I asked a Cowlitz County Sherif about it while he had a group of us pulled over for wheelies. He said as long as you're not threatening anyone with it, it's fine.
Some LEOs may try to mess with you, but it's not a problem.
Oh, and when I'm OCing on the bike i ride like an old lady. I don't want to give anyone a negative opinion of OC, so when i OC on the bike i behave like I'm representing the entire OC crowd as a whole. No speeding, no wheelies, no stoppies.... You get the idea.
I think if people saw you pulling wheelies and speeding everywhere while carrying a firearm you might raise a few eyebrows and portray OCers in a negative light.
BTW, what do you ride? Do you have a chatterbox?
