Plenty of naysayers here - questions about how to do something answered with "don't do that". Usually well intentioned, though.
Are you going there, and bringing your bike? Or, are you
riding your bike there? We're assuming the latter, but I'm not quite sure.

http://www.enfieldmotorcycles.com/forum/index.php/topic,18593.0.htmlThere's a young couple who sold the farm and are on a long-term, round the world ride. They're currently side-tracked in Croatia due to a family crisis, but they spent
a lot of time in Mexico, Central America, and Northwest South America - they're taking the slow, scenic route! Anyway, they've got a blog (well written, entertaining, great photos) which will take some time to get through, but you may find some useful information there about logistics.
Their blog site is just their entries. They're also posting the entries on the ADV forum, where you can read the same entries, accompanied by lots of input and comments from people following along. This is an even bigger slog, but you might find even more useful info as the huddled masses chime in. Your trip isn't until next year, so you've got time...

Sorry, I don't know how to jump to the middle of a thread there. It's post number 527 in the above linked ADV thread.
And just for fun, here's a link to another blog they wrote, about their travels in India on rented Bullets:
http://www.ridedot.com/india/index.htmlThey rented bikes from Lalli Singh, and spent two weeks in some truly horrendous weather! They had some trying times, including the usual: road works, break-downs, food-born illness, tourist issues... and write about it with honesty and an interesting perspective.
