I washed mine reaaaaal good when I got home from the Gap.
...and no, you're not the only one. I put dressing on the walls of my tires, the hugger, & other pieces parts such as the black cable housings & such. I even clean the bottom & insides of my swingarm, and scrub the bottom & front of the engine. Show room clean is how I like it. The only real issue I have is getting all of the bugs out of the radiator... but other than that, it's gotta look like new when I'm done with it & ready to ride.
Abba Zaba, you my only friend.
