I could just see it. . new motors could actually be "pimply faced" if they had pores!!! Older ones or those that are problematic could get to be a "Boil in the backside", and the ones with the least pores, and best performance, could be called "Smooth and creamy skinned" just like a beautiful woman. . one you want to keep around for a LONG time!!

Seems motors with machined billet crankcases have the best looking "skins" . .at least to me.

Think I'll keep a few around for a while.
