Ok the master cylinder the most use is off the fjr1300 and some have used the R1
they are a 14mm
so is the smaller piston (14mm) used cause it is easier to pull/move the brake caliper but provide more force
so trying to find a fjr1300 m/c is a pain ( i want the mirror mount)
so i looked at a guys honda shadow at work today and they have a 1/2" m/c piston would it work or be to much
ya i know 1" handlebars
