Ahhh yes, thats why I like this place - thanks so far everyone, it's always good to get sound answers from people in the know. I thought you could bore the stock cyls, but I didn't know how much. Looks like I'll be buying the P/Cs together as a kit.
What's involved in clearancing (correct term?) the case and getting the heads to fit? I like the 100s Otto, I could very well be interested.
But if the work involved is too much, then I'll maybe go with 96 or 96.5s?
Just all preliminary, getting ideas as I get closer....
