What size is an '85 200x piston .50 over?

title says it all...... thanks

.5 millimeters, as in .020 inches? That would make it 65.5 millimeters iirc. Most people would say "20 over" to describe this. I have a 65.5 Wiseco in mine.

Dude...c'mon, you have asked the same question twice in two different threads. Clean up the posting and have a little patience with the responses.
