Gas Gas clutch

Hi All

I have a 2012 Gas Gas 250 Tx Pro with on going clutch problems, I replaced the master cyclinder from Rock Garden exactly 12 months ago and the bike rode well until recently, when it started to jump forward when I put it in gear and now the clutch does not work at all. I purchased a new master cyclinder and bleed assembly from Ktm on Saturday, because I noticed the year old master was leaking oil when you pulled the clutch in. I tried to bleed the system on Saturday, but had no luck. I checked you tube and what I can work out is it is probably the slave cylinder, which may have been the problem all along. Can someone please help me with the way forward or is there someone that can fix this for me.
