noisy clutches a problem?
Well, it depends on the noise. Ducati Monsters
come with two types of clutches: wet and dry. A wet clutch
simply means that the clutch is surrounded by motor oil; this
same type of clutch that's on a car and most other bikes. Wet
clutches are inherently quiet, so if yours is noisy then it
might be an indication of wear or other problem. Generally
bikes less than 800 cc (double check that 800) have wet clutches.
The remainder of this FAQ relates to dry clutches; wet ones
don't have dust to contend with.
cc and above bikes have dry clutches, so called because they
have no oil surrounding them. With these types of clutches
a certain amount of clatter at idle or with the clutch pulled
in is normal. If the clutch has an open clutch cover (you can
see the clutch plate spinning or the cover has spacers to leave
a gap) the sound can be quite loud, often causing 'helpful'
bystanders to tell you your bike needs service.
types of noise
In addition to the much-beloved Ducati dry clutch rattle, your
clutch may give off a low groaning sound when taking off from
a stop. Typically this means that the plates are slipping,
either from wear or dust. To remove the dust, simply open up
the clutch cover (the recessed screws don't need to be removed)
and blow the dust out. If that quick fix doesn't solve the
problem you can try opening up the clutch, removing the pressure
plate and de-glazing the clutch plates. While you're at it,
inspect the tabs that extend out to the basket and the basket
itself, for notching or signs of wear. A small amount of notching
is probably OK, but more than that means you probably need
a new clutch. Assuming everything is OK, be sure when you replace
the pressure plate that the notched threaded post matches up
to the hole in the plate with the arrow marking.
