So at the end of last season my 05 450r took a tumble down a nice embankment. Dislocated my shoulder and didn't touch it until March. When undid touch it I did a full dasa exhaust, changed the main and pilot jets also changed my oils. Tried repsol oil recommended by the counter person in fun wheels honda. Well, after doing all the work, it starts up and runs normal but smoked whitr smoke. I figured at first it was the anti seize from the mid pipe burning off. Second day of riding my exhaust loosened up at the head pipe and noticed oil dripping down. I tightened it up. Let it run a bit and stopped smoking. After letting it sit a couple of days this week, it starts up again with white smoke. Any ideas?
