Prairie 360 KVF-360 Engine Top End - Valve Clearance Inspection
NOTE: Check the valve clearance only when the engine is cold (at room temperature).
- Preparation:
- Ensure the engine is cold.
- Disassembly:

- Crankshaft Positioning:
- Rotate the crankshaft to Top Dead Center (TDC) of the compression stroke.
- Measurement:
- Use a thickness gauge to measure the clearance of each valve between the end of the valve stem and the adjusting screw on the rocker arm.
- Refer to the specified clearance values for both exhaust and inlet valves when the engine is cold.
- Adjustment:
- If the measured clearance is not within the specified range, adjustments are necessary.
- Follow the manufacturer's guidelines for adjusting the valve clearance to ensure proper engine operation.
Valve Clearance (when cold)
- Exhaust: 0.15 ~ 0.20 mm (0.0059 ~ 0.0079 in.)
- Inlet: 0.08 ~ 0.13 mm (0.0032 ~ 0.0051 in.)
Regularly inspecting and adjusting valve clearance according to the manufacturer's recommendations will help maintain optimal engine performance and prevent potential issues such as valve damage or poor engine operation.
