Valve clearance adjustment

The correct valve clearance changes with
use, resulting in improper fuel/air supply or
engine noise. To prevent this, the valve clear-
ance must be adjusted regularly. This adjust-
ment however, should be left to a professional
Yamaha service technician.

Front brake pad check

Each brake pad is provided with wear indica-
tor grooves, which allow you to check the
brake pad wear without having to disassem-
ble the brake. To check the brake pad wear,
check the wear indicator grooves. If a brake
pad has worn to the point that the wear indica-
tor grooves have almost disappeared, have a
Yamaha dealer replace the brake pads as a
set.
