I know it's not quite the same but I shipped a Piaggio MP3 in my container when we moved over here from California. It's taken 7 months and it's still stuck in a paperwork black hole in customs. Fortunately they gave me a document that allows me to use the bike on California license plates while they sort it out. They are now telling me I need to get a Certificate of Conformance from the manufacturers before I can register and tax the bike here in Cyprus. It has been one hurdle after another. They also want me to pay 900euro for import and VAT. I'm tempted to just dismantle the damn thing and sell it as spares.
Have you spoken to Gwenny at Red Tape Services ?
She might be able to help you with your problem.
I used her for my importation and registration and she was great.
Her office is in the centre of town .
I will be using her again when I bring over my Triumph Tiger 955i
Good luck.
