Hello, I am new here and I am not a native speaker so maybe it will be difficult for me to explain my problem.. I've just bought ducati monster 620 ie 2003. As I know there is wet clutch. When I start it I hear a little noise from clutch. When I grab the clutch lever this noise stops. Is it normal wet clutch to be so noisy?? thanks a lot
I don't know how noisy your "noisy" is, but yes it's normally easy to hear it - even if you have loud exhaust. It's the same thing that happens on bikes with a dry clutch, but less loud because it's closed and covered in oil.
It's very unlikely, but IF the noise is "too loud" (ask another wet clutch Duc owner or a dealer) it CAN indicate that the clutch gears are worn. I wouldn't worry about it - especially since the noise changes with clutch lever pulled - which is to be expected.
here is vid of my clutch..

Yes, quite normal ;)
Is it working well?
How many miles?
What kind of oil and how often do you change it?
i've just bought it... it has 34000 km on tacho... i am going to oil change next week... i don't know what oil was used in it before.
Reasons I asked are:
If it's very old, the gaps between teeth on plates and their notches in basket CAN become large enough to cause rattle. Probably/maybe not on a 34K bike...
If the oil is old/bad it will make more noise.
If it doesn't function well, the plates might be worn/warped = more noise, but then you'd probably have functional issues.
My third clutch lasted 40K km with semisynthetic 15/50 (could go with 20/50) after the first two clutches both quit at 25K km with synthetic 10/40. This topic has many opinions. If your bike is parked outside in freezing temperatures - maybe 10/40 is better.
it is not parked outside in freezing temperatures. now it is around 15 °C and it is the temperature i start riding at. so you recommend semisynthetic 15/50?? i think there is even less noise with oil with higher viskosity..
Ducati recommends 10W/40 because of the plain bearing heads.
I'd stick with that.
If you can find a moto specific, or a non energy conserving oil (one with no friction modifiers) you'd be good to go.
I like synthetic moto specific because they seem to do better in transmissions.
Have you read our oil thread?
i 've started to read the oil thread but i got lost after a while...
Sorry for braking in your thread.
But I had similar problem on 696. I got new plates 20-50 Motul oil which i use for about 2k miles. And once on red light I heard loud noise that I never heard before. Just like at your video with difference that I have no noise at all at normal conditions. I turned off engine and gear seems to be stuck, and only after several attempts I've got it to neutral. What was it? Bad clutch pack installation?
Shift fork return spring? Just a guess.
i've just found this video... and as i was watching it, there was a noise vere similar to mine clutch..... watch this video at 06:00... this is probably the thing that makes the noise in my clutch... Ducatitech.com "How to" Wet Clutch Install (http://www.youtube.com/watch?v=WFv6YIK3WyY#)

No vid...
oh sorry.. i've just edited it..
Hmmm..
If the noise is close to that kind of obvious rattle, I think it's smart to open it up and check everything.
I'm going to change timing belt, oil a nd check everything next week.. thanks a lot for help
