JASO T 903 standard
The JASO T 903 standard is an index for engine
oils for 4-stroke motorcycle engines.
There are two classes: MA and MB.
Oil conforming to the standard is labeled on the oil
container. For example, the following label shows
the MA classification.
1. Run the engine at idle for 3 minutes, then shut
it off.
2. Wait 3 minutes after shutting off the engine to
allow the oil to properly distribute itself in the
engine.
3. Support the CRF in an upright position on a
level surface.
4. Remove the engine oil fill cap/dipstick (1),
wipe it clean, and insert the engine oil fill cap/
dipstick without screwing it in. Remove the
engine oil fill cap/dipstick.
5. Check that the oil level is between the upper
(2) and lower (3) level marks on the engine oil
fill cap/dipstick.
• If the oil is at or near the upper level mark,
you do not have to add oil.
• If the oil is below or near the lower level
mark, add the recommended oil until it
reaches the upper level mark. (Do not
overfill.)
Reinstall the engine oil fill cap/dipstick.
Repeat steps 1–5.
6. Reinsert the engine oil fill cap/dipstick.
7. Check for oil leaks.
1. Run the engine at idle for 3 minutes, then shut it
off.
2. Support the CRF in an upright position on a
level surface.
3. Remove the engine oil fill cap/dipstick (1)
from the left crankcase cover.
4. Place an oil drain pan under the engine to catch
the oil. Then remove the engine oil drain bolt
(2) and sealing washer (3).
5. After the oil has drained, apply engine oil to
the drain bolt threads and tighten it with a new
sealing washer to the specified torque:
16 lbf·ft (22 N·m, 2.2 kgf·m)
Pour the drained oil into a suitable container and
dispose of it in an approved manner (page 130).
NOTICE
Improper disposal of drained fluids is harmful to
the environment.
