Three weeks ago, I sprained my ankle which sadly delayed my first ride of the year.

Prior to that, I checked over the bike, ran it, made sure the clutch and brakes worked, reset the clock and added a new top box.
I also planned on changing the oil & filter before the first ride but life had other plans.

Becoming slowly more mobile, I've graduated to no crutches and climbing up the stairs in under 15 minutes. Today, I was able to go outside to see if I could get myself on the beast, get the sidestand up & down, hold the bike up, roll it backwards and use the shifter. All went reasonably well until I tried to put it into first gear: the clutch snapped back with no resistance.

Needless to say my heart sank as I envisioned a massive repair bill from the local Honda dealer.

I opened the reservoir on the clutch and found it almost empty! It was also filthy as hell. I cleaned it out and topped it up with fresh fluid and then gave it a couple of squeezes: I got normal resistance. Some air bubbled up as I released the clutch so I squeezed slowly (while tapping the hydraulic line) until no more air came back. I know that's not proper procedure but bleeding the clutch was on the agenda after the oil change. It shifted fine after that so I just went back and forth a couple of times and shut her down. I also decided my ankle wasn't ready to ride.

A few hours later, I thought I would try some mounting therapy and noted the sight glass indicated half full.

Am I correct in diagnosing this as clutch slave cylinder failure?
Is a knuckle busting, cuss filled removal and rebuild in my future?

This is not something that I am looking forward to.

I've seen Max Pete's post on this and will be studying it at length.

Assuming that you have checked and there is no leak elsewhere in the system, yes.

Yes, yes, and no. The no is for the rebuild, just replace it with a new one.
