Anybody have the engine specs for a 1981 Express Sr NX 50?
I want to build an expansion chamber using the exhaust calculator app. Need to know exhaust duration, port size, width, height, length, and a coefficient. Thanks on advance.

You'll need to do the measuring yourself on that. It seems just about every variant of express has slight differences about some or all of it's details.
I was hoping to not have to tear it apart.
It's a scooter with tiny lil tires...………..should be in OFF TOPIC forum Bob.
