I bought a CB400 in Bangkok 2 months ago at On-Road Bike ([email [email protected]][email protected][/email]). Since then, I've covered 10,000 incredible kilometers including Kuala Lumpur, the Cameron Highlands, and Northern Thailand via the Mae Sariang to Mae Hong Son to Pai loop (trip report is coming soon). I have one month left now, and I'd like to take a boat down the Mekong from Chiang Khong to Luang Prabang, ride to Vientiane, and then head south to Cambodia to see Angkor Wat and Phnom Penh before looping back west to Bangkok. However, I haven't received my license plate and green book yet. When I bought the bike, I had expected I'd have it by now (I was quoted 6-10 weeks)... but the shop owner is telling me now that it may take as long as 6 months due to backups at the land transport office. So ... the big question: are entry to Laos and Cambodia even possible without a plate and green book? I have the invoice, the paid tax receipt, and a piece of paper showing that the registration has been applied for. I also, of course, have the full retinue of GT-rider border crossing documents. I'm in Phitsanulok now on my way north, as I figured I might as well give it a shot: If I've learned anything riding SE asia for the last two months, it's that most things are possible for 20 or 30 dollars.
