Cleaning The Motorcycle - Ducati MONSTER 400 Owner's Manual

Important
If the gap needs adjusting, be very careful when
bending the side electrode. If gap is too wide or too
close, engine performance will be affected. This could
also cause difficult starting or irregular idling.
Clean the electrode and the insulating material accurately
using a small metal brush and check seal condition.
Clean the seat in the cylinder head. Be careful not to let
any foreign matters fall into the combustion chamber.
Refit spark plug into cylinder head. Snug it finger-tight
E
until it is fully seated into the head. Tighten the spark plug
at 20 Nm. If you do not have a torque wrench, you can
use the wrench supplied with the tool kit to tighten the
spark plug an additional 1/2 turn.
Important
Never use spark plugs with a heat rating other than
recommended or a thread length other than standard.
Spark plugs should be tightened firmly.

Cleaning the motorcycle

To preserve the finish of metal parts and paintwork, wash
and clean your motorcycle at regular intervals, anyway
according to the road conditions you ride in.
Use specific products only. Prefer biodegradable
products. Avoid aggressive detergents or solvents.
Important
Do not wash your motorcycle right after use. When
the motorcycle is still hot, water drops will evaporate
faster and spot hot surfaces.
Do not use high-pressure or hot water jets. Using water
cleaners could cause certain parts - such as front fork,
wheel hubs, electric system, front fork seals, air scoops
and exhaust silencers - to seize or malfunction and impair
the safety features of the motorcycle.
Clean off stubborn dirt or exceeding grease from engine
parts using a degreasing agent. Be sure to avoid contact
with drive parts (chain, sprockets, etc.)
Rinse with warm water and dry all surfaces with chamois
leather.
Warning
Braking performance may be impaired immediately
after washing the motorcycle.
Never grease or lubricate the brake discs. Loss of braking
and further accidents may occur. Clean the discs with an
oil-free solvent.
