>>>I disagree with you Ben. Flat 4 engines have a problem that upright
engines do not have to deal with, and that's gravity. The piston is
sideloaded it's entire lifespan, and that's why the cylinders oval out.

Technically I agree on the gravity fact John... I may have less experience
than you, but mine shows a different conclusion.

Anyway, I think there is a lot more important fact to longevity than
horizontally opposed engine VS upright. Anyhow, I don't believe in honing
unless the engine as good compression and the cylinders have nice surfaces.
Everything can be measured! I hope we agree on that.

In the pass, I tried to save money on motorcycle engine with honing, many
times. But I never had a good result. I lost more time than anything else.

On my buss I did slightly hone the cylinder and put new rings, why, because
oil consumption was 0, cylinders and pistons were well within wear limit and
on top I had a OEM set of new rings for my pistons.

Have a nice day.
