Just a thought, my clutch fork has two holes/dents in it to attach the slave rod to.

Did you use the inside one or the outside one. If you use the outside hole, you won't have enough travel to fully disengage the clutch. Put it in the depression/hole nearest to the transmission.

A 7/8 MC will only move a 7/8 slave rod one inch, so yours is moving just about right. The only other culprit could be that the replacement clutch fork could be just a bit longer than your original one. Thus requiring a bit longer slave throw. The way to get that is to replace the master cylinder with either a 15/16ths or 1 inch master cyl. The one inch M/C will give you about a 1.34 inch slave rod travel with your current slave cylinder. An increase of .34 inches in travel. If you can, measure the length of the clutch fork and compare to your original.
