New 520 EXC - Smoke- Anyone else?

I just bought a new ('01) 520EXC and if I crank the throttle I get a little bit of blue smoke. I don't know if it does this when I am riding. Just wanted to see if anyone else has a problem like this. Can't really tell if it goes away after the bike is fullt warmed.

My 400exc does the same and has

done since new. I dont think it is anything to worry about. I beleive that it occurs when a little oil seeps past the valves when the bike has been sitting for a while. It clears after warming up and my friends have told me that they dont see it when they are behind me.
