I'm not the Jason Bourne type but if I can get past the odd border or two and get copied paperwork then that's what I do to get what I want. I'm not someone who makes problems I'm a born fixer I only see solutions not the problems, I don't BULLSH*T and go by cold hard facts so my perspective is solid.
If you read through some of the recent posts you will see that I'm not the only one that likes to use copied paperwork, just go see Mr Lucky @ Lucky Lucky Motorbikes on the main street in Phnom Phen, and he will supply you with all the correct paperwork stamps seals etc for use in Vietnam. $50 or $75 if he doesn’t like you, smile lots and say how nice his place is, and admire all the stolen motorcycles from JAPAN, maybe purchase some new bark busters at a huge discount, or get him to change the oil on your bike. Then just say 'oh I've never been to Vietnam I've always wanted to ride there' easy yes, no problems.

Right I can't make it anymore simpler can I?
Then all you have to do is turn up at any border town in Cambodia go into a bar, or one of those little local coffee shops and ask who is the best person to talk to, it's normally the guy with the gun. $20US WILL get YOU and YOUR BIKE over the border ANY BORDER but you have to haggle, these people ran guns and drugs for the last 200 hundred years so they do know their way around the paths, just don't take lots of money with you or look too rich.
Then like I said keep a low profile, speed and you will loose the bike, stick out too much and loose the bike LOW KEY is how you have to be. Just remember that the places that you are currently in are all about saving FACE, if they can help out a foreigner then that gives them more FACE in their social circle, have fun respect the people and bribe everyone.
Think I'll change my name to McGyver, now where did I put that paper clip?
