Honda GL1800 Setup Instructions page 18

17. Check the final drive gearbox
oil level.
Support the motorcycle on its centerstand on
a firm, level surface.
Remove the oil level check cap from the final
reduction gear box. Check the oil level. It
should be flush with the lower edge of the oil
filler hole. If the level is low, add the
recommended oil until it reaches the lower
edge of the opening.
Recommended oil: Pro Honda Shaft
Drive Oil or equivalent Hypoid gear
oil (SAE 80).
Install and torque the oil check cap.
Torque: 19 N·m (2.0 kgf·m, 14 lbf·ft)
18. Clean the brake discs and
the motorcycle.
Clean the anti-rust coating off all three brake
discs with Pro Honda Brake Cleaner or
equivalent and a clean shop towel.
19. Initialize the ECM.
The GL 1800 uses an electronically controlled
IAC (Intake Air Control Valve) to minimize
idle fluctuations normally caused by air
temperature and load variations.
Idle Speed: 700
In order for the IAC to operate properly,
the ECM (Engine Control Module) must
be initialized.
Start the engine and let it warm up to normal
operating temperature.
Once normal temperature is achieved, allow
the engine to idle, without touching the
throttle, for at least 90 seconds. If the throttle
is operated during this time, the ECU will not
initialize properly and the process will need to
be repeated. Idle speed should stabilize at
±
700 50 rpm.
