Disappearing clutch fluid.
 

...

Probably at the slave cylinder

Into the engine oil? Is that level rising?

there's gotta be a seal somewhere... Damn, I just read the above.... I hope that isn't it :eek:

that would be my guess. the older aprilias had that problem with a seal letting go. Got an aftermarket slave cylinder and all was good.

No idea, but hopefully it is nothing serious.

it IS serious if fluid is disappearing. I'm going with slave cylinder leak.

I've never delt much with hydro clutches. So I have no personal expierence to back up on. Sorry.

Where is the slave cylinder? Outside or inside the engine case? I've never really looked since I don't own anything with a hydraulic clutch.

Yes, but I meant serious as in below.

brake fluid is a serious problem, ESPECIALLY if its getting into the oil. shits just like having water or any non oil substance in there.

usually you can find the slave cylinder somewhere on the left side, most likely someplace near the sprocket cover, or ON the sprocket cover. I wouldnt be surprised AT ALL to find a huge accumulation of extra filth and grime on the area around the slave.
