I think I remember using a thin plastic hose - fish tank or hospital type - to snake into the filler hole and pull a little out. If it is long enough you won't get it in your mouth.

Also, I've changed the oil filer without draining the oil - the new filter had a slightly raised center screw hole and leaked when tightened so I had to swap back to the Mobile 1. I have crash bars so I laid the bike on it's right side, removed the filter with no leakage, and simply put on a new one. The removed filter had some oil in it. Also, loosening the filter but no removing it will result in oil leakage at the filter. Not recommended for simply removing some oil - I suggest using some fish tank line.
