1.5 ENGINE OIL AND FILTER
GENERAL
The engine oil level can be checked with the oil and engine at
ambient temperatures (cold check).
However, an accurate reading of the engine oil level can only
be taken with the engine at normal operating temperature (hot
check). Ride motorcycle for approximately 10 minutes to warm
the oil and the engine to normal operating temperature.
NOTE
The engine will require a longer warm up period in colder
temperatures.
Whether a cold or a hot check, the procedure is the same.
During the pre-ride inspection, at every fueling stop, at sched-
uled maintenance intervals, and when storing the motorcycle:
• Check for oil leaks from the oil filter and oil lines.
• Check the engine oil level (cold check).
• Check engine oil level (hot check).
NOTES
• Engine oil and filter should be changed when fluids are
hot.
• The colder the weather, the shorter the recommended oil
change interval. A vehicle used only for short runs in cold
weather must have the engine oil drained more frequently.
ENGINE OIL LEVEL CHECK
Do not operate the engine when the oil level is below the
add mark on the dipstick at operating temperature. Engine
damage will result. (00187b)
Do not overfill oil tank. Doing so can result in oil carryover
to the air cleaner leading to equipment damage and/or
equipment malfunction. (00190a)
Do not switch lubricant brands indiscriminately because
some lubricants interact chemically when mixed. Use of
inferior lubricants can damage the engine. (00184a)
1. The motorcycle must be on level ground, on the sidestand,
with the engine off.
2. See Figure 1-4 . Unscrew and remove dipstick from oil
tank/swingarm filler hole. Wipe dipstick clean.
3. Insert dipstick into oil tank filler hole, screwing dipstick in
completely. DO NOT OVER TIGHTEN.
NOTE
The area between the upper and lower registration marks is
the operating range.
4. See Figure 1-5 . Unscrew and remove dipstick and read
oil level.
5. If the level is below the lower registration mark, add only
enough oil to bring oil level between lower and upper
registration marks.

3. Using a 5/8 in. wrench, remove drain plug from under oil
tank/swingarm.
