PWK 38mm Flat Slide Carburetor for 400cc 500cc Dirt Bike ATV

Product Overview

This PWK 38mm flat slide carburetor is built for 400cc–500cc high-performance dirt bikes, ATVs, quads, UTVs, and racing off-road machines. It is a common choice for riders who want stronger airflow, quicker fuel response, and improved power delivery on larger modified engines.

Compared with smaller sizes, the 38mm version is better suited for engines that can use more air at higher RPM. It is especially useful for aggressive riding, racing quads, and high-output builds where throttle response and top-end breathing are important.
