1. Oil level measurement
a. Place the motorcycle on the center-
stand. Warm up the engine for several
minutes.EUU03901NOTE:
Be sure the motorcycle is positioned
straight up when checking the oil level. A
slight tilt toward the side can result in false
readings.b. With the engine stopped, wait a few
minutes and then remove the oil level
gauge.
c. Wipe the oil level gauge off with a
clean rag and insert it in the filler hole
without screwing it in.

e. Fill engine with oil through the oil
level gauge hole.EUU47700cC9Do not put in any chemical additives or
use oils with a grade of “CD (for Diesel
engine)” or higher. Also, be sure not to
use oils labeled “ENERGY CONSERVING
II” or higher. Engine oil also lubricates
the clutch and additives could cause
clutch slippage.
9Be sure no foreign material enters the
crankcase.f. Start the engine and warm up for a
few minutes. While warming up check
for oil leakage. If oil leakage is found,
stop the engine immediately, and ask
a Yamaha dealer to check the cause.
