How to adjust the four-cylinder balance of Honda CB- 1 motorcycle carburetor

I just dismantled my carburetor and readjusted it through the following steps: 1: Clean all idle passages and oil filling passages. 2. Adjust the valve opening to be consistent. 3: Tighten the mixing ratio screw by 1.8 turns. Then adjust the mixing ratio one by one. Adjust the mixing ratio, first find a high point, and then adjust the remaining three cylinders one by one according to this high point.
