Bossit - I'm sorry we couldn't help with this, it's too short notice. We have limited information on shipping by boat into KL, although Mika Kuhn did it in Oct 2000 from Japan. His total costs, including freight and paperwork in both Japan and Malaysia were US$380. "for a Yamaha Ténéré in a BMW F650GS crate = Export customs clearance $54, Shipping to port $90, Ocean freight $147, Documentation, handling charge $90."
So, it sounds like the charges at the KL end should only be about US$90.00. But if you have to deal with it yourself, it might take several days more than using an agent - it's a tradeoff.
But for Cameron, if you are sending by sea, I suggest you contact Amran Parimon from the HU Community in Kuala Lumpur for suggestions on who to use for clearing the bike. Go to the Community page:
select Kuala Lumpur and fill in your message at the bottom.
Please let us know how you go, the information will be useful for future travellers!
