The oil filters are real easy to change using a socket style filter wrench and a wobble extension using the hole in the center stand. It can be done with a regular extension but it tough to keep the filter socket cap on the filter. With a wobble extension its a snap
I have had a hard time finding a wobble extension (wobbler) anywhere. Where did you get yours?
I really cold have used one when installing the centerstand on my Wee.
