adjusted depending on engine condition, mileage or modifications to ensure clean mixture preparation.

Vehicle and model compatibility:

• Piaggio 50 cc 2-stroke engines
• Gilera 50 cc 2-stroke engines
• Vehicles with standard 17.5 mm carburetor design

Since different intake manifolds, air filter boxes and peripheral components are used within the model series, checking the existing carburetor design is necessary to ensure compatibility.

Assembly and application notes:

• Assembly on near-standard intake manifolds possible
• Intended for use with original air filter boxes
• Electric choke is connected to the existing connection
• Control and fine-tuning of the jetting required after installation
• Adjustment of the main jet may be necessary in case of engine modifications

Correct jetting is crucial for smooth engine running, clean throttle response and thermal stability of the two-stroke engine, especially in continuous operation.

Note regarding checking before purchase:

• Please check before purchase whether the vehicle is equipped with an electric choke and whether the connection dimensions of intake manifold and air filter fit the 17.5 mm carburetor design.

Brief info: Carburetor - Installation, Setting & Tuning

Installation: Mount carburetor without tension, check intake manifold and gaskets for air leaks, adjust throttle cable smoothly, ensure fuel supply (gasoline, oil and vacuum).

Basic setting: Mixture screw usually open 1.5 - 2.5 turns, adjust idle screw for stable idling, always tune engine when warm.

Tuning:

• Main jet = full throttle / high load
• Needle position = partial load & acceleration
• Slow jet = idle & starting (usually does not need to be changed)

Check: Check spark plug image

• white = too lean
• black = too rich
• brown = optimal

Important: After changes to air filter, exhaust or cylinder, a new carburetor tuning is absolutely necessary.
