Short Description: Restore your engine's compression and thermal efficiency with this precision-cast Cylinder Head Assembly. A vital upgrade for any restoration, ensuring optimal combustion and reliable cooling for the heavy-duty Dnepr MT-11.

Technical Specifications:

• Compatibility: Dnepr MT-11 (and compatible 649cc models)
• Manufacturer Code / SKU: MT8015-3-01 / MT8015-4-01
• Part Type: Engine / Valve Timing Gear

Purpose and Role in the Motorcycle (based on the original manual):
The cylinder head is a cornerstone of the engine's upper assembly, serving as the ceiling of the combustion chamber. Cast from high-duty aluminium alloy, these heads feature a hemispherical combustion chamber and extensive external finning designed to dissipate heat through counter air flow. Their primary role is to house the valve timing gear, providing secure brackets for the rockers and a threaded port for the spark plug. Proper functioning of the head is essential for maintaining the correct rocker-to-valve clearance ($0.07\text{ mm}$) and ensuring a leak-proof seal against the cylinder. Signs that it is time to inspect or replace the head assembly include significant carbon buildup in the chambers (which can cause engine knocking), loss of compression due to warped seating surfaces, or failure of the valves to remain air-tight during the kerosene seepage test.

Benefits of Buying:

• Exact Technical Fit: Manufactured to the original specifications of the MT11 Owners Maintenance manual, ensuring perfect alignment with anchor studs and the cylinder recess.
• Enhanced Thermal Management: High-quality aluminium alloy casting with optimized fins to prevent overheating and power loss during heavy-load operation.
• Restored Engine Efficiency: Provides a fresh, clean surface for valve seating and spark plug installation, directly improving combustion and fuel consumption.
