Thanks Leo, I have been looking at different sets. I just wasn't sure about what lines to buy with them or if they are pretty much all the same. You nailed it by the way, its a 75.Jafladd, There are many threads on Master Cylinders. Yours being a round one it is on a 72-76 bike. Right? If so it has a 16 mm bore. You might find a rebuild kit but they cost.
I might suggest shopping Ebay. Sellers on there sell a 14 mm bore M/C for around $30. I currently run one on my 75. They smaller bore M/c will improve the brake action and feel over that 166 mm one you have.
On lines braided stainless steel is the best.
You caliper is not hard to tear down to clean.
Threads on that to. A bit of searching will find them

The bike is great looking. Hopefully mine will look that good when I get it finished.High water on the Sylamore Creek in Stone Co. Arkansas has been keeping the XS land locked. Only able to toodle around in the yard.
Hope to meet a few of you at the XS Rallye in Mt. View, AR next month.
