Short Description: Restore your engine's compression and efficiency with this precision-engineered valve service set. Essential for maintaining the airtightness of the combustion chamber, this kit ensures your Dnepr MT-11 runs smoothly and reliably.

Technical Specifications:

• Compatibility: Dnepr MT-11 (and compatible models in the series)
• Manufacturer Code / SKU: MT801465, MT801466, MT801461
• Part Type: Engine (Valve Timing Gear)

Purpose and Role in the Motorcycle (based on the original manual):
This set is a critical component of the Valve Timing Gear, which manages the precise opening and closing of the inlet and outlet valves in the MT-11's four-stroke, double-cylinder overhead valve (OHV) engine. The valve springs provide the necessary tension to snap the valves shut, ensuring the combustion chamber remains sealed during the compression and power strokes. The upper and lower bearing disks act as buffers to distribute spring pressure evenly, preventing premature fatigue of the valve components. Meanwhile, the valve seals are vital for preventing engine oil from leaking into the cylinder head and combustion chamber. According to the technical manual, the valve system requires inspection every 10,000 km. Signs that it is time to replace these components include a noticeable drop in engine power, excessive oil consumption, or "popping" in the carburetor caused by poor valve seating and air-tightness.

Benefits of Buying:

• Exact Technical Fit: Manufactured to meet the strict specifications of the MT-11 engine, ensuring the correct valve timing and a cold engine clearance of 0.07 mm.
• Restored Engine Compression: New springs and seals eliminate air leaks and oil seepage, significantly improving fuel efficiency and horsepower.
• Extended Engine Life: By preventing "valve float" and oil contamination in the cylinders, this kit reduces carbon deposits on piston heads and valves, extending the interval between major overhauls.
