I have a 2002 883C that I've had since Spring 2005. Only about 5500 miles on it. I checked the oil level before firing it up this spring and it was the same way I left off last fall, with the oil on the cold mark at the bottom of the dip stick. After about 5-8 times out since then, I checked the level again, and suddenly it is at the "top" of the tank almost coming out the top hole. It was never anywhere close to this high all last season! I started it up and let it warm up. Checked again, and it was coming out the hole when I pulled the plug. A few days later, I repeated the same cold and warm checks with the same result. Any idea what is going on???
