How much extra power do you get using the .5mm oversized pistons? Just thinking about reboring ($2 more than rehoning at the shop I go to)

Do piston rings come with new pistons, or do they have to be bought separately?

Uhhhh... none. Or pretty damn close to it. The extra weight of the pistons will cancel out any gains.. BTW hone it at home wiht one of those auto parts hones.... why not. I think I will... just using a drill press.
Cool.

If you are going to do it, might as well put in the 75mm pistons. There is a small noticable difference. Increased compression since the dome of the pistons are higher. Also has valve reliefs. I think they do come with rings.

i can get 75mm rings pretty cheap without having to buy pistons.  about 40$ per set.
