Hi guys could some please advice me on the method of checking the valve clearance on the 150f and what the specs for them are.

Inspect and adjust the valve clearance while the engine is cold (below 35C/95F)
1.Remove the crankshaft hole cap and timing hole cap.
2.Remove valve adjuster hole caps.
3.rotate the crankshaft counterclockwise and align the "T" mark on the flywheel with the index mark on the left crankcase cover. Make sure the piston is at TDC on compression stroke.
4.Check the clearance of the intake and exhaust valves by inserting a feeler gauge between the adjusting screw and the rocker arm.
Valve Clearance: IN/EX:0.10+/-0.02mm(0.004+/-0.001in)
