1974 XS/TX650 rebuild

Nothing against Chinese here, they make some exceptional stuff, my stator and rotor are made in China. Most of the stuff you buy in your local, thinking its locally made, is made in China, it just has the locals sticker on it. People are so easilly fooled, very difficult to avoid Chinese made.

But, I may not get to use the slave. After looking around for master cylinders, I couldn't find matching clutch/brake masters of the size I'll need (12/17mm), so it'll be either non matching masters, or, an easy pull for the stock cable

I use Chinese stators in my bikes, at one tenth the cost of 'factory' Honda, and a three times that for 'factory' BMW, it's a no brainer, and just like the factory stators full vacuum impregnation with good epoxy to stop magnetically induced 'fretting' rubbing through the insulation is worthwhile, still looking for a pump to do that.

I agree about chinese stuff, it is almost impossible not to buy it. My comment was not against their stuff but just an acknowledgement that some people are not happy buying from Aliexpress.

For Xmas I was given a chinese tilting table and a chinese rotary table. The tilting table was crap, over 1 mm out of level over the length of the table and there was considerable rock when it was put on a surface plate. The base and top had mismatched radii and most surfaces looked like they had been "machined" on a linisher not a grinder nor mill. The castings were very good though and after machining the whole thing I have a nice table. On the other hand the rotab came with a calibration certificate which I confirmed and was machined to a high standard and had no need of improvement. It is hard to tell in advance what the quality will be on any particular item.

About the master cylinders. It is not difficult to sleeve them down, just a question of finding suitable seals in the diameter required. If you sleeve then it is beneficial to use a ball hone as the final finishing on the bore. Around 2009 I was gainfully employed (an unusual occurrence, because I have mainly been self employed) and I designed an unusual braking system which required custom cylinders. I had these on test for many days with thousands of applications per day. Tests were done with different bore finishes, those that had been done with a ball hone were always better.
