This PWK series flat slide racing carburetor is a professional-grade aftermarket component engineered for 2-stroke and 4-stroke powertrains. It is designed as a high-performance upgrade over stock carburetors, delivering sharper throttle response and more efficient fuel atomization to unlock engine power output.
Widely used by motorcycle repair shops, racing teams, parts distributors and resellers globally, it fits a broad range of off-road and on-road small power vehicles. Precision-machined from high-strength aluminum alloy, it ensures stable fuel delivery under variable riding conditions and long service life even in harsh off-road environments.
Key Features
Racing-Grade Flat Slide Structure: Compared with traditional round slide carburetors, the flat slide design reduces intake resistance and achieves faster throttle response, bringing immediate power delivery for acceleration and climbing scenarios.
Full Tuning Adjustability: Equipped with an external idle adjustment knob and replaceable main jet / needle jet set, allowing precise air-fuel ratio tuning to adapt to different altitudes, temperatures and engine modifications.
Multiple Caliber Options: Available in 24mm / 26mm / 28mm / 30mm / 32mm / 34mm venturi sizes, matching 50cc to 250cc engines to cover most common small-displacement models.
Durable Build Quality: High-density aluminum alloy body with anodized red top cap, featuring good wear resistance and corrosion resistance; internal components are precision machined for consistent fuel mixing performance.
Universal Direct Fit: Standard mounting interface and intake manifold size, compatible with most 2-stroke and 4-stroke engine models, no extra modification required for installation.
