So in anticipation of good weather finally coming I changed my oil and filter. I let it run for about 15 minutes then opened up the 3 drain plugs and removed the filter. No oil was dripping when I put the plugs back in and filter on. The bike takes 5.5 quarts. I filled the filter and started adding oil. At 4.5 quarts the funnel started backing up and overflowing. Big mess on the garage floor. So the only thing I can think of of is that because of the long cold winter maybe I didn't let it warm up enough and the thick oil didn't drain?
