In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives. Do not
use oils with a diesel specification of “CD”
or oils of a higher quality than specified. In
addition, do not use oils labeled “ENERGY
CONSERVING II” or higher.


Make sure that no foreign material enters
the crankcase.

Coolant
The coolant level should be checked before each
ride.
Checking the coolant level
1. Place the vehicle on a level surface.
2. Open the hood. (See pages 8-17–8-19 for
hood opening and closing procedures.)
3. Check the coolant level in the coolant reser-
voir when the engine is cold as the coolant
level varies with engine temperature.NOTE:_ The coolant should be between the minimum and
maximum level marks. _4. If the coolant is at or below the minimum level
mark, remove the reservoir cap, add coolant
to the maximum level mark, install the reser-
voir cap, and then close the hood.
Coolant reservoir capacity
(up to the maximum level mark):
0.35 L (0.31 Imp qt, 0.37 US qt)

Inspection
The spark plug is an important engine component
and is easy to inspect. The condition of the spark
plug can indicate the condition of the engine.
The ideal color of the porcelain insulator around
the center electrode is a medium-to-light tan for a
vehicle that is being ridden normally.
Do not attempt to diagnose such problems your-
self.
Instead, take the vehicle to a Yamaha dealer. You
should periodically remove and inspect the spark
plug because heat and deposits will cause the
spark plug to slowly break down and erode. If elec-
trode erosion becomes excessive, or if carbon and
other deposits are excessive, you should replace
the spark plug with the specified plug.
Specified spark plug:
