I learned something a couple of days ago that I like. I've been looking at open transfers and thinking of a way to get more out of them.
I had several wildthings sitting around so I tried something I've not seen yet. Someone has probably already done this, I've not seen it though.
I figured out how much of the transfer is uncovered when the piston is at BDC. Then I widened that much of the transfer port toward the intake, I added about a third more area to the port. It really brought the little saw to life. Of course that's not all I did to it, but I've ported several of these small open transfer type saws without being too impressed, but this one screams.
