Valve clearance adjustment

The correct valve clearance changes with use, resulting in

improper fuel/air supply or engine noise. To prevent this,

valve clearance must be adjusted regularly. This adjustment,

however, should be left to a professional Yamaha service

technician.

Carburetor adjustment

The carburetor is a vital part of the engine. Adjusting should

be left to a Yamaha dealer who has the professional

knowledge, specialized data, and equipment to do so

properly. However, the following may be serviced by the

owner as part of routine maintenance.

CAUTION:

The carburetor was set at Yamaha factory after many

tests. If the settings are changed, poor engine

performance and damage may result.
