Blue smoke, definitely oil smoke. It only does it after sitting overnight, if I restart it after fueling or stopping for a few minutes, there's no smoke. It's not using oil that I have noticed and runs normal, not down on power at all. My thoughts are rings or valve seals. I was considering buying the high compression piston kit and new valve seals and redoing the top end anyhow before this started. Am I on the right track? Should I just leave it alone and continue to ride it and save the kit for later?

Mine has done this randomly, +/- 1/20, only on cold starts since I got it, maybe only when the ambient temp is 10 C or below. No comsumption. I've assumed stem seals, but dunno, and don't worry about it.
