Re: Spec sheet
You might be right. I know one of his engines comes with a mikuni flat slide and one comes with an SHA clone, but I can't remember which is which. The spec sheet is to turn into the engineering department at his college. I doubt they will know the difference between a stock motor and an arrow motor. He should put reed valves and cylinder porting on the spec sheet though. These guys are engineers, I'm sure they know a thing or two about performance tuning in two stroke engines and that info would be helpful to them. But its Josh's spec sheet, he'll present it however he sees fit.
