Fuel
In the condition at delivery, the LC8 engine requires unleaded fuel with at least RON 95
(USA = Premium PON 91).
If using lower octane fuel, it is easy to change over to the pre-programmed ignition curve for
80 - 94 octane (RON) (see activating the ignition curve for low-octane fuel).
After refueling, it will take approx. 8 minutes for the fuel warning lamp to switch off and for
TRIP F to automatically reset to 0 and return to the previous display mode.
NOTE:
Press the SET key for 2 seconds to immediately turn off the fuel warning lamp.
– Use unleaded fuel with at least RON 95 (USA = Premium RON 91). If using lower octane
fuel, the ignition curve must be changed, otherwise engine damage will occur.
– This motorcycle is equipped with 2 catalytic converters. Leaded fuel will destroy the cat-
alytic converters. Please use unleaded fuel only.
The 990 Adventure has 2 tanks with 1 filler cap each. Both filler caps can be locked and
are equipped with a tank vent system. To open, insert the ignition key, turn 45° in a clock-
wise direction and fold up the filler cap. The ignition key can be pulled out to open the other
filler cap. Simply press on the filler cap to close.
Fill the right tank first, then the left tank (see drawing for the maximum filling level). If the
right tank is filled up to the filler neck, fuel may overflow when the motorcycle is parked on
the side stand after refueling when the fuel becomes warm.
Gasoline is highly flammable and poisonous. Extreme caution should be used when han-
dling gasoline. Do not refuel the motorcycle near open flames or burning cigarettes. Always
switch off the engine before refuelling. Be careful not to spill gasoline on the engine or exhaust
pipe while the engine is hot. Wipe up spills promptly. If gasoline is swallowed or splashed
in the eyes, seek a doctor’s advice immediately.
