2 strokes in general like to be ridden hard, on the pipe, especially 125's. Most people who know how to ride 125's, jet them to be ridden mostly on the main jet. However, if your riding on the line between pilot and main, mostly using the needle, yes it will be more smoky because you'll be loading it up and not letting it burn off the excess oil.
Oil ratio, jetting and rider ability all go hand-in hand. A ratio/jetting for one person may not work for another, just because of their riding habits/style. So too much spooge/oil burning off can mean a lot of things, jetting of course being one of them.
If you can stay on the main jet (throttle pinned) everywhere, you most likely won't have any issues. I have yet to own a 125 that hasn't been a smoker when at idle or low RPM's, so you may be OK.
