2-3/4 inch 320-grit Flex-Hone for small engines with a steel/cast bore. This is a very popular hone for Briggs and Stratton 6.5HP Animal, World Formula and 6.5HP Honda/Clone kart racing engines. Hone can be used in many other applications with a bore range of 2.750 +/- .100.

Also available in 180- and 240-grit for a coarser finish.

Hones can be used as a cylinder prep (deglaze finish) during ring replacement. Simple to use and self-centering during operation. See our How-to guide for tips used by the pros for a perfect finish.
