Hey Frostbite if you need help or something or some tools I live in Phoenix and would like to offer my help if you need it, sound exciting but also a pain in the butt, Just let me Know,
That's a great offer Tom, and yesterday I definitely would've taken you up on it, but the plan has changed thanks to border and motor vehicle regulations.
Shipping by USPS was not the issue at all. I spoke to them this morning and the only item that was questionable was the rear shock, and I had no problem shipping that small an item by dangerous goods methods.
The gas tank had to be thoroughly flushed out, as did the carb and the engine, so they contained no residue or gas or oil vapor.
The problem I ran into today was importing the bike into Canada. It seems that people regularly try to smuggle kit bikes which are not legal in Canada, by dissassembling them and shipping as parts. Therefore the border patrol watches for motorcycle parts being shipped. If the bike is not easily identifiable as a Yamaha
WR 450, they said it could take months before the bike parts could be identified as a complete WR 450, and I would have to pay the storage fees while it waited for confirmation.
Also, the registry of motor vehicles here won't license a motor vehicle which has been disassembled, unless it is reassembled by an authorized agent approved by the manufacturer. As there are no garages here let alone bike shops or certified mechanics, I'd be SOL.
So it looks like the bike will be coming across the border in one piece, and may even have to fly north in one piece. It was good experience to run through the process though to see what's involved, and to know that mailing a bike is absolutely possible, as long as you don't cross the border into another country.
Thanks again for the generous offer.
