I will try the plastic bottle trick here. I had the dealer change my oil, because they gave me a free oil change, and they just spun the filter off and let the oil flow all over the frame, etc. Now I have been trying to wipe up all the spilled oil on my Sportster frame. It is hard to get it all out, seems to be pooled in there and slowly seeps out. I will try some brake clean or something next time I wash the bike. You would think the dealer would use something to catch the oil? I complained to them and they didn't seem to care. I am a mechanic and I would never be sloppy like that!
