I was actually going to do the same thing that critterdoc suggested! My guy at the dealership told me the glue used to apply the stickers is oil based as is WD-40 and it won't make a mess/melt the plastic parts.
Also In Canada we're told that if we plan on taking the bike to the US (and presumable back) it'd be best to keep the VIN # on as to prove the bike was purchased in Canada.

Splitting hairs here I know, but your bloke at the dealership is entirely wrong.
By "oil based" he means carbon based, or organic.
WD40 is silicone based, which is why it rarely reacts with anything organic, but still dissolves carbon based compounds.
Sorry...I was an organic chemist before I went to vet school.
