8-32 Periodic Maintenance and Adjustment
Do not start the engine when cleaning the
exhaust system.
Valve Clearance
The correct valve clearance changes with
use, resulting in improper fuel-air supply or
engine noise. To prevent this, the valve
clearance must be adjusted regularly. This
adjustment however, should be left to a
professional service technician.
Front Brake Pad Check
Each brake pad is provided with wear
indicator grooves, which allow you to check
the brake pad wear without having to
disassemble the brake system. To check the
brake pad wear, check the wear indicator
grooves. If a brake pad has worn to the point
that the wear indicator grooves have almost
disappeared, have a service center replace
the brake pads as a set.

NOTE:
The wheels need to be removed to check the
brake pads. (See pages 8-41-8-42 for wheel
removal and installation procedures.)
