I have a 80 inch evo 5 speed in a hartail frame, I'm running a PM caliper, I put the caliper on a year ago because it always just felt like my bike was slowing down not stopping I emailed PM and they told me to run a 5/8 bore master cylinder I finally got a MC which is a jay brake and after a lot of problems I got it on and bled I take it down the road and same problem i'm running dot 5 any sugestions
