Measuring The Engine Oil Pressure - Yamaha FJR 1300 AE 2014 Service Manual

b. Slightly loosen the engine oil check bolt "1".
c. Start the engine and keep it idling until engine
oil starts to seep from the engine oil check
bolt. If no engine oil comes out after one
minute, turn the engine off so that it will not
seize.
d. Check the engine oil passages, the oil filter
cartridge and the oil pump for damage or
leakage.
Refer to "OIL PUMP" on page 5-59.
e. Start the engine after solving the problem(s)
and check the engine oil pressure again.
f. Tighten the engine oil check bolt to specifica-
tion.

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.

NOTICE
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.
