Interesting idea, I'd be happier using this on a bike that had a bottom mounted sump plug. With the Fazer I tend to leave the bike on the side stand for a while as it always seems to have a small flow of oil once the initial gush is over with and a wander if the internals of this plug would interfere with all of the oil draining out, perhaps it wouldn't matter in the scheme of things if a few cc's of old oil remained, just throwing it out there.
