2-9VALVE CLEARANCE ADJUSTMENT INSPADJNOTE:NOTE:VALVE CLEARANCE ADJUSTMENT Valve clearance adjustment should be madeon a cold engine, at room temperature. When the valve clearance is to be measuredor adjusted, the piston must be at top deadcenter (TDC) on the compression stroke.1. Drain: Coolant2. Remove: Cylinder head coverRefer to “CYLINDER HEAD” in CHAPTER 5. Timing plug3. Measure: Valve clearanceOut of specification Adjust.Valve clearance (cold)Intake valve0.11 0.20 mm(0.0043 0.0079 in)Exhaust valve0.21 0.25 mm(0.0083 0.0098 in)Checking steps: Turn the crankshaft clockwise. When piston #4 is at TDC on the compressionstroke, align the TDC mark a on the A.C.magneto rotor with the mark b on the A.C.magneto cover. Turn the crankshaft clockwise.TDC on the compression stroke can be foundwhen the camshaft lobes are turned away fromeach other. Measure the valve clearance with a thicknessgauge 1 .
