No luck so far finding a Nissin MC for $20 or less.

This looks too good to be true. Thinking it's a knockoff... Half inch is about 12.5 mm which should be good.

Yeah knock off or backdoor sales from the Chinese plant that makes them for Nissin.....

So it might be OK????
????????????
You pay's your money and takes your chances.
I've successfully used chinese MC's
1/2" is actually 12.7mm. I have one on one of my 650s. It will give a bit better "feel" and modulation compared to the stock 14mm unit, but not as big of an improvement as an 11mm. I also don't think the mirror mount is reverse thread like the original Yamaha one. That's the nice thing about using one from another Yamaha - you get the reverse thread mirror mount, your brake light switch swaps in, and the lever swaps.

It's only about $20 and not seeing much else that'd work...

Yeah, the brake light switch looks funky but I should be able to make it work. My stock mirror broke off & left a piece in the threads so I'd have to drill it out & get another mirror anyway. This MC comes with a lever. I think I might try it.

So the Nissin MC arrived and the 1 pc. brake line. Had some trouble connecting the line because the ends were not in the right position. I had to twist the line 180 degrees to get it connected but I was able to do that. It wasn't too hard to get the new MC pumping fluid and I filled the caliper with fluid before connecting the line. From there it was just a matter of doing a little pumping and bleeding. Front brake works fine now.
Not sure but maybe I forgot to prime the old MC before hooking it up. Maybe that's why it didn't work. Or maybe it was just screwed.

I have found that the knock off MC's are not cleaned before assembly. After a while you may find the fluid becomes dirty. I have had good luck so with them far fingers crossed.

I might have cleaned it if I'd seen your post before putting it together but now I guess I'll wait & see what happens. What can I expect to happen if there is dirt in there?
Seriously. Dirt in a master cylinder can cause brake failure. Best to be sure.
I'm surprised you had to put a twist in the brake line. All the cheap lines I've gotten from eBay came with the ends in the same plane, parallel to one another. That works well for a MC like yours with the front mounted line. You do need to put a twist in it if you try to install it on a stock MC where the line connects on the end. A line with the fittings at 90° to one another works well for that. But, it would be nice if you've stumbled across a seller that has them with ends at 90° to one another. Like I said, all the ones I've gotten so far have parallel ends. Got a link?
Regarding the new uncleaned MC's the only thing I have noticed was the fluid discolours very quickly but that grime can be doing the system any favours.

So can I just flush it out or is it necessary to disassemble & clean the MC?
So, have you got a link to where you got the line?
Some brake lines are "adjustable", the banjo is connected to a sort of "pipe union" that in turn is swaged to the hose. Venhill in the UK have hoses with that feature.

Well, it was late & I was pretty tired so maybe I just couldn't figure it out. I'll take another look & post the result.
I tried flushing but in the end had to strip and clean with methylated spirits which I think is called denatured alcohol over in the states.

I don't see any discoloration and I don't feel anything strange when I pull the lever. I think I'm just going to go with it as is & be aware of any changes. I'm not going to be trying to set any land speed records.
One thing that's disappointing is there's no adjustment at the lever on this MC. I wouldn't have bought it if I'd realized that.
