I need to remove .008 from my cylinder to get to the next sized piston (67.25mm). Can this be done on my own using something inexpensive like a ball hone or will that not take enough material away?

.008 is a lot to try and do on your own with a ball hone. I think it would be almost impossible to keep it true, it needs to be put on a machine and bored

It needs to be bored if it's a steel sleved cylinder or it needs to be resized and replated if not. You will not get it with a hone.

Is it Nikasil lined? is that .008 per side or .004 per side? either way way not happening. If it is a steel line cylinder and ball hone may do remove that match but it wont be true, round or straight.

The cylinder finish is the single most important part of making ring seal. Followed closely by piston ring groove flatness.

If you take .008 out with a dingle berry that cylinder will no longer be straight or have the proper finish.
