NOTE
Check the level when the engine is cold (room or ambient temperature).

Check the coolant level in the reserve tank [A] with the motorcycle held perpendicular (Do not use the sidestand).
If the coolant level is lower than the “L” level line [B], remove the upper fairing assembly (see Upper Fairing Assembly Removal in the Frame chapter), and then unscrew the reserve tank cap and add coolant to the “F” level line [C].
“L”: Low
“F”: Full
NOTICE
For refilling, add the specified mixture of coolant and soft water. Adding water alone dilutes the coolant and degrades its anticorrosion properties.
The diluted coolant can attack the aluminum engine parts. In an emergency, soft water alone can be added. But the diluted coolant must be returned to the correct mixture ratio within a few days.
If coolant must be added often or the reservoir tank has run completely dry, there is probably leakage in the cooling system. Check the system for leaks.
Coolant ruins painted surfaces. Immediately wash away any coolant that spills on the frame, engine, wheels or other painted parts.

NOTICE
Never drop the ECU especially on a hard surface.
Such a shock to the ECU can damage it.
Lift up the front portion of the fuel tank, and hold it with a
suitable bar or block (see Fuel Tank Removal in the Fuel

Brake Line Bleeding
The brake fluid has a very low compression coefficient so
that almost all the movement of the brake lever or pedal
is transmitted directly to the caliper for braking action. Air,
however, is easily compressed. When air enters the brake
lines, brake lever or pedal movement will be partially used
