just wondering

[Old Head]

If you replace a piston and rings in a perfectly running motor do you have to hone the cylinder before the new one goes in?

[prepracing]

its suggested to hone so that the new rings will seat in properly, just depends on how your cylinder looks. If it still has good crosshatch showing I don't see any point in honing one

[pit/wood]

new rings should always have a sharp surface to seat.thats the way i learned it.if you do put new rings in and they wont seat,there is a way to help them seat.
