Thanks IC, I always did like a mechanical challenge.
I think as long as the bike has some sort of value to the owner, it's worth fixing. I too, feel bad about "blue tarp's diseased" bikes. This has been fun to work on as it's so simple and an unusual model I didn't even know existed. I'll be taking it out today to meet up with my brother for brunch and a ride. I've convinced him to ride his TDM even, a bit of a rare bike as well.
