Ktm65sx 2011 clutch problems

Hi all

My lads 65 clutch has stopped working altogether. Changed mineral oil .
Reverse blead it . But I've noticed tiny air bubbles in master after pulling leaver in .
Could the slave cylinder need new gaskets / seals ? Any help would be much appreciated 👍

Your description would indicate your master cylinder is leaking and pulling air into your fluid as the plunger moves. I suspect rebuild or replacement of master cylinder will correct problem.
Cheers for info il give that ago 👍
It was also doing it afterwards without pulling the leaver in ?
I get a few bubbles every so often.
My suggestion was made based on your observations and finding air bubbles in fluid. There would not normally be any reason for this air in master cylinder unless there were a leak in sealed system allowing it. If air was entering I would think the most likely entry point would be past seal on master cylinder piston. We would expect the air would rise through the fluid as you have observed. If the air were entering at a lower point in system I would expect you may find a fluid leak there. Hope that helps out. Good luck

Cheers once again. No leaks on it so I'm guessing seal on master cylinder 👍
