Does a good job. Take your time when cleaning the cylinder out to make sure you get all the chips out

I had a stripped out head on a 2005 Harley Dyna Lowrider and this was the perfect solution. Saved me a lot of money because I didn't have to replace the head. It was easy to use and worked perfectly.
