The PZ25 conversion kit for manual carburetors includes an intake manifold, a fuel filter, and upgrade/repair parts for motorcycles, off-road vehicles, and go-karts.--DTEKGAZ

PZ25 Manual Carburetor: Precise manual control. Without an automatic choke, cold starts and operating condition adjustments are made manually via the choke and jet needle. This carburetor is suitable for experienced riders and racers. Fully adjustable design: Equipped with main and pilot jets, jet height adjustment, mixture screw, and idle adjustment, it allows for millimeter-precise fine-tuning to altitude, temperature, and engine modifications. High fuel flow: The 25mm jet meets the demands of high-revving 125-250cc engines and optimizes fuel atomization. Optimized intake manifold: Internal polishing and aerodynamic design reduce turbulence, improve intake efficiency, and optimize throttle response. Enhanced sealing: Thickened flanges and special gaskets ensure a perfect seal to the cylinder head and prevent power loss due to air leaks. Lightweight construction: The aluminum alloy used reduces weight while providing excellent heat and vibration resistance. Dual fuel filter: Its metal mesh and high-density filter paper effectively block rust, deposits, and other contaminants, protecting the carburetor jets. Transparent viewing window: Allows direct observation of fuel flow and purity, facilitating maintenance. Universal interface: Standard 6mm fuel inlet/outlet connections, compatible with most small engine fuel systems. 【Recommended Applications and Vehicles】 Compatible Engines: Optimized for 125-250cc single/twin engines, air- or liquid-cooled, especially suitable for high-revving racing preparation. Typical vehicles: Off-road motorcycles (e.g., some modified Honda CRF and Yamaha YZ models), karts/racing cars (as a replacement for the standard, rev-limited carburetor), quads/SSVs (sport models under 250 cc), vintage motorcycles (as a replacement for outdated carburetors).
