Yes i did. With the 3/4" master, i had about 1/2" of fork travel (measured halfway down the fork arm, which is where i connected the slave to). I figured a shorter arm would increase the throw on the clutch side. We will see.
my slave is connected to the fork in the same place as the factory linkage was,,, i see a guy once in a while with a set up in a street rod,, he drilled a hole in the fork 1 inch away from the orignal linkage hole for his slave,,
you may need to make a pedal stop when you switch to the 7/8 bore so you dont over stroke the slave,,,
