Ok, your initial reaction is - from the plates hitting the clutch basket dummy! Well yes, when you pull in the clutch lever you get some higher frequency but lower noise level from there BUT I'm talking about when in neutral with the clutch lever left alone and the engine ticking over. Under these circumstances there is a different and heavier clanking noise which to many people (and a proportion of Ducatisti as well) is bordering on objectionable. If you stop your engine and rotate the clutch back and forth by hand you will hear the knocking noise coming from inside the engine casing and no way when doing this by hand are the clutch plates hitting the clutch basket since they are all clamped together by the springs. I've checked this on a couple of dry clutch Ducatis and the result is the same. So, if the main tick over clanking noise, which goes away when the clutch lever is pulled in, is inside the engine casing is it the primary gears rattling against each other and no amount of dosh spent on new plates/basket will get rid of this noise? Maybe, once these dry clutches have some miles on them the 2 bearings holding the larger of the primary gears and the clutch basket behind the clutch basket wears and increases the tooth/tooth clearance between the gears and this causes increased clanking noises? Or, is it gear/gear clearance clanking in the gearbox which goes away when the clutch lever is pulled in with the engine running by reducing the engine pulses transmitted into the gear box? Can the clanking noise be reduced by changing the bearing behind the clutch? I don't have hands-on knowledge of the recent Ducati wet clutches or a workshop manual for them to see how their design/construction has been changed but they are quieter, but it can't just be the oil on the clutch because on dry clutches the noise comes from inside the casing behind the clutch. Anyone any thoughts on this? P.S. This is a technical topic and is not intended to start the 'love or hate the clutch noise debate'
