Try this:
With your slave bled and ready, adjust the "slave to fork" rod until it just ( and I mean just ) touches between the pocket of the slave and the pocket of the fork.
Now, get your wife, honey or friend to press the clutch all the way to the stop ( yes, put in a stop ). Measure the travel five times and get the average.
If the average is around 3/8 of an inch, you should be okay ( just my opinion here ), if you are too short, you should look at volume versus pressure. In other words, for the amount of travel the pedal does, is enough volume displaced to move the slave 3/8 of an inch.
And, when you change the volume, the amount of pressure will change. If the pedal is very light, you may want to change the volume to increase the pedal feel.
Then you can adjust the pedal stop for length of travel so you get 3/8 of an inch.
Start out with the rod just touching.
BTW, try to make one end captive if you can.
Hope this helps.
