Replacement crush washers


New member
Hey Everyone!

Just bought a 2011 FZ8 and performed my first oil change. The crush washer looked ok so I tried to reuse it and, low and behold; I have a slight leak (slow drip) coming from the nut. It's a 14mm bolt so will any 14mm crush washer do? Is this not the case? And, do you have any preference over aluminum vs copper, etc...?

Thanks in advance for your help! Love the bike!
I have been using 14mm aluminum crush washers from Cycle Gear (trackside brand) for years now and I haven't had any issues. They are a little thicker and the outer Dia. Is a little bigger than stock but they work fine!
