Help, how to adjust the valve of CBT two-cylinder motorcycle? Better be more detailed ~! Can you help me?

Open the cylinder head cover and manhole cover on the left side of the engine, and turn the crankshaft to align it with the TL line. At this time, the clearance on the camshaft is parallel to the plane of the cylinder head. When the valve of the left cylinder is in a relaxed state, it is the compression top dead center of the left cylinder. Then, adjust the valve clearance to 0.05-0.08 mm, and then rotate the magneto to align it with the TR line. When the rocker arm of the right cylinder valve is in a relaxed state, adjust the valve clearance of the right cylinder according to the above method. After adjustment, repeat the above actions and check that there is no abnormality.
