Don't get disappointed right away. I do understand your position, but as I sad before, every manufacturer who will try make AAC on conventional design, will sooner or later face this problem. We pass this problem years ago ( 1980's) and since that we don't use AAC ( I know for fact that one of my P/S set out of AAC been use by very high ranked racer and it was very successfully, he won a lot of competitions in Europe and in Asia, but sleeve was glued to crancase) on conventional design. I might be able to help later, but at this point I have nothing to offer for Sirio engines.
