I work on my personal jet ski and use the flex hone to reseat the piston rings. The flex hone is magnificent, and much cheaper than a machine shop.

Ball-hones are unique. They can be a piece of junk OR they can be American Made and work like the are supposed to ... flexible, range of size (3 - 3.25"), and grit selection. Additionally, price for the quality is very reasonable. Did I mention, Made In The USA.

Got two of these for a friend in Sweden because he needed to tinker on his BMW to up the performance a bit. Unfortunately, he lives in the EU and this product isn't available over there :-/ Too bad, great product he says!!

My husband bought this to hone cylinders for his motorcycle. Worked perfectly. It left perfect striations and looked and felt like it was done professionally at a machine shop.

Phenomenal tool! Highly recommend. Their is reason these folks have a corner on the market, it is an excellent product.I used this to hone my cylinders while rebuilding a 1993 VW 1.9L AAZ engine. Worked way better than expected and I expected greatness! Well done.

This hone is a great tool for making the perfect cross hatch in your cylinder walls. Very easy to use even with a 3/8 inch drill. I recommend to anyone who does work on small gas engines as i do.

With a little practice, it leaves a very nice crosshatch in the cylinders. Worked for me with the drill on about 1/2 speed made about 20 strokes in 30 seconds. This will vary depending on your cylinder bore and stroke...CAUTION: the oil squirters near the bottom of the cylinders will snag the balls.
