First, I'm rarely at home, usually working somewhere far away. Second, I did, but he was convinced you methods would work. Progress wasn't made until he went with formulas found in the two stroke Bible. Even then there was experimentation that had to be done. Altavillan has been doing a lot of the same work, but along a different path and the insides of his engines don't look any better than the other one. I can put 500 hours of hard running (doing it frequently) on an engine with an extremely restrictive exhaust due to noise constraints before they look as bad as what I've seen with theirs.

Much of pipe performance starts with the port designs, timing, and induction methods used on a small two stroke and the piston port engines don't tend to work as well with a pipe as the rotary intake design. Even the standard reed intakes are behind the rotary designs in that aspect. Many of us are not retired with the time available to play with things as long as we might want or need to.
