Disappearing clutch fluid

Hi,

 

Where is the most likely culprit for clutch fluid loss?

 

Level through reservoir sight window noticeably down after several rides. Second time I've noticed this. Bike is stored inside and there's never been a drop under it. Does not seem visibly wet anywhere clutch-ish. I realize the volumes involved are very small.

 

Thanks

I would check out the slave cylinder at the end of the line.  I take it that you checked very closely around the master cylinder?  The clutch line is the only other thing to check.

 

 

Agree.

you only have master cylinder, line and slave cylinder in the circuit. Leaks at the master should be obvious. 

Line leaks, may be hidden by fairings, but you will probably see a leak.

The slave cylinder is down with the countershaft sprocket and chain.

A leak there will mix with chain lube and not be obvious.

I had the same symptoms this past spring. 2nd bird & have ridden these bikes for 10 yrs. Anyways, it WAS the slave cylinder seal as mentioned above. I ended up just buying a used slave cyl since I got a great deal ($25 !). I flushed the entire clutch system and it's been perfect.

Moral of story... change all fluids at least every other year (brakes & clutch fluid).
