570 Clutch goes spongy when HOT

I am having a problem with the clutch on my 570 acting up when the engine gets hot. It's as if there is air in the system, the clutch lever will act like it has air in it progressively until the lever goes to the bars. Pump the lever 3 or 4 times and the clutch comes back...wait a couple of mins and there's no clutch again. It mostly does it when the engine gets hot......The thermo fan is running and there is no fluid loss. I have replaced the oil and bled the system a number of times with 15W mineral oil as recommended and I just fitted a slave cylinder kit and checked the bleed hole in the master cyl and it seems to be fine. I read on here, there were a few other guys having the same problem and there was no definitive answer so I am putting it out there in case someone has had similar problems and found how to fix it. Thanks

Had similar problems on my FE390, replaced the complete slave cylinder and now have a light, reliable and stable working clutch. Did some work on the old unit afterwards and will see if it is refurbisable as soon as this one fails. From what I read and heard these slave cylinders are prone to failure.

Thanks...I have pretty much eliminated it down to the slave cylinder but thought it better to ask before I buy

Did you fit a Berg slave or a KTM.......The latter is half the price and the seals and all the other parts are available. Going by the spares pics I see the KTM piston appears slightly different to the Berg. The gasket and O'ring is the same so I am 99.9% sure it's going to fit......Maybe someone who has done it or knows can let us know

Thanks

Did you push the oil from the slave and up with a syringe or such? If not theres likely the problem, its close to impossible doing it any other way without air being trapped. 2c.

Hey Tom, no I havenít so today I got a syringe and reverse bled it and didnít notice any air come up to the reservoir.

Seeing as I had the slave off I pulled it apart and found the sealing ring was quite out of shape so I fitted a new ring and bled it again with the syringe

Iíll see if that fixes it on the next ride 😊
Thanks from TomTom and tourist

I got a KTM one since they did not have Husaberg parts. Does the job just as good imho.
