Can clutch fluid leak into the engine oil with the bike not running?

This boy is perplexed.

I dont think so. The clutch uses the engine oil and the clutch fluid just operates the plunger to engauge and disengauge the clutch.  How do you know you have clutch fluid or brake fluid in your oil?

Bonzo:

If I recall correctly, the clutch fluid can mix with the engine oil.  If your clutch fluid is disappearing, this may be your situation.  Look at the parts fiche for the clutch cover and slave piston, you will notice a notch at the 6 o'clock position in the center of the cover.  This allows any bypass clutch fluid to drain.  It's been awhile, but this is where the clutch fluid will enter the crankcase.

If someone else can confirm this one way or the other, I would appreciate it.

I went to start the bike up after about a month and the clutch master cylinder was just about empty. I cannot find a leak.  I am going to give it another good looking over this weekend if it gets above 20 when I am home LOL.   Thanks

The leak is happening at your slave cylinder. If the piston seal is cracked, you can have fluid leaking into your crankcase. Get a slave cylinder rebuilt kit, then rebuild and bleed.
