Sounds Normal
Bluish white smoke means your combusting some oil... Perfectly normal in a two-stroke, not quite so reassuring in a 4-stroke...
If you want to see some SERIOUS two stroke smoke, fly nitro fueled Radio Controlled helicopters... You run those motors rich to help cooling and sometimes you lose the Heli in the smoke while hovering :)
Now, if you were to be riding a two-stroke dirtbike that was obscuring you in white smoke, I would call that excessive as well :)
Have a good one!
