I had the same shaving in mine the first time I did an oil change on my 750. I'm pretty sure none of the previous owners ever did an oil change from that drain plug.
If I remember correctly, the manual says to use the other drain plug for oil changes, and makes no mention of the side plug.
The same is true for the VN900, manual says to use the bottom center plug and makes no mention of the plug on the side for oil changes.
Hell, the mechanic at the dealer gave me a funny look when I first bought and picked up the bike and mentioned doing all my oil changes from that plug. I tried not to laugh when he said the oil will drain better if I use the bottom center plug and keep the bike level and upright.
......I'd rather wake up in the middle of nowhere then in any city on earth.
