Hey
I am interested in fabbing a pipe for a variated moby, but before I start, I would like a bit of reading on the basic theory behind small cc 2 stroke exhaust pipes. I assume there are some expansion chamber ratios and whatnot that i could use to build a better pipe than the stock one.
So, anybody have experience with this type of thing/a good website for some reading? I know paul V. has done it, with a pocketbike exhaust and some hacking and welding.

Oh, silly me. Should have looked at wiki first. I will smack myself in the face for that one.
Still, please share any exhaust fabbing info you feel is relevant.
i love how JATO rocket is in the perf section.
I have heard talk of a computer program that you input your engine specs into and it draws you a diagram of what your pipe should look like. I think you might have to dyno it though but I donno.
julian - if you want a nice printable version of the expansion chamber part of the two stroke tuners book heres the one i used. ive hosted it here:

hopefully i linked that right so its clickable.
Hey Doug
Thanks for the link! I will check it out.
Great weekend by the way! I am anxious to grab that moby from you. Maybe I can come up this weekend.
