Has anyone used a flex hone on their master cylinders before?
-
All K-bikes have Nikasil coated cylinders. They last nearly forever and don't ever require a hone.

Thanks for the tip.
My question was regarding the front and rear master cylinders. Mine have some pitting. I’d like to hone them rather than purchase new ones.

Sorry, I saw the cylinders in the subject and thought engine, not brakes. I didn't clue in on the "master" part.
-
The bores are very small for a hone (12/13mm), but I've had success with rolled-up wet or dry sandpaper and solvent or soap water. No power tools, work by hand slowly and inspect often till the glaze is gone.
Hope that helps. :clap:

Wet and dry slipped into a slotted dowel to make a flap wheel. However I wouldn't bother doing it on the rear master cylinder, a new rear can be bought for $1.33 Au. See http://www.motobrick.com/index.php/topic,9364.msg90596.html#msg90596 Once done you will never have to hone a rear master cylinder again. The price of non OEM cups comes to $10.00 for the extra $3.33 I now have a spare in stock not that I've ever needed it.
