I've managed to source some better rear master cylinder boots for the Chinese  master cylinders. The cylinders require a groove machining for the boots lip to seat in. I'm still looking for a source of nut and bolt hose clips of the correct size, alternatively you can fit jubilee clips. The push rod also  requires modifying which I can do for you or you can DIY. The cylinders come with a smaller reservoir and you'll need to get a piece of supply hose as the supplied hose will disintegrate after a short time. I have three with boots  done in stock should any K Kronies require a replacement.
Regards Martin.

I use a zip tie to hold the boot in place.  Works pretty well.  It's been a while since I have had to fuss with the master cylinder, but I seem to recall that I used the boot from the old master cylinder.  It worked well for me.

Gryph most of the time the OEM boot is toast hence the need for a replacement boot. We tried cable ties on Matts cylinder and they kept either popping the boot off or sliding off. Now with the machined groove it would probably stay on with nothing holding it on.
Regards Martin.

Hmmm...  I wonder why my boot never came off?  I need to go back and see what I did. 

Unfortunately, the first bike I did the swap on just left on a trailer for Texas last Wednesday.  Hope I still have the photos I took.

Firstle mine has been on since March 2017 without any problems and actually works better and has a better feel than the OEM one. For the price of $15.00 Au I'll be sticking with them. So far nobody has encountered any problems other than the reservoir hose being substandard.
Regards Martin.

+1  I have installed several of these $15 master cylinders and they are all still in use, working better than the OEM unit they replaced.

Hope you like it.

BTW fellow inmates, Brak is the new owner of Ilsa, She Wolf of the SS(Super Slab).  She got to be a bit much for this old fart to handle and he offered to give her a good home. 

She always did well by me and she should do the same for him as I'm sure he'll show her the TLC she needs.
