Sounds like a nice trip Jim. I did a similar trip on the other side of the world with a 1974 R75/6 while I was working in Singapore in the late 80s. Me and a group of Brits rode up the Malaysian peninsula from Singapore to Bangkok, with stops in Kuala Lumpur, Penang, and other places along the ocean I couldn't pronounce, then back. It's about 900 miles one way and it took about a week and a half of easy riding. The Brits were mostly riding big twin Triumphs, Nortons, BSAs, and one Ariel that were constantly breaking for one reason or the other. The Beemer, like yours, ran great the whole trip except for a flat tire on the way back. Super reliable bikes with a timeless design and no vibrations.
