Those two were just bad ideas and stuff I don't want to do, like over inflating the tires in an attempt to squeeze out more. Stuff I'm really not all that comfortable with.

As for the cylinder head thing, that's something I haven't really been able to work out well. You can port and polish, but where is the stopping point? There must be a sweet spot somewhere, and if you go over that, now you have to spray more fuel.

But there comes a point where you increased power by doing that, and thus you might have increased efficiency somewhat.
