Break-In
A brief break-in procedure must be carried out to
obtain the proper operating clearances in the engine
and transmission, which are necessary for perfor-
mance and reliability.
NOTICE
For the first hour or 20 km (12 mi) of opera-
tion, run the engine at low and moderate en-
gine speeds. See details below.
NOTE
○
The low-speed operation during the break-in pe-
riod may cause carbon to build up on and foul
the spark plug. If so, replace the standard spark
plug with a hotter spark plug for the duration of the
break-in period.
