I apologize right off, I know the answer if it's a newer bike.
I took the head off my 42 WLA. It has a fresh bore. Fresh pistons 2 over and nice new valves. But he cylinder walls have pitting, but no rust. Deep enough to catch a finer nail on, maybe 1 inch long and 1/2 " wide.
The cylinders I believe are cast. Not sleeves inside a cast like newer bikes.
Is this a porous casting due to old casting methods that 3 sets of rings can handle? Or, is this from someone who just didn't bore the cylinders large enough?
Just run it, or get it perfect?
Sorry if it's a stupid question.
