Expansion chamber 50cc to 125cc?
My target size is 90cc, nothing available for my specific application (Honda Aero), so I'm going to have to cut and weld anyway. I have a NOS 50cc chamber here, but the RPM range is wrong (too high), probably better off with a 125cc chamber.
Anything out there? |

I have an exhaust that was originally installed on a CT Baja 50 four stroke (hear me out ). The Yamaha PW80 was so faithfully copied, that the manufacturer stuck an expansion pipe on the four stroke engine. You can imagine how long I left that on there.
The only other spare two-stroke pipe I have is from an old YB100, and it doesn't really have an expansion chamber. The PW80 style chamber is yours if you want it.
