Much thanks to Aaron, Mark at Motostrano, and everyone else who posted up offers for help. Was heading down to Motostrano from Alice's to check out some auxiliary fuel canisters for the KTM, and while stopped at a light about two blocks away I noticed a loud clacking sound from the engine. Nursed it gently to Motostrano and decided to not ride it any farther, and tried to post for help... zero internet connection on my phone at Motostrano, despite full bars of reception. WTF? Mark was kind enough to put up a post for me and put me in touch with Aaron, who dropped everything to come down for the rescue. KTM was dropped off at The Motor Cafe, awaiting diagnosis...
Again, huge thanks to Aaron, I believe I owe you two, now.
