Short Description: Restore your engine's compression and peak performance with this professional-grade set of inlet and outlet valves. Engineered for durability and precise sealing, these valves are essential for maintaining the power and efficiency of your Dnepr MT-11.

Technical Specifications:

• Compatibility: Dnepr MT-11 (KM3 series) and compatible models
• Manufacturer Code / SKU: MT801523 / KM3-8.15201530
• Part Type: Engine / Valve Timing Gear

Purpose and Role in the Motorcycle (based on the original manual):
The inlet and outlet valves are the "lungs" of the Dnepr MT-11's double-cylinder, four-stroke overhead valve (OHV) engine. Their primary role is to regulate the flow of the air-fuel mixture into the combustion chamber and the timely expulsion of exhaust gases. In the MT-11, these valves are actuated by a system of camshafts, tappets, and rockers. Proper seating and timing of these valves are critical; according to the technical manual, a cold engine must maintain a precise rocker-to-valve clearance of 0.07 mm. When valves wear out or lose their airtight seal, the engine suffers from a loss of compression, reduced power, and erratic idling. Signs that it is time for replacement or grinding include failing the "kerosene leak test" (where fuel seeps through the valve seat in under 10 seconds) or hearing popping sounds in the carburettors.

Benefits of Buying:

• Exact Factory Specifications: Manufactured to match the original KM3 engine dimensions, ensuring a perfect fit within the cylinder head guides.
• Restored Engine Compression: Replacing worn valves eliminates gas leakage, directly increasing the engine's volumetric efficiency and overall horsepower.
• High-Temperature Resilience: Built from heat-resistant alloys to withstand the intense thermal loads of the MT-11's air-cooled combustion chambers, extending the interval between overhauls.
