This high-performance carburetor is designed to deliver optimal fuel mixture and airflow to the engine, ensuring it runs efficiently and effectively in varying temperatures and conditions.

The intake system features a high-flow air filter to ensure a clean fuel/air mixture, and the reusable foam filter can be easily cleaned or replaced for improved performance.

The Mikuni TM40 rack carburetor is renowned for its precise fuel mixture control. Mikuni's Flat Slide Throttle Bodies (2670-335) combine an idling circuit, needle jet circuit, main jet circuit, and needle valve assembly to manage fuel flow precisely. High-quality, heat-resistant jets, needle needles, and needle valves are used to ensure reliable performance in cold temperatures. The carburetor kit also includes a set of main and pilot jets for easy tuning and customization (2670-351).

The Mikuni TM40 rack carburetor is designed with easy tuning and adjustments in mind. The needles, needle jets, and main jets can be easily accessed for quick adjustments. Additionally, the fuel level inside the bowl can be checked and adjusted for optimal performance. The kit includes a seed tune kit, which consists of different needle and main jet combinations to aid in setting up your snowmobile for various power delivery preferences and operating conditions.
