AILED MAINTENANCE PROCEDURES
Proper engine lubrication is critical to the life and performance your vehicle’s engine. AMERICAN
IRONHORSE engines run best with 20W50 rated oil. For extremely low operating temperatures, (below 40° F.)
10W40 may be used.
Change oil at recommended service intervals. In colder weather, dusty road conditions or generally more
demanding conditions, it is recommended that engine oil be changed more frequently.
Under normal operating conditions, slight water vapor in the crankcase is expelled through the
breather port. However, operation in extremely cold ambient conditions or riding in short runs may not allow
the engine oil to heat up to the point of passing water vapor thereby retaining it in the crankcase. Such
occurrences may block oil flow in the lines and create sludge in the crankcase.
WARNING:
CHANGE THE OIL MORE FREQUENTLY THAN NORMAL SERVICE INTERVALS IN COLD WEATHER USE.
ENSURE THAT CRANKCASE OIL IS THOROUGHLY HEATED BEFORE DRAINING TO ENSURE COMPLETE
REMOVAL OF ALL ACCUMULATED WATER.
