Yesterday, my friends son asked to help work on my '13 RIII Touring, so I told him how to check the oil (run engine briefly, shut it off and wait 10 minutes and check the dip stick). I then told him to add a little oil if it was below the lines on the stick. I guess I wasn't clear enough when I didn't explain that the level should be between the two lines! He thought I meant that the level should be above the top line! Now I have about a quart of oil too much. Is this going to harm anything? What should I do short of trying to drain off just a quart?
