PWK 40mm Flat Slide Carburetor for 500cc 650cc Dirt Bike ATV

Product Overview

This PWK 40mm flat slide carburetor is designed for big-bore 500cc–650cc dirt bikes, ATVs, quads, UTVs, and high-output off-road builds that require serious airflow. The 40mm size is best suited for engines with enough displacement and modifications to benefit from a larger carburetor.

With its flat-slide structure, this carburetor helps provide a direct airflow path and fast fuel response for high-RPM riding. The anodized aluminum alloy body is made for heat, vibration, dust, and demanding riding conditions, making it a strong option for large-displacement performance builds.
