"The issue for SC owners I believe, is that they can't bore out their cyinders because they have the groove at the top."
(laughing)...Chris, you must realize that for an SC owner on the verge of a top end rebuild (BTW - My engine yolk just came in - hide the power tools !!), this whole debate is like Chinese water torture. Everyone seems to either have rebored cylinders or know someone who does. But I can't find a machine shop to actually DO it for me. And both EBS and Andial said the replacement 98mm cylinders for SC's are out of stock.
Aaaaaaaargh !! It is killing me....
