Boring how far?

Just a "wondering" ? I see Mikes has the 80 mm 750 kit, and oversize pistons up to 4th over at 1mm, with rings up to 6th over 1.5mm. What is the most it is safe to go with the oem cylinder liner? I see Hoos has JE 700cc kits. I'm guessing that would be about 2.5mm over? Does a 700 use the oem liner?

The Hoos 700 kit uses standard liners bored out, I'm on the maximum you can really go at 78mm, 707cc, not sure the size of his pistons he doesn't state this for the 700.

His pistons are 77.5 mm. I went this way, works fine.
