500 Two-Stroke Tech

Trying to help out a friend.

He wants to make a pipe for an 80cc two-stroke engine. He has acess to a roller and TIG.

He doesn't have much money and needs a basic pipe designed.

Any free software out there for pipe design and cone templates?

Thanks!

Here you go - not exactly "software", but...

Thanks, but I should have posted this:

The dude lives in Latvia. So not sure he can use those technical articles.

The bike is a 1983 honda mbx80, hc04. Really similar to jdm nsr80.

Still looking for some free software. I guess if nothing is out there, I could buy him some inexpensive software to help out.
