which master Cyl. is "stock" on 1985 xj700 Maxim?

I've owned the above cycle for 10 years but it had only one side of the front brake that was connected. I decided to get both sides working, so bought a longer bolt, with 2 holes, to connect both brake lines together, but when I went to bleed it and get pressure on hand brake, it would not do it--1/2 a quart of fluid. So I figured I needed a master cyl. rebuild kit, so ordered one off ebay. Nothing on that kit fit my plunger that goes inside the master, and I contacted the supplier and they ask me if my master is "stock"--I suppose meaning did it come with the original bike, for they say they sent the right kit. I bought this bike used, so I don't know. So I'm asking you guys who have original "stock" if you can look under the master and tell me what it says--on mine, it says "nissin 6h5". I live 100 miles from Phoenix so it is hard for me to go a junkyard there to find this out. Thank you.

 

longer bolt to connect the two hoses. nope
here is your brake system parts list as well.
your brale line should connect to the side of the mc

 

the dual disc brakes are a hard thing to bleed many threads on it.

here is a full setup on sleaze bay you can look at to compare yours to
1985 Yamaha Xj 700 N Maxim Front Brake Set Up Calipers Master Cylinder Makeoffer

 

XJ650 non-North American (dual disc) models, XJ650RJ Seca, all XJ700, XJ750-X, XJ750RL, and XJ900RK and RL models: the cylinder body will have the word NISSIN cast into it along the larger rear facing side of the cylinder body, and have the size 5/8 cast into the forward face of the cylinder body just to the left of the fluid outlet port (where the brake line attaches).

The 6h5 number is probably a manufacturing date code, not a part number, and does not help in identifying your master cylinder.

If you could post a picture that would be most helpful.

It looks just like the one on my 85 XJ700N. Got my parts from Chacal and everything fit perfectly.
