Operation

throttle to 3000 r/min or less.

3.Next two hours:

Accelerate at full throttle onto plane, then reduce engine speed to three-quar- ter throttle (approximately 4000 r/min). Vary engine speed occasionally. Run at full throttle for one minute, then allow about 10 minutes of operation at three- quarter throttle or less to let the engine cool.

4.Remaining seven hours:

Run the engine at any speed. However, avoid operating at full throttle for more than 5 minutes at a time.

5.After the first 10 hours:

Operate the engine normally. Use only straight gasoline in the fuel tank. The Yamaha oil injection system provides

proper lubrication for normal operation.
