WINTER LUBRICATION
In colder climates, the engine oil should be changed often. If
motorcycle is used frequently for short trips, less than 15
miles (24 kilometers), in ambient temperatures below 60°
F (16° C), oil change intervals should be reduced to 1500
miles (2400 kilometers). Motorcycles used only for short runs
must have a thorough tank flush-out before new oil is put in.
The tank flush-out should be performed by an authorized dealer
or qualified technician.
NOTE
The further below freezing the temperature drops, the shorter
the oil change interval should be.
Water vapor is a normal by-product of combustion in any
engine. During cold weather operation, some of the water vapor
condenses to liquid form on the cool metal surfaces inside the
engine. In freezing weather this water will become slush or ice
and, if allowed to accumulate too long, may block the oil lines
and cause damage to the engine.
If the engine is run frequently and allowed to thoroughly warm
up, most of this water will become vapor again and will be
blown out through the crankcase breather.
If the engine is not run frequently and allowed to thoroughly
warm up, this water will accumulate, mix with the engine oil
and form a sludge that is harmful to the engine.
