I stopped by a Yamaha dealer to pick up a quart of Yamalube 2S. The bottle label looked different and on the bottle it said NO SMOKE. I'm guessing this is something new? Anyone using this? I personally would like to see smoke, I'd be a little nervous not seeing smoke.

I saw that version (blue label) at my local dealer but also the standard 2S that doesn't have the smokeless label (red label) The official yamaha site only lists the smokeless version but you can still get the original at shops. In fact the description says it "reduces visible smoke" so I think it's not entirely smokeless. Probably because it's semi-synthetic. The 2R (racing version) doesn't make the smokeless claim so maybe go with that if you prefer.
