Compatible with Yamaha XJ1100 XS1100 XS1100L XS1100S intake manifold mounting kit, high-density and oil-resistant rubber gasket, replacement part according to original specifications.--DTEKGAZ

【Perfect Compatibility with Classic Four-Cylinder Engines】 Specifically designed for the classic Yamaha four-cylinder motorcycles Yamaha XJ1100 and XS1100 (standard, XS1100L, and XS1100S versions). This product provides a complete set of intake manifold gaskets precisely matched to the structure of these four-cylinder engines, ensuring a perfect seal at each cylinder's intake interface. It is an essential component for eliminating leaks in the intake system of these legendary models. 【Key Function and Impact on Performance】 As the central, flexible gasket connecting the carburetor base (or throttle body) to the cylinder head's intake port, its integrity directly determines the intake system's sealing performance. Old, worn, or hardened gaskets can lead to air leaks, disrupting the optimal air-fuel mixture and causing cold-start problems, significant idle fluctuations, poor acceleration, increased fuel consumption, and unusual engine vibrations. Replacing the original gaskets with this product effectively restores smooth running, responsiveness, and engine performance. 【Reinforced Materials for Classic Models】 Made from high-quality, special synthetic rubber that is resistant to fuels, high temperatures, and ozone. The formula is optimally matched to the fuel components and operating conditions of classic motorcycles. The material features excellent elasticity and long-lasting dimensional stability, withstanding high temperatures and engine vibrations over extended periods. It offers a more reliable and durable sealing solution than conventional rubber. 【Solves Common Problems】 Effectively corrects system-related intake leaks caused by aging, shrinkage, and cracking of the original gaskets. Significantly improves engine idle stability and eliminates unnecessary RPM fluctuations. Restores linear throttle response and improves low- and mid-range torque. Protects the engine from overheating due to prolonged lean running. [Installation and Maintenance Instructions] This is a complete kit for four-cylinder engines. When replacing the intake manifold, it is recommended to remove the entire assembly and replace all four ports simultaneously to ensure an optimal seal for each cylinder. Before installation, all metal contact surfaces must be thoroughly cleaned with appropriate tools to remove any gasket residue, rust, or oil contamination. Tighten the mounting bolts evenly in a crisscross pattern during installation, observing the torque and tightening sequence specified in the manufacturer's service manual. This is essential to prevent deformation and ensure a lasting seal. [Applicable Models] Yamaha XJ1100, Yamaha XS1100, Yamaha XS1100L, Yamaha XS1100S
