I love being able to buy your product on line for a motorcycle that is almost 30 Years Old (1986 YAMAHA FJ1200), and I was excited that it came with the O rings; however the big O-ring was too big. It would not fit in the filter housing. I don't know if this was due to a cross reference error, or just a packaging error; after all the bike will be 30 years old in January. I wasn't upset and just added the big O-ring to a list of [Name Brand] I was ordering the next day. I would buy from you again.
