BREAKING IN ENGINE
Your new engine requires a period of
break-in to allow mating surfaces of mov-
ing parts to wear in evenly. Correct break-
in will help ensure proper performance
and longer engine life.

Failure to follow the break-in procedure
could result in reduced engine life or
even severe engine damage.
8
Premix fuel must be used during break-
in in addition to oil in the oil injection
system.
8
After break-in, use gasoline only. If pre-
mix fuel is used continuously, the oxy-
gen sensor for the Electronic Fuel
Injection system could be damaged.
