Look, like I told you in your email.

There’s always a trade off with puch one speeds.

You speak of 50mph maniacs but you build an engine that can go 50, then gear shorter so you get great takeoff without a screaming clutch.

A pipe is pretty much required for a one speed piston port stock bore to have any kind of grunt. And converting to reeds just adds to that grunt. Then you gear to whatever max speed you want and limit it so your stock crank doesn’t spin past about 9k.

You can get stock bores to 40 without too much trouble, but low end won’t be great at all without a very tuned braced clutch.

As to the cost, you have to pay to play. This is the cheapest motor hobby around.

A well setup treats reed kit and estoril pipe will do everything you want here for about cheap as you can get
