How to Adjust the Valves on CFMoto NK150?

[MarianaDella]

Both the fairings and fuel tank need to be removed, but the radiator can stay in place. Then, take off the exhaust valve cover and remove the fan. First, use a hex wrench to remove the magneto side cover, then unscrew the timing inspection port screw. Rotate the magneto with a socket wrench to locate the timing marks. When the marks are visible through the inspection port and the engine piston is at top dead center, the timing is correct. Loosen the intake and exhaust valve fixing bolts with a socket wrench, then manually adjust the valve clearance screw. When it can't be turned anymore, slightly loosen it a tiny bit to complete the adjustment.
