Engine break-in
There is never a more important period in the
life of your machine than the period between
zero and 20 hours.
For this reason, we ask that you carefully read
the following material. Because the engine is
brand new, you must not put an excessive
load on it for the first several hours of running.
During the first 20 hours, the various parts in
the engine wear and polish themselves to the
correct operating clearances.
During this period, prolonged full throttle oper-
ation or any condition which might result in
excessive engine heating must be avoided.
However, momentary (2-3 seconds maximum)
full throttle operation under load does not
harm the engine. Each full throttle accelera-
tion sequence should be followed with a sub-
stantial rest period 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
minutes 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.
