Valve Clearence Measurement steps:

turn the starter pully conuterclockwise with a wrench

Vlave clearence must be measeured when the engine is cold to touch

Allign the "T" mark on the fiywheel with the stationary pointer on the crankecase cover When the "T" mark is aligned with the stationary pointer the piston is at top dead center (TDC)

Measure the valve clearence using a feeler gauge

intake 0.05 - 0.09mm (0.002-0.004 in)

exhaust 0.11-0.15 mm (0.004 - 0.006 in)

Where is the VIN far a Yamaha moto4?

If you're sitting on the 4-wheeler, it is on the bottom of the left side of the frame, just in front of the footrest at the same height. It's small, so you'll have to really clean that area.
