LOL....Obviously self taught. Don't say that...this kid will grab one out of grandma's junk drawer and put a WASHER on the bike FFS :laughingAfter having taught myself the art of motorcycle maintenance .....
when you change oil you will need a new washer...
What you meant to say was a "crush gasket", buy it from the dealership when you pick up an OEM filter as well.
I'll bet thousands of people don't change that gasket.:surrender
