Engine oil
Engine oil level measurement
1. Place the machine on a level surface.
2. Warm up the engine for several minutes and
stop it. Wait at least ten minutes for the oil to
drain back into the crankcase before check-
ing the oil level.NOTE:_ Be sure to wait at least ten minutes until the oil lev-
el settles before checking. _3. Remove the engine oil filler cap and wipe the
dipstick off with a clean rag. Insert the dip-
stick in the filler hole without screwing it in.
4. Remove the dipstick and check the oil level.
5. The oil level should be between the maxi-
mum and minimum marks. If the level is low,
add oil to raise it to the proper level.
6. Install the engine oil filler cap.CAUTION:_ Make sure no foreign material enters the
crankcase. _

4. Remove the engine oil filler cap and then the
drain bolt to drain the oil.CAUTION:_ When removing the drain bolt, the compres-
sion spring, oil strainer and O-ring will fall out.
Take care not to lose these parts. _

Final gear oil measurement
1. Place the machine on a level place.
2. Remove the oil filler bolt and check the oil lev-
el. It should be up to the brim of the hole. If
the level is low, add oil to raise it to the proper
level.CAUTION:
Be sure no foreign material enters the final
gear case. 3. Install the oil filler bolt and tighten it to the
specified torque.
Final gear oil replacement
1. Remove the final gear case cover.
2. Place the machine on a level place.
3. Place a container under the final gear case to
collect the used oil. Tightening torque:

Brake fluid level inspection
Insufficient brake fluid may let air enter the brake
system, possibly causing the brakes to become in-
effective.
Before riding, check that the brake fluid is above
the lower level and replenish when necessary.
Observe these precautions:
1. When checking the fluid level, make sure the
top of the master cylinder is level by turning
the handlebars.
2. Use only the designated quality brake fluid.
Otherwise, the rubber seals may deteriorate,
causing leakage and poor brake perfor-
mance.
3. Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reac-
tion and lead to poor brake performance.
4. Be careful that water does not enter the mas-
ter cylinder when refilling. Water will signifi-
cantly lower the boiling point of the fluid and
may result in vapor lock. Recommended brake fluid: DOT 4
