I was out practicing today, I washed out in the sand, but kept my bike running. when I stood it up straight to remount, it started smoking out the exaust, very thick white smoke. I shut the bike down right away, a couple minits later I refired it and it continued to smoke,so I shut it down again. I let the bike compleatly cool down and tried again, with the same results. has this hapened to anyone else, and what do you think it could be??? open for suggestions..

i think you got a some engine oil in the cylinder through the cam chain slot. it should just burn off after about 40 seconds
