Chris, If you'd care to try a KLR I have an extra. I can have it ready to go by the time you arrive. It is a '92 with 13,000 miles on it. Ready to go means,new tires.chain and sprockets,doo-hickey upgrade and generaly tuned and tested so that I would be satisfied it was up to the task.
I have 3 1992 KLRs. The 1st was bought as a non-runner with no papers.It is slated to be a sidecar tugging farm truck replacement. The 2nd was bought as a 8000 mile non-runner from e-bay at present has 26,000 miles and is my travel-utilabike. The 3rd is the one described above, also a e-bay refugee.
I live about a hundred miles from the eastern end of the T.A.T. I have bought the Tn. and Ms. portions of the route and plan to ride that part this year and do the rest as time allows.
ride,smile,repeat as nessasary
