I think that my 73 K3 meets just about all of my requirements, (highway bike, commuter) but it would be nice to have my old 73 350Four back in the garage. It is really the only bike I have owned that I wish I had kept.
For now I still have my 79XS400 Ratbike that will soon become a winter project. It desperately needs a valve job and a general mechanical overhaul, as well as a fresh coat of BBQ paint, but it has been driven to death in 4 different countries and I just don't have the heart to give it up. Considering I bought it in 2004 for $600.00 and have only ever had to replace the battery and throttle cable, it's not really a money pit.
For now two bikes are enough
