Engine Break-In; Parking - Yamaha VINO YJ50RS Owner's Manual

Engine break-in

There is never a more important period
in the life of your engine than the period
between 0 and 1,000 km (600 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1,000 km (600 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
0–150 km (0–90 mi)
G
Avoid prolonged operation above
1/3 throttle.
G
After every hour of operation, stop
the engine, and then let it cool for
five to ten minutes.
G
Vary the engine speed from time to
time. Do not operate the engine at
one set throttle position.
