"promptly fell asleep and woke with dark clouds moving in." Been there.
You even got an outlet by the bed this time. High class for sure.
Since you're a stone mason I do appreciate what you offer on that craft. Keep it up.
As a skilled OTR truck diesel mechanic few want to hear what I can offer.
This ride will be of considerable distance and a not uncommon issue is rear wheel bearings.
Have you thought of carrying a set?
What about jetting for the time spent at high altitudes in the area of The Andes?
Just finished a short RR of a couple doing the TAT and in The Rockies her KLX250 was only good for 1/2 throttle
but his WR being injected had no issue. (The new XT250 is injected btw)
I think of this because of a trip in The Rockies two-up on a Guzzi in the late '80s. It ran like crap.
Stayin' with you on this ride, my best,
