I run open belt covers on my 1100 EVO motor, its got a lot of noise coming from the pulleys like the bearings are not lubed. the motor has about 3000 miles on it if that. The clutch (wet) is also pretty freaking loud for a bike with a wet clutch. I read that this is common though. It isnt the quietest wet clutch out there.
Is there a common issue among these motors that i dont know about?
How much time is involved in pulling the cam out and inspect it/replace it?
Does it use the same pulley configuration and tension specs as the 1000 DS?
If so the pulleys will get noisy if the belts are set to spec. Loosen them a few hz.
It is the same configuration, but im not sure of the tension spec. Ive been using the 5mm key method on both motors.
To clarify, is the actual cam pulley bearing is inside the head? the noise might be coming from the tensioners themselves, but when i unload the belts, they roll without resistance.
Ill try to reduce the tensioner to a 5.5key and see if the noise changes.
With smart phones these days, i might just try to actually tension it to the spec...gotta find a manual though.
I've run open belts on my 2012 1100evo for about 14,000 miles and have never experienced belt roller noise.
I am not aware of a "common issue among these motors" related to either the belts, rollers, or clutch.
There is a wealth of knowledge available in this forum regarding belt tensioning. The evo motor adjustment is basically the same. The main difference is the timing mark location. Since you say there is a lot of roller noise, your best bet is to take that as a warning and do something about it.
The clutch should not be excessively noisy.
Have you compared the clutch noise to other evo's?
I don't see a need to remove the cam for inspection until you have adjusted the belts. As for a time estimate, you need to be more specific. Do you mean time over and above adjusting the belts, or over and above a valve adjustment, or time from scratch? Supposing that someone estimates those times, what will do do with that information?
Re the cam bearing, take a look at any of the online parts fisches and you will see that there is no separate cam bearing for the evo. The cam journals ride in the cylinder head bores.
Wot DP said. :)
I'm pretty sure the cams ride right in the aluminum of the head on the DS 1000 and the Evo motors. Noise from that would be a serious issue.
If you're using the Allen key method the belts are already looser than spec, which is 110 hz for a new belt and 100 hz for a used belt. Chris at CCW says to reduce the tension to 100hz for a new belt for his exact fit belts.
in that case then the noise wouldn't related to too much tension on the belts.

- I am working to resolve the issue now. I have not compared the noise to another wet clutch ducati motor since I don't know of any around me.
I cannot pin point the exact area of the noise since the whole bike is pretty dang loud at idle. Its something i hear with earplugs in while riding and above the motor (I have TPO Beast-R intake, its freaking loud if i get below my tank).
The point of asking for the time was to determine how much time i should allot to the task, my car shit its clutch over the weekend and my other daily commuter bike was stolen in December. without my duc, i have no ride, so i need to prepare accordingly.
If the journals ride in the cylinder head, then it should have its own oil supply, i dont see why they would fail otherwise with such low mileage. im going to try a bit harder to locate the sound and get back to you guys. It might just be the tensioner. Theres surface rust that i blast off all the time. Just part of living on the east coast and having the bike outside.
I don't think it has anything to do with the surface rust.
I'm betting a bad bearing in a roller or tensioner that slipped by you on the last belt change.

Surface rust where that you're blasting off with what?
A way to locate the source of the noise is to use a tube, one end in your ear and the other at the places that you suspect. Or you could use a stethoscope if you can find one.

Or a long screwdriver. You will hear more noise with open covers. Wet clutches should make noise, enough to hear a difference between engaged or released in neutral, not much more.
while checking the electricals on the bike, i ended up inspecting the belt tensioners.
They are all squeaky. But you cant hear them very well when the bike is on. I took off the tensioner the rust off on my polishing wheel and ended up realizing that i could use the polishing wheel to spin the bearings up. In doing so, it was evident that they are on their way out.
Anyone know if they are rebuildable? Ducati OEM shows $52 each assembly x 4 assemblies!
Mcmaster carr might have a suitable replacement
