Product Overview

Refresh the heartbeat of your classic inline-four with the GOOFIT 4-Piece Intake Manifold Boot Set. Specifically engineered for the Yamaha XJ900 (1983-1984) and the later XJ900F (1991-1994), this kit is the essential solution for aging, cracked, or hardened intake boots.

On vintage air-cooled engines like the XJ900, the rubber manifolds are exposed to extreme cylinder head heat. Over time, these parts develop vacuum leaks that lead to "hunting" idles, engine hesitation, and difficult cold starts. Our high-quality replacements are designed to handle high-pressure environments, ensuring your engine breathes clean, metered air for a smoother, more powerful ride.

Product Compatibility

Direct replacement for the Yamaha XJ900 series. Please verify your production year and engine configuration.

Key Features

  • Complete 4-Cylinder Refresh: Sold as a full set of 4 pieces, allowing you to replace all intake interfaces at once. This ensures balanced vacuum pressure across the entire carburetor bank, which is vital for perfect engine synchronization.
  • Engineered for High Temperatures: Made from durable, heat-stable materials that won't harden or crack under the intense thermal radiation of a 900cc air-cooled engine.
  • DIY Friendly Installation: Featuring a simple, user-centric design, these boots can be installed quickly without the need for specialized tools or advanced mechanical skills. Perfect for DIY enthusiasts and professional restorers alike.
  • Restores Engine Efficiency: By providing a 100% airtight seal, these boots fix common performance issues such as "lean burn" (backfiring on deceleration) and erratic idling, directly improving fuel economy and throttle response.
  • Long-Lasting Performance: Our strict material selection ensures a long service life, preventing the "dry-rot" common in vintage motorcycle components and maintaining peak operating efficiency.
