Yesterday after riding a moto, I checked the oil. I had just done an oil change before riding, and when I opened the dipstick oil came gushing out. I thought something must be plugged in the system, so I pulled the oil filter to make sure it is in right, it was (can't go in the wrong way). I pulled the oil screen and it is clean. After I went home I drained all of the oil and refilled with 1000cc and everything is normal. When I change the oil I only pull the plugs on the bottom end, not the frame as it never has any oil left in it when cold. I think there must have been oil in the frame from when I changed it and then over filled when I serviced it. I know the error of my ways now (warm up the bike and drain the frame also), but I just want to see if anyone has any other ideas about why the frame would have some much oil in it. The bike ran perfectly the entire time, and didn't belch any smoke or do anything abnormal. Sorry about the lengthy description. Any other ideas?
