Living in "Latin America" I wouldn't take such an old bike for that kind of trip, I know that getting parts for new bikes is a PITA, but it is twice as hard to find parts for older bikes. A newer bike will be more reliable and your chances of not needing spare parts during the trip will be much higher.
What bike would you recommend that would have the best chance of parts availability in "Latin America"?
In other words what do the locals ride? I rode a 1982 GL500 down to the Panama Canal in 1997 and it was plenty of bike. Luckily I did not need any parts other than a new battery in Guatemala.
A modern air cooled, chain drive, simple 250 cc bike would be fine with me.
