Yamaha KODIAK Ultramatic Owner's Manual page 61

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 period, consult a Yamaha dealer.
1. 0–10 hours:
Avoid continuous operation above half
throttle. Allow a cooling off period of five
to ten minutes after every hour of opera-
tion. Vary the speed of the machine from
time to time. Do not operate it at one set
throttle position.
2. 10–20 hours:
Avoid prolonged operation above 3/4
throttle. Rev the machine freely but do
not use full throttle at any time.
3. After break-in:
Avoid prolonged full throttle operation.
Vary speeds occasionally.
