I'm looking to build a set of expansion chambers and I can't find a set of plans. I have a 1970 250 that I'm currently rebuilding the entire bike. So if anyone knows a good resource for expansion chambers that would be great!!!!!!

Jemco sell a set for the X6 but they are copies of the factory race kit pipes and not suited to street riding at all.

I have heard of people modifying DG pipes intended for an RD350 Yamaha. They supposedly work quite well. I have no personal experience with them though.
