Numbers are interesting and thanks all for voting. 6.75 to one would prefer American made and almost twice prefer more power. Last one, I thought would be higher.
Did the math on my fingers but think I'm close. Not that it's all that an exhaustive research.
If an American kit /engine ever does come to the market, would be really cool if it was uniform, other vendors could come out with all sorts of after market and upgrade stuff. Just a thought. I for one really enjoy tinkering and trying to get them less or more of something. Power, sound or speed. All mostly the fun of experimenting for me.
