MEASURING THE ENGINE OIL PRESSURE
1. Check:
• Engine oil level
Below the minimum level mark → Add the
recommended engine oil to the proper level.
2. Start the engine, warm it up for several min-
utes, and then turn it off.
ECA13410
When the engine is cold, the engine oil will
have a higher viscosity, causing the engine
oil pressure to increase. Therefore, be sure
to measure the engine oil pressure after
warming up the engine.
3. Remove:
• Right side cowling
Refer to “GENERAL CHASSIS” on page 4-1.
4. Remove:
• Main gallery bolt
EWA12980
The engine, muffler and engine oil are ex-
tremely hot.
5. Install:
• Oil pressure gauge set “1”
• Oil pressure adapter B “2”
6. Measure:
• Engine oil pressure
(at the following conditions)
Out of specification → Adjust.
7. Install:
• Main gallery bolt
8. Install:
• Right side cowling
Refer to “GENERAL CHASSIS” on page 4-1.

CHECKING THE COOLANT LEVEL
1. Stand the vehicle on a level surface.
• Place the vehicle on the centerstand.
• Make sure the vehicle is upright.
2. Remove:
• Left side panel
Refer to “GENERAL CHASSIS” on page 4-1.
3. Check:
• Coolant level
The coolant level should be between the min-
imum level mark “a” and maximum level mark
“b”.
Below the minimum level mark → Add the
recommended coolant to the proper level.
