there is an Auteco dealers in Bogota (Kawasaki) on the left as you come into downtown (forgot the street name) but it is the main street coming into Bogota from north, when you get into the city look for it, it's about 15-20 blocks north of the downrtown , small sign, - ask a local rider they are really helpful - if you pass the Suzuki dealer on the right you've gone too far.
that have repaired a couple of KLR's that I know about and done a good job. Also in Bogota are lots of moto shops in a few block area near Candelaria,
I know how you feel I did the same and changed back right away.
in Costa Rica
panama...I don't think there are any.
Medellin - go to Ruta 40 BMW shop they can find it if anyone can and are very helpful for all bikes
Cali-ask Mike at Casablanca hostel he knows local Kawasaki shop owner or email him (he's posted ALL OVER here) :-)
