it doesn't smoke on startup at all, it runs fine, its just when it gets abit warm and its idleing, if you rev it an let go theres smoke that comes out and it kinda drifts away, then kinda clears up and just looks like condensation, but as soon as you blip or rev it again same thing, she chugs out blue smoke whch look abit white aswell.
Also it smokes very bad when u take the yellow oil cap off while its running. So u take the oil filling cap off and she starts belching smoke out, put it back on and she kinda calms down abit. It runs on when u take the oil cap off, it doesn't cut out or anything.
cheers
