Dell'ORTO PHBL 25BS REG.2731 racing carburetor modification part, 25mm bore, suitable for two-stroke motorcycle racing engines.--DTEKGAZ

This high-performance carburetor is manufactured to the original racing specifications of DELL'ORTO (Italy), model PHBL 25BS, homologated according to REG.2731. As the racing version of the PHBL series, it is specifically designed for small and medium-sized two-stroke engines that require optimal responsiveness and maximum power at high RPMs. This product offers an equivalent or even superior alternative to original parts for race cars or tuned vehicles using this model. Furthermore, it provides a first-class basis for fuel metering in the most demanding engine tuning projects. Its strengths lie in the faithful reproduction of the racing specifications: from the dimensions of the body and mounting flange to every internal detail that influences the air-fuel mixture, the manufacturing precisely matches the original racing data of the PHBL 25BS (REG.2731), thus guaranteeing a perfect match between physical properties and performance. Designed for high-revving two-stroke engines: The 25mm jet is optimized for tuned, high-revving, small- to medium-displacement (80–125cc) two-stroke engines. The BS version further optimizes the injection curve, ensuring maximum power across the entire rev range while maintaining excellent throttle response. Ultimate tuning platform: "BS" stands for Advanced Tunability. This carburetor typically features a multi-stage adjustable needle valve, a full set of interchangeable jets, and may include a racing accelerator pump. This allows technicians to make millimeter-precise adjustments to track conditions, weather, and engine condition. Restoring or improving peak performance: On vehicles that were originally equipped with this carburetor, this product can directly replace worn or damaged parts, restoring original performance. On tuned motorcycles, it provides a powerful power boost. Guaranteed reliability: High-quality materials ensure stable operation even under demanding racing conditions (high loads and strong vibrations). Precise manufacturing processes guarantee consistent and reproducible tuning results. Compatibility information: Suitable for vehicles or engines originally equipped with a DELL'ORTO PHBL 25BS carburetor with registration number REG.2731. Typical applications: Commonly used on high-performance two-stroke racing motorcycles (e.g., some small off-road motorcycles), racing scooters (e.g., some Aprilia and Piaggio models), kart engines, and small race car engines. Important note: REG.2731 is the primary identifier for the adjustment parameters of this carburetor. You must check the model and registration number of your original carburetor or the engine you intend to equip before purchasing. This model is compatible with two-stroke engines equipped with carburetors. The package contains 1 PHBL 25BS carburetor body (REG.2731).
