Had the same problems after I changed the clutch on mine. If you follow the procedure described below, you might have a good chance of bleeding the system.
1)Make sure your fluid reservoir is totally topped up. This is due to the clutch system has a higher situated drain inside the reservoir to avoid brake failure due to a leaking clutch cylinder.
2) Mount a 2meter clear hose on the clutch cylinder bleed nipple, and hold the other end of the hose as high a it reaches (perhaps under a wiper and along the windscreen)
3) Loosen the bleed nipple
4) Now slowly pump the clutch and the trapped air is visable in the hose. Pump till the fluid reach the high end of the hose
5) Release the clutch pedal and move your foot from the pedal. Slowly the fluid inside the hose starts to run backwards in the system and into the reservoir again.
6) Thighten the bleed nipple and hopefully the clutch pedal acts normal again.
Hope this makes a little sense, It surely sounds a bit crazy
Good luck
