Gear Oil Drain Plug

[Gene563]

Hey,
I have had a small leak from my gear oil drain plug. I'm not sure if I used a new washer in previous oil changes or not ... I can't seem to find replacements anywhere.
I was wondering if anyone had a line on replacement washers, or better yet, a superior type of washer.
I have been considering coating the existing washer with silicone on the next oil change.
This is only a minor leak ... more prominent when not ridden for a while. Even so, the leak is only about one drip per day; with only an ounce of oil, that could become a problem.
