Review on 🔸 Cylinder Flex Hone Abrasive - Diameter & Finishing Products by Jesus Baker

This was perfect for honing my 1972 Honda CB350F cylinders. Easy for beginners and gets rid of all those dark spots where piston rings have been stuck and stuck for decades. I used a hand drill, but you can use a drill if you have one. A good tip is to run the drill at low speed while the honing tool moves in and out in very rapid motions. This will give you a perfect 45° hatch, otherwise you might get a sharper hatch angle. Don't forget to use lube as well, I used Marvel Mystery Oil which worked great.
