Any drawbacks to vented clutch cover?

I have seen that many people run vented clutch covers on their Ducati's. I understand the benefits to be allowing heat and dust to escape from the clutch?

Is there a downside to doing this, i.e. water or contaminates entering the clutch?

I've been thinking of doing the "remove the gasket" cheapie mod instead of spending the dollars on a vented cover.

No personal expirience, but I've read on the subject some (I was in the market for a monster). There dont seem to be any real benefits to a vented cover, it seems more of a looks thing than anything else. Downsides are mainly that clutches start to rust, but my understanding is that the problem increases as frequency of use decreases. That is to say, if you ride your bike on a regular basis, dont worry about it.
The other downside is increased noise from the clutch. Have you heard what an exposed clutch sounds like?

I have heard them before, they are a bit loud. Supposedly it adds to the "Ducati character."

My gut reaction has always been that it didn't seem like a good idea, but then every Ducati accessory outfit sells them.

I thought maybe it made more sense on a track bike, versus a mostly street ridden one. My main concern would be water and road grime getting in there, as I do ride in the rain every now and then.

If you like the sounds of ball bearings, metal shavings, and glass in the engine (Thats what I thought of when I first heard it) then go right ahead.
Water will rust the plates a tad, but the rust will dissapear with application. The danger is having your plate rust together if you leave your bike unused for a few years.
As for road grime, a clutch is basicly no different than a brake, and your brakes are exposed to the elements right?

Just dont bother looking for any performance.. Its a looks only mod...

It does alot for keeping the clutches cooler, i have seen many people drill there covers full of holes, and they had no problems at all.

As far as water, well if you ride in the rain alot, then maybe research this further, but so many people do it, i do not think its an issue.

I may not know everything about somethings, but i know something about everything!

LOUD CLUTCHES SAVE LIVES!!!

Anything that goes in usually just gets flung out. I actually have to wipe clutch dust off my boots and tail section after a long ride. I think Vash is right about the rusting together part but sofar I've never had a problem.

Stock Ducati clutches are pretty loud even louder when they get worn out a little. When you use a vented cover it can sound like the bike is falling apart. The sound really bothers some people and cage drivers don't know what to think. I put a STM slipper on recently, and it's a lot quieter, but it still has the ching ching ching sound. The basket is made out of aluminum which doesn't seem to ring quite as loud as the steel one did.

Edit: Also the clutch housing is tucked in behind the fairing so not much water gets in anyway.

A few ccs short of a full litre.

Thanks to all for your input.

I think I'll try running the stock cover without the gasket and see if I can deal with the noise, and see how much dust comes out. I'm not too crazy about additional dust that I'm going to have to clean off.

If I don't like it I'll just put the gasket back on.

We used to get a lot of Ducati owners coming into the shop with a "strange clutch noise." Almost always it was a case of them not knowing what a dry clutch is. I've lost count of the number of times I've explained the dry clutch setup.

I love the sound of the dry clutch and anytime I hear a Ducati sitting at a light it's like hearing an angel sing. It's second only to the sound of a Ducati at full throttle blasting past at 150mph!

Musically:
Ching, ching, ching goes my ducky. Ring, ring, ring goes my clutch.
Etc.

Sorry!
