With this original 1,90 mm Yamaha valve shim, you set the valve mechanism to the correct clearance on the cylinder head of the Yamaha Neo's 4-stroke. A valve shim is a precision part: its thickness directly determines the valve clearance, which affects engine power, fuel consumption, and wear on the valves and camshafts.
Replace the shim if the measured valve clearance falls outside the manufacturer's tolerance. Always remeasure the valve clearance after installation to confirm that you are within specification. Yamaha OEM quality guarantees dimensional accuracy and the correct hardness for a long service life.
Part number: 5STE-21691-10 (also referred to as 5ste216911 in the feed).
