Flex-Hone Tool-BC25832 Brush Research Cylinder Hone, BC Series, Silicon Carbide Abrasive, 2-5/8" (67 mm) Diameter, 320 Grit Size

Worked well. Make sure u order correct size for your cylinder. Not badly priced

Bought to clean up the bores on a 1974 Kawasaki S3 Triple (400cc). I was worried that conventional stones would jam in the ports.Bought this and it did a fantastic job! It’s a tight fit and you fling oil everywhere when using - but it does a splendid job and leaves a perfect crosshatch pattern of light hone marks.Watch the videos first and be prepared for major clean-up of work-piece, bench, ceiling, you……

Superb quality did an excellent job

Good staff ,higly recommended.

Super finish

I use this to hone transmission tail housing bushings when they are a little undersized when pressing a new bushing in. Works very well for this.

Works good

Better than stone hone

Works fantastic for cleaning rusted bushing tubes.
