I will be using split copper pipe to protect the 51mm/2in. alum frame tubes from the compression of the muffler clamp mounts. I can't see how a copper pipe shim and a quick wrap w/hockey stick tape could hurt.
ETA: I don't mean to beat a dead horse. My initial build demands that the alum tubes be shimmed. Any ideas? Thanks in advance. be well. J.
