Turn the crankshaft counterclockwise and alian the "T" mark with the index notch on the left crank case

Install the dowel pin

Install the cam chain on the cam sprocket

Install the cam sprocket aligning its "O" mark with the index notch on the cylinder head.

Tighten sprocket bolts to 6.5 lbs-ft

Valve clearance
Intake & Exhaust = 0.05 mm (0.002 in)
