Just changed the oil last night, if you plan to perform this task yourself be advised....The filter wrench that attaches to a ratchet is a very good idea. I do not have one, but I think it would have to fit a 3/8" drive in order to be used if the bike is not on a stand, Unless you have a very short 1/2" ratchet. Also a fine toothed ratchet or a couple of universals and an extension would make the job a whole lot easier. There is just not a whole lot of room around the filter, and not a lot of ground clearance either. I used a "strap style" filter wrench and the only thing that allowed it to work was the pivoting handle. Also, keep the low ground clearance in mind when selecting a drain pan - had to do a little fabricating! Other than that it's a piece of cake.
