EBU20682Engine break-in TIP
For ATVs equipped with an odometer or an hour
meter, follow the figures given in km (mi) or the
figures given in hours.
For ATVs not equipped with an odometer or
hour meter, follow the figures given in hours.There is never a more important period in the life of

cessive load on it for the first 320 km (200 mi) or 20
hours. The various parts in the engine wear and
polish themselves to the correct operating clear-
ances. During this period, prolonged full-throttle
operation or any condition that might result in en-
gine overheating must be avoided. 0
– 160 km (0 –100 mi) or 0 –10 hours

the speed of the ATV regularly. Do not operate it at
one set throttle position.

Avoid prolonged operation above 3/4 throttle. Rev
the engine freely, but do not use full throttle at any
time.
