Where did my GL1500 brake fluid go?

imported post

Hadn't ridden in a little over a month due to bad weather and other assorted excuses. Well, Saturday I sensed it was time. It was a little overcast but I said what the heck and dressed in my finest riding attire. Jumped on the Wing and grabbed the clutch handle in preparation for rocking her off the center stand and.... no clutch at all.

I jumped off and opened the reservoir. It was bone dry. I looked under the bike, no trace of a leak either on the garage floor or the bottom of the bike. I opened my service manual and read up on how to change the fluid. After flushing the system with clean new brake fluid, I once again had a clutch. I then took her for a 60 mile ride. The clutch functioned perfectly without any hint of a problem. when I got back, the fluid level was unchanged.

I've owned her for about 2.5 years and have never checked the clutch fluid and never had a clutch problem. Last time I rode, a little over a month ago, I covered over 300 miles and had no hint of a problem.

The fluid obviously didn't leak out while it was sitting in the garage and, to my knowledge, it doesn't just evaporate. So where did it go? and more importantly, will it go there again? Should I carry a bottle of brake fluid in my saddlebag for emergencies?

btw: I just checked it again and the level is unchanged and there is no fluid on the garage floor.
