Jeez david, that's horrible. Take care of yourself dammit, I don't want your next post to be your wife on your account giving us an invitation to your funeral! How long are you off the ankle? Maybe I can come and visit when my engine's broken in (bike comes on tuesday, I get the first Streetmate in Canada and I'm obviously following the proceedings here with great interest!) if my exhaust survives that is.
I don't have any welding tools and I'm very, very bad at it, so it'll have to be a shop that does it for me or a new pipe. Although for the first time this happens I can probably get a new pipe out of Mr. Moped.
I think it's retardulous that the Tomos exhausts are welded totally shut... my old moby pipe parts bolt together (well, you can take the end off anyway, but that's more than sufficient) and get at the inside without actually cutting the damned thing open.
