First ride on my RC - Clutch goes bad

Finally I got my RC finished and a break in the weather so I can get it to the dealer for it’s out of province inspection. I’ve spent the winter servicing the bike (filters, plugs, tires, pads, and all fluids) which included fixing a leaky clutch slave. I cleaned out all the crap gave the cylinder a rub down with fine grit paper replaced the seals and it worked great, although like others the clutch bites right at the end of the lever.

It’s a 30km ride to my dealer and my RC performs well and gives me a chance to get used to its character, it sure is different to every other bike I’ve owned and will take some getting used to.

So I check the bike in with the service manager and he gets on my bike to ride it over to the workshop. Of course he cannot get it started, so I explain were the choke is and it fires right up, then he cannot get it moving, what the heck! I give it a try, and the clutch won’t engage, WT…

The lever felt normal, there’s no hydraulic fluid leaks that I can see

Disappointed, I had no choice but to leave my bike with the dealer for the inspection and to fix the clutch, driving home I’m thinking the clutch slave piston must have stuck.

I’m hoping once the bike sits overnight maybe it will release and if it doesn’t have encouraged the shop to try tapping the cylinder to see if it that will release it, I just hate the thought of them ripping into it and telling me about all the parts that need replacing.

So the clutch would not disengage?

As an aside, my old 2000 VFR800 had a similar situation where the slave cylinder was leaking out the bypass hole at the bottom.
Rather than take a chance on replacing seals with a possible worn cylinder, I just replaced the whole slave cylinder assembly.
The whole process was fairly painless and quick. Even the bleeding went easier than I expected.

The opposite, the clutch won't engage, it's stuck disengaged.

I agree a new cylinder is likely the best fix, how much of the assemble did you replace with new beside the cylinder? Mine was also weeping from the hole at the bottom of the cylinder.

It came as an assembly, ready to go.
All I had to was unbolt the old slave cylinder assembly, and set aside, then clean the old gasket material off.
Then install new gasket, then bolt the new assembly in place and torque, followed by bleeding.
Cleaning off the old gasket material took the longest time.
The slave cylinder assembly wasn't cheap, but I was trying to get the bike running as quick as possible.

Still waiting on the dealer to tell me what went wrong but I'm thinking if it is a stuck slave piston wouldn't the lever have a different feel, like more resistance?

I had the same problem, I thought I have a burned clutch, it turns out it was a $20 dollars kickstand switch.

Got my RC back from the dealer this weekend, clutch problem was a bit of crap blocking a port in the master cylinder, it also needed steering head bearings to pass the test. Any way had my first proper ride yesterday, just 100 miles but what fun love the engine and pointy handing so much more character than my other bikes.

It is awkward to start when warm,I'm finding it easiest to use the choke, not so easy when stalled at the light, any other tips out there, yeh I know don't stall it dummy

Congrats on the clutch issue being an easy fix. Some tips about riding these i found helpful are as follows...
1 Change the gearing -1tooth front +1 rear. This helps get the ol gal moving with less throttle. 15/41
2 Crack the throttle a little when warm starting, this helps mine start easier and the little blip of twin exhaust always gets attention

soft rev, flapper, 15/41
