Engine oil level measurement
1. Place the machine on a level place.
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 dipstick and wipe it off with a
clean rag. Insert the dipstick in the filler hole
without screwing it in.
4. Remove the dipstick and inspect 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.CAUTION:_ Make sure no foreign material enters the
crankcase. _

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
