Malossi PHBG 19mm Round-Slide Carburetor - Yamaha / Piaggio

This Malossi 19mm carburetor kit gives compatible 50cc two-stroke scooters the airflow and fuel-delivery capacity to support a livelier performance build. Its PHBG 19 BS round-slide carburetor pairs a metal body with a black float bowl and accessible adjustment screws, while the included remote manual-choke hardware lets you position the starter control where it is easy to reach.

This product is intended for off-road use only. This product is not intended for use on public roads or land.

Key Features

• 19mm performance bore: Increases airflow capacity over smaller stock carburetors to support stronger RPM and power potential when properly tuned.
• PHBG 19 BS round-slide design: Provides adjustable fuel delivery for compatible two-stroke engine setups.
• Remote manual choke: Included Bowden cable and starter lever replace automatic-choke operation and allow chassis or handlebar placement.
• Malossi calibration: Factory calibration provides a starting point; final tuning is required for your engine, intake and exhaust combination.
• Italian engineering: Developed with Malossi endurance testing and made in Italy.
• Supporting hardware included: Choke-control components, fittings and mounting hardware accompany the carburetor.

Compatibility

This is a performance conversion that requires final tuning, not a promise of stock-carburetor interchangeability across every model year. Confirm engine version, intake mounting, air-filter connection, throttle-cable arrangement, and fuel-system connections before installation. Set the jetting and idle for your specific setup. For best results, pair it with a suitable larger intake manifold, performance reed valves, and a racing air filter.
