Short Description: Restore your engine's compression and breathing efficiency with this high-quality set of inlet and outlet valves. These original-specification components are essential for returning your Dnepr MT-11 to its peak operating power and fuel economy.

Technical Specifications:

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

Purpose and Role in the Motorcycle (based on the original manual):
The inlet and outlet valves are critical components of the engine's valve timing gear, acting as the "gates" for the combustion process. The inlet valves allow the air-fuel mixture to enter the cylinder, while the outlet valves expel exhaust gases. According to the technical manual, these parts must maintain a precise rocker-to-valve clearance of 0.07 mm (on a cold engine) to ensure the cylinder fills correctly and the valves seal tightly. When these valves wear down or their seats become pitted, the engine suffers from a loss of compression, leading to a significant drop in power, irregular idling, or "popping" in the carburetor. The manual recommends inspecting these valves for airtightness every 10,000 km; if kerosene seeps through the valve seat in less than 10 seconds, replacement or professional grinding is required to prevent permanent damage to the cylinder head.

Benefits of Buying:

• Exact Fit to Specifications: Manufactured to meet the original KM3 engine requirements, ensuring seamless integration with your rockers and valve springs.
• Optimized Engine Compression: Replacing worn valves restores the airtight seal of the combustion chamber, directly increasing torque and overall engine efficiency.
• Long-term Reliability: By using a complete set of four valves, you ensure balanced airflow and consistent timing across both cylinders, reducing uneven wear on the camshaft and tappets.
