Elvis Motorcycle

My friend just acquired a motorcycle that the previous owner swears Elvis rode in one of his movies.
However he's not sure which one. He thinks it may be a Hawaiian film.
I know there were 3 motorcycle films that Elvis did but I don't think it's any of those.
In other words the motorcycle wasn't a key feature of the film. I think it possibly appears in only one or two scenes. Not sure though.
It's a California registered bike, and in CA vehicles keep the same plates for the lifetime of the bike.
The previous owner claims that the license plate is clearly visible in the movie as Elvis rides away on it.

It's a 1962-63 Red Honda Dream
License plate #: 154613

Can anyone tell me what movie this bike appears in?

Here's a link to what the bike looks like: http://lh4.ggpht.com/themotorcycleshopsa/RqfJa2wNlAI/AAAAAAAAAKE/au5PAX5xepY/s400/100_0017.JPG

Your help is appreciated.
Thanks!
