Be honest. I have always done all the maintance on my bikes and 3 prior busas I had. I never replaced the "crush" washer though...but never had a leak either. The parts guy that sold me the oil and filter gave me one ("crush washer") and said it has to go this end up and I couldn't remember.
My 06 did not come with a crush washer.
It has a solid aluminum washer OEM and I never change it.
