Any had white smoke appear intermittently from their exhaust? It has happened couple weeks ago, but it was cold so I thought it was just vapor. It will occur for a few minutes then go away. I had it happen again on sunday while at a solo event. It was white smoke looking like vapor. I went up to the line and of course everyone was telling me bout it. After I got back from the run, it was gone and never returned. It didn't smell like oil, so I am guessing it was coolant system. Anyone had problems with coolant systems?
