Drain plug washer

[rooster300ex]

My oil drain bolt is leaking because there is no washer. Do I have to use the honda oem washer, or can I use a 12mm washer from a hardware store?

it has to be cooper or aluminum.

I'm not disagreeing just curious y it has to be copper or aluminum

I was just saying it doesn't need to be oem just made out of those 2 materials so they act as a crush washer. :)
