Hydraulic clutch install woes

I'm working on getting a hydraulic clutch setup on my 78 KZ1000. I was switching the bars anyway so figured this would be a good time. I'm having some issues though.

I'm using a slave cylinder from a 92 ZX-7. I was able to grind the case cover and mount the slave so it lines up properly with the clutch rod. I cut approximately 7/8" from the rod. The slave cylinder was making contact with the rod but didn't seem to have a long enough stroke length to engage the clutch. I replaced the seal and spring on the slave with no change. I was using this master cylinder. smile.amazon.com/gp/product/B01F0DZMOA/r...07_s00?ie=UTF8&psc=1 With this master cylinder the lever was firm but seemed to lack stroke length.
I thought that maybe the master cylinder didn't have a properly sized piston so I replaced the master cylinder with one from a 96 ZX-7 thinking that it would be a better match. The stroke seems to be even less now and I can't get the lever to be firm with bleeding.

I am using a mityvac brake bleeding kit to bleed the line. I am using new lines from spiegler.

Does anyone know the proper stroke I should be getting in order to engage the clutch. Any ideas? Thanks

Aha! Im also trying to set up a hydraulic conversion on mine. Ive been at it for some time now. Im using a matching master and slave from a 95 ZX9R (so I know the ratios are good) and I havent cut the push rod. Instead I made a mounting plate (I ditched the side case) and have been using spacers to move the plate (plus the piston) further out or closer in. I have been at both extremes and moving bit by bit tried to find the sweet spot. Still havnt managed it. I upgraded to better quality oil a couple of weeks ago,which hasnt helped much. Last weekend I pulled the clutch apart to check the plates.In th process,I broke a coupkle of spring mounts on the inner basket!!!!! Ive ordered new springs and plates and Im looking for a new inner basket.
The saga continues.....!

On the other hand,there are people here who have done the conversion with no problems and are happy with it. Good luck with yours.
