EBU33702Engine oil and oil filter cartridgeCheck engine oil level before each operation.
In addition, change the oil and the oil filter car-
tridge at the intervals specified in the periodic
maintenance and lubrication chart.
To check the engine oil level
1. Park the vehicle on a level surface.
2. Check the engine oil level on a cold en- gine.TIPIf the engine was started before checking the
oil level, be sure to warm up the engine suffi-
ciently, and then wait at least 10 minutes until
the oil settles for an accurate reading. 3. Remove the passenger seat cushion (seepage 4-15 for more information).
4. Remove the rubber cover. 5. Remove the engine oil dipstick and wipe
it with a clean rag.

TIPBe sure to wipe off spilled oil on any parts af-
ter the engine and exhaust system have
cooled down. NOTICEECB00301In 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 la-
beled “ENERGY CONSERVING II” or
higher.
Make sure that no foreign material en-
ters the crankcase. 14. Start the engine, and then let it idle for
several minutes while checking it for oil
leakage. If oil is leaking, immediately turn
the engine off and check for the cause.

15. Turn the engine off, wait at least 10 min-utes, and then check the oil level and cor-
rect it if necessary.
16. Install the rubber cover.
17. Install the passenger seat cushion.EBU32370Final gear oilChecking the final gear oil level 1. Park the vehicle on a level surface.
2. Remove the final gear oil filler bolt and its gasket, and then check the oil level in the
final gear case. The oil level should be at
the brim of the filler hole. 3. If the oil is below the brim of the filler hole,
add sufficient oil of the recommended
type to raise it to the correct level.
NOTICE: Be sure no foreign material
enters the final gear case.
[ECB00422]
4. Check the gasket for damage, and re- place it if necessary.
5. Install the oil filler bolt and its gasket, and then tighten the bolt to the specified
torque.1. Final gear oil

8. Check for oil leakage. If oil leakage isfound, check for the cause.EBU32380Differential gear oilChecking the differential gear oil level1. Park the vehicle on a level surface.
2. Remove the differential gear oil filler bolt
and its gasket, and then check the oil lev-
el. It should be up to the brim of the filler
hole. 3. If the level is low, add sufficient oil of the
recommended type to raise it to the
specified level. NOTICE: Be sure no for-
eign material enters the differential
gear case.
[ECB00412]
4. Check the gasket for damage, and re- place it if necessary.
5. Install the differential gear oil filler bolt and its gasket, and then tighten the bolt
to the specified torque.

8. Check for oil leakage. If oil leakage isfound, check for the cause.EBU33660CoolantThe coolant level should be checked before
each ride. In addition, the coolant must be
changed at the intervals specified in the peri-
odic maintenance and lubrication chart.
Checking the coolant level1. Park the vehicle on a level surface.
2. Check the coolant level in the coolant reservoir when the engine is cold as the
coolant level varies with engine tempera-
ture.TIPThe coolant should be between the minimum
and maximum level marks.
3. If the coolant is at or below the minimum
level mark, remove the coolant reservoir
cap, add coolant to the maximum level
mark, and install the reservoir cap.

mum level mark):0.28 L (0.30 US qt, 0.25 Imp.qt)

Clean the filler cap before removing. Use
only DOT 4 brake fluid from a sealed
container.
Use only the specified brake fluid; other-
wise, the rubber seals may deteriorate,
causing leakage.
Refill with the same type of brake fluid.
Adding a brake fluid other than DOT 4
may result in a harmful chemical reac-
tion.
Be careful that water does not enter the
brake fluid reservoir when refilling. Wa-
ter will significantly lower the boiling
point of the fluid and may result in vapor
lock. NOTICEECB01161Brake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
fluid immediately.
As the brake pads wear, it is normal for the
brake fluid level to gradually go down. A low
brake fluid level may indicate worn brake
pads and/or brake system leakage; therefore,
be sure to check the brake pads for wear and
the brake system for leakage. If the brake fluid
level goes down suddenly, have a Yamaha
dealer check the cause before further riding.EBU32520Brake fluid replacementComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during periodic maintenance or
when they are damaged or leaking.
Replace the oil seals every two years.
Replace the brake hoses every four years.EBU32530Checking the brake pedalHave a Yamaha dealer check the brakes at
the intervals specified in the periodic mainte-
nance and lubrication chart. There should be
