How to adjust the valve clearance of Yamaha motorcycle

Open the left gearbox cover, and then align the T-notch of the magneto with the notch on the gearbox. When the engine is in the compression stroke, this is just at the top dead center. If this is the exhaust stroke, you can turn it again. Then unscrew two large screws with a diameter of 2 cm on the cylinder head. At this time, you can see the rocker tail and valve stem of exhaust valve and intake valve. Tighten the screw at the end of the valve stem to adjust the valve clearance. When the clearance is measured with a feeler gauge, the cold clearance of the intake valve is almost 0.08-0. 10MM, and that of the exhaust valve is almost 0. 10-0. 12 mm. ..
