The bore on my master is 1-inch. My pedal doesn't travel halfway through its stroke before it becomes solid. You probably need to play with the pedal ratio.
I have my master mounted on the crossmember and fabricated the linkage to pull on the master cylinder. This design allowed me to control the amount the pedal traveled vs. bore stroke in the master by adjusting the pivot points and thereby changing the pedal ratio similar to a hanging pedal setup.
