Intake Manifold Interface Joint for Yamaha RD350 LC & YFZ350 Banshee | OEM 31K-13565-01

Product Overview

Restore the explosive two-stroke power of your Yamaha with this premium Carburetor Intake Manifold Interface. Specifically engineered for the RD350 LC and the legendary YFZ350 Banshee, this joint is a direct replacement for OEM part #31K-13565-01. On high-performance 2-stroke engines, the intake boot is a critical safety component; a cracked boot allows extra air to enter, causing a "lean condition" that can lead to catastrophic engine seizure. Our high-quality replacement ensures a perfect airtight seal, providing reliable operation and "new engine" throttle response.

Key Features

• Precision Engine Connection: Perfectly bridges the gap between the carburetor and the reed valve cage, ensuring that every drop of fuel-air mixture is delivered efficiently for "new power" performance.
• Premium Material Quality: Crafted from high-quality, lightweight materials that are naturally anti-rust and colorfast. Designed to look good and perform better over long-term use.
• Extreme Durability: Manufactured to withstand the intense vibrations and constant pressure pulses inherent in high-performance 2-stroke engines. Resists the "dry-rot" common in vintage intake boots.
• Safe & Reliable Sealing: Provides a 100% airtight vacuum seal. By eliminating air leaks, it prevents erratic idling and protects your engine's top end from the dangers of running too lean.
• Factory Standard Fit: Strictly follows the 31K-13565-01 specification for a seamless bolt-on installation, ensuring the carburetors sit at the correct factory angle and height.
