Did mine today. Echo most of the thoughts above. I'm not installing a valve; wiping a smudge or 2 of oil off the bar is not a big deal to me. The filter is very awkward to reach. I have a filter wrench that fits over the OEM / replacement filter (3/8" drive) and with enough 'encouragement' (and general grumbling about "likely descendants of Chevy Citation engineers") got it to slowly turn, then removed the wrench and ratchet, and finished removing it by hand. The ziploc bag trick works reasonably well, thanks to all who recommended it. The new filter is slightly more than hand-tight, and should come off with less effort than the factory-installed filter. @nburd, would love to hear more about any success/failure with printed wrench should you go that route in the future. Was contemplating something similar. Thanks!
