George, your question belongs in the Post 1970 Airheads forum. The topic has been moved to that forum.

Welcome. I stayed in schlump for a week, a long time ago. Very nice nurse! As far as your master goes: if there is no corrosion or any damage, just rebuild it with the OEM kit. It's an easy job. The only reason to change the diameter of the master is if you want a stronger feel at the lever. You would then reduce the diameter to give more mechanical advantage. If the brake feels good the way it is, there is no reason to change. Replacing brake lines from rubber to braided steel lines can do a lot to improve braking response.

• I recommend disassembly of the m/c first so you can see what you have. If there is deep scoring, or rust pits, then it will need replacement.

• The sizing on the R65 m/c bore is about right.

• If you want the bike to really stop, then do these things...
- Replace the OEM rubber brake lines with steel braided lines (generally called "stainless steel lines"), like Spiegler https://spieglerusa.com/
- Replace the old hard brake pucks in the front caliper
- Clean the caliper out very good
- Install clean fresh brake fluid, and be sure and get ALL the air out

• If you REALLY want the bike to stop, then install one of those EBC floating brake discs

You won't need more brakes that those changes will give you.

Need Shmeed. WE ALWAYS WANT MORE BRAKE!

Brakes are overrated. Especially when there's a sports bike to dispatch.

Welcome George. I rode an R65 for about 15 years. Good machine.
