Is the rocker arm bracket of scooter divided into positive and negative parts?

The rocker arm bracket of scooter is divided into positive and negative parts.

If you mean the valve rocker arm, then most motorcycle rocker arms are left and right, but after reinstalling or replacing the valve rocker arm, check and adjust the valve clearance again.

After the rocker arm and other parts are installed on the new rocker arm seat, the valve clearance should be readjusted, and attention should be paid to whether the rocker arm and rocker arm shaft are abnormally worn and whether they cooperate well with the new rocker arm seat after being installed on the new rocker arm seat.
