Each full throttle acceleration sequence

should be followed with a substantial rest pe-

riod for the engine by cruising at lower r/min

so the engine can rid itself of the temporary

build up of heat.

If any abnormality is noticed during this peri-

od, consult a Yamaha dealer.

0–10 hours:

Avoid continuous operation above half throt-

tle. Allow a cooling off period of five to ten min-

utes after every hour of operation. Vary the

speed of the machine from time to time. Do

not operate it at one set throttle position.

10–20 hours:

Avoid prolonged operation above 3/4 throttle.

Rev the machine freely through the gears but

do not use full throttle at any time.

After break-in:

Avoid prolonged full throttle operation. Vary

speeds occasionally.
