Keihin PWK 28mm Carburetor 016-141 - Suzuki RM85 2002-2026

Product Description

Upgrade your Suzuki RM85's true power potential with the Keihin PWK 28mm carburetor upgrade, engineered to deliver sharper throttle response, stronger acceleration, and improved power delivery across the entire RPM range. The Keihin PWK 28mm carburetor is trusted as standard equipment on many competitive 85cc motocross bikes, making it a proven performance upgrade for riders looking to outperform the stock RM85 setup. Designed for optimized airflow and precise fuel atomization, this carburetor transforms low-end pull and high-RPM power on the track.

The Keihin PWK 28mm carburetor features advanced internal vent design and Air Striker technology to improve signal strength directly at the needle nozzle. This eliminates hesitation and enhances throttle control after hard landings and rough sections. Built with a chromed semi-flat D-throttle valve, it provides maximum air delivery without flex or stickiness. With widely available Keihin tuning components, dialing in your fuel mixture for ambient temperature or elevation changes remains straightforward and precise.

Expert Pro-Tip: When installing a new carburetor on a 2-stroke mini, always verify your cable freeplay and intake boot sealing before firing it up. Spraying a light mist of contact cleaner around the intake manifold interface while idling will help you spot air leaks immediately—if the RPM changes, tighten your clamp or replace the boot gasket to avoid running lean.
