Short Description: Restore your engine's compression and eliminate costly leaks with this precision-engineered pair of cylinder head gaskets. Essential for maintaining peak performance and ensuring the long-term reliability of your Dnepr MT-11.

Technical Specifications:

• Compatibility: Dnepr MT-11 (and compatible 649cc OHV models)
• Manufacturer Code / SKU: MT801305
• Part Type: Engine / Sealing System

Purpose and Role in the Motorcycle (based on the original manual):
The cylinder head gaskets are critical sealing elements positioned between the bimetallic cylinder barrels and the aluminium alloy cylinder heads. In the Dnepr MT-11's double-cylinder engine, these gaskets must withstand high thermal loads and internal pressures to maintain a perfect seal. Their primary role is to prevent combustion gases from escaping the cylinder (maintaining the 7.0–8.5 compression ratio) and to stop engine oil from leaking into the combustion chambers or out of the engine casing. According to the technical manual, a failure in these gaskets leads to "disturbed air-tightness," which causes immediate oil leakage and leads to premature oil contamination and accelerated wear of internal engine parts. Signs that it is time for replacement include visible oil seepage around the cylinder head, a noticeable drop in engine power, or "missing" cylinders during operation.

Benefits of Buying:

• Exact OEM Fit: Manufactured to the precise specifications required for the MT-11's 78mm bore, ensuring a leak-proof seal.
• Enhanced Engine Longevity: By preventing air infiltration and oil leakage, these gaskets protect your engine from premature contamination and internal wear.
• Restored Combustion Efficiency: High-quality sealing ensures that the maximum amount of combustible mixture remains in the chamber, restoring lost horsepower and fuel efficiency.
