My dealership did my first oil and filter change along with other service on my used 2007 Griso. Was in the process of changing my oil and filter today. The guy I bought the bike from gave me three new HIFLOFILTRO HF 551 filters for which I have the appropriate cup-style filter wrench. However, when I tried to remove the dealer installed filter, I discovered that it's slightly larger in diameter than the HF 551. Anyone have any idea what size filter wrench I might need for this filter? I'd call the dealer but they are closed on Mondays.
