ok so maybe i should be looking for the 1 1/8" bore first and see how i like it? do you think the 1.250 would be to hard even with the dual 7" or dual 8" booster and stock/high vacuum? (14-20)
The larger the bore the more fluid it moves per given stroke, and consequently the less pressure it produces. Smaller bore M/C's have more pedal travel but pressurize the brakes harder to give better pedal feel.
