Let's see those rear master cylinder setups!

Once again the previous owner strikes again. I no longer have a stock MC on my bike and I have a bel-crank "racing" master cylinder installed on a welded on bracket to my frame. It looks terrible and I'd really like to clean this up and keep the rear triangle tidy for my cafe setup.

Let's see what you guys are rocking for your rear master cylinder setups. I've tried to source a used stock one, but that seems to be a tough task.

Repair kits are unavailable for the stock rear master cylinders so going with a used one is probably a headache waiting to happen.
