There are all sorts of choices for brake lines. CycleBrakes.com has Galfer lines w the fittings already crimped on. I got Goodridge lines & banjo fittings from Z1Enterprises.com. The diagrams at Partzilla for your motorcycle may have the lengths, but you can measure yours from eye-to-eye. If you plan on replacing the handlebars, do that first before getting new lines as the stock Ltd upper line will be too long for lower handlebars.
The stock master cylinder tends to leak at the cap, so if you plan on keeping it, you should clean it thoroughly. but it may still leak within a year afterwards. Remove all of the built up scale & crud on the cap & from the mating surface on the m/c. I used a wire wheel & awl >> some of the stuff was pretty hard. Install a new cap diaphragm.
You could install a Fr brake master cylinder from a modern or later model motorcycle. You would need one from a dual disk motorcycle with a 16mm mc piston bore. My motorcycle has a single disk Fr brake & I installed a good used m/c from a Honda CBR500 which also has a single disk Fr brake. piston bore for a single disk Fr is 12.5mm. Some m/cs
have a 14mm piston bore, but I'm not sure of their application.
