There is a formula for getting the smell out online. I have done the tomato juice thing on 1 of my labs that didn't like to leave them alone either but all it did was mute the smell. i still couldn't stand him near me. Will see if I can find a link for you.
Edit, here it is. Not sure if it would hurt a bikes finish or not.
