📋 Product Overview

This product is a Yamaha 100 Cylinder Gasket Set, part number MIYP100-5063. It is a replacement cylinder gasket set designed for LY149QMG engines — essential sealing components for engine overhauls or cylinder repairs.

This set includes two critical gaskets: the cylinder base gasket and the cylinder head gasket. The cylinder head gasket seals the joint between the cylinder head and cylinder body, preventing high-pressure combustion gas leakage and coolant/oil cross-contamination. The cylinder base gasket seals the joint between the cylinder body and the crankcase. These gaskets are used on a wide variety of scooter and ATV brands and models equipped with the 149QMG engine. Manufactured from heat-resistant, compression-resistant materials, they ensure long-term sealing reliability.

✅ Quality Assurance: Manufactured to exact original specifications. Gasket thickness, shape, and mounting hole positions match OEM parts for a perfect fit and reliable sealing.

⚙️ Product Features

🔩 Precision Stamped: Manufactured using precision dies for accurate dimensions and mounting hole alignment — perfect fit against cylinder and cylinder head surfaces.
🌡️ Heat-Resistant Material: High-quality heat-resistant composite or metal materials withstand the engine's high-temperature, high-pressure operating environment.
🛡️ Reliable Sealing: Optimized gasket design and material ensure proper separation of high-pressure combustion gases, engine oil, and coolant — no cross-contamination.
🔧 Complete Set: Includes both cylinder head gasket and cylinder base gasket — covers all sealing needs for engine overhauls.
🔄 Direct Replacement: Gasket thickness and dimensions match OEM — installs without any modifications.

✅ Typical Signs That Cylinder Head Gasket Replacement Is Needed:
• Coolant level drops without visible external leaks — bubbles in the radiator (combustion gas entering cooling system).
• Engine oil appears milky or foamy (coolant mixing with oil).
• White smoke from exhaust (coolant entering combustion chamber).
• Engine power loss — low compression.
• During engine overhaul or cylinder replacement, gaskets must be replaced.
Replacing a damaged cylinder head gasket promptly prevents engine overheating, power loss, and component damage.

✅ Installation Tips:
1. When removing the cylinder head, take care not to damage the gasket mating surfaces.
2. Before installation, thoroughly clean the cylinder head, cylinder body, and crankcase mating surfaces — remove all old gasket residue and oil.
3. Install new gaskets with correct orientation and alignment — ensure all mounting holes are properly positioned.
4. Tighten cylinder head bolts in the OEM cross-pattern sequence in 2-3 even stages to specified torque.
5. After installation, start the engine and check for any gas or fluid leaks.
Professional installation by a qualified technician is strongly recommended. Improper head gasket installation may cause severe gas leakage or engine damage.
