Two-piece intake manifold connection assembly for Yamaha XS650 models 1978-1983, replaces the original 3G1 high temperature gasket.--BIEMMEDUE

This product is an original equipment manufacturer (OEM) replacement parts kit for the Yamaha XS650 (models 1978–1983), specifically designed to manufacturer specifications. It contains two intake manifold fittings (also known as intake hoses) for the left and right cylinders of the engine, exactly matching the OEM part numbers with the prefix "3G1-". Manufactured from a special composite material superior to conventional rubber, it provides a reliable, durable, and cost-effective solution for repairing the intake manifold gasket system of the classic XS650. This system is prone to hardening, cracking, and leaking due to age. This kit restores the full power and smooth running of this legendary twin-cylinder engine. Key features: Specifically designed for classic models: This kit is compatible with Yamaha XS650 models from 1978 to 1983 and is an essential component for the repair and maintenance of this classic motorcycle. Original part number matches original part number: Replaces the original part number prefixes on the intake manifold connections (e.g., the common part number 3G1-13586-00), ensuring a perfect fit in terms of dimensions and angle to the carburetor outlet (usually BS34 or Mikuni) and the cylinder head intake. Improved material, increased durability: Our selected synthetic rubber compound offers excellent heat resistance (suitable for high engine temperatures), superior corrosion resistance to fuel and oil vapors, and better resistance to permanent deformation. It is designed to provide a more durable and stable seal than the original parts. Restoring twin-cylinder fit: On twin-cylinder engines, the intake manifold gasket seal is critical. This set ensures balanced intake conditions for both cylinders thanks to two connections of identical quality. This is fundamental for a stable idle, linear throttle response, and the characteristic twin-cylinder sound. Compatibility information: Compatible models: Yamaha XS650. Compatible model years: 1978, 1979, 1980, 1981, 1982, 1983.
