Clutch failure and FAIL on the screen

Hey friends

On the yesterdays ride, at the end of the route(only 10 miles left, thanks god) my clutch failed, I pulled the clutch lever and it was soft, no pressure, and the gears did not disengage, if I had to brake, the engine stopped. I felt that smell if burnt clutch sometimes, not too much. And then the screen showed the FAIL word.

I took the bike home and today I went to move it from one side of the garage to another without starting it and the clutch lever was firm, I felt it like nothing happened.

My chances are, clutch needs replacement, oil was too hot and made it fail, or clutch springs damaged, what Im scared about is the FAIL on the screen. Is this directly related? is there any sensor on the clutch that could make it appear?

Thanks for your inputs in advance

I don't think the FAIL readout had anything to do with the clutch.

I'm thinking the slave cylinder might be bad.

Look for leaks
Change your clutch fluid
Take clutch apart and see if it is burnt.

OKay, yesterday night, I started the bike, took out for a short ride around the neighborhood, and the clutch was perfect, as if nothing had happened.

Im still freaked out about the FAIL more than about the clutch.. what do you think about it? Is there any way to know where the FAIL message comes from?

This is the oil that was inside the engine when it all happened. Ma ybe it was the cause not sure...

is this an energy saving oil, I can't tell from the web site, but if it has friction modifiers that could be the clutch issue.

Yup

That oil is NG.

But......that would cause the clutch to slip.....not lock up like it did.

What does NG mean? I have to add that the ride was extremely hard, we begun at 9am and ended at 5 30pm, and there were river crossings, muddy as hell, hyper technical trails, super slow speeds, almost just using 1st and 2nd gears, high revving, and continual stop/start the engine. Does this affect?

Yeah, I will use this one from now on and see what happens

Check the clutch fluid level.

Your engine oil didn't cause the failure. I've seen endless clutch issues resulting from 50W oil in the x-lites and 449s, however, many have used it successfully for thousands of miles. I would change out your hydraulic clutch fluid/bleed to 5.1 if available. Motul 300V 5W40 is good, hope it's not too expensive.

Thanks Tinken, do you know if the FAIL message can show up because something is failing on the engine? Such as valves, timing chain, etc? Im afraid about it.. About the oil, it costs 35 USD the bottle.

Thanks friend! you are welcome to come here and have some fun! And yes, I have to check all you mentioned, sometimes it requires time and I dont do that often, but I will, promise..

Fail message is from something electrical like a sensor or break in connection.

I don't think your clutch has failed. I think the fluid got low and bouncing around or bike on it's side got an air bubble in the line. So it was spongy when you squeezed it and did not move the slave piston enough to disengage clutch. That air bubble has worked it's way out now and clutch is fine.

Is bike still saying Fail? If not forget about it. Electical glitch that went away when turned off and on.

Yes, it is a possibility indeed, because later on, after the ride home(bike on the truck) it worked fine. However, I suspect more about the oil..

The FAIL error, appeared randomly twice during the last part of the ride, when I turned ignition off and back on, it dissapeared. Few minutes later showed up again, and the same happened. When I rode the bike around the neighborhood to check the clutch it didnt showed up. So as you and Tinken said, it is electric glitch

I didn't say it was a glitch, I said it was electrical. I'd go through all your connectors with dielectric grease and see if that solves the issue.
