Oil leak from motorcycle drain plug?

I changed the oil on my CBR about 300 miles ago. I replaced the crush washer on the drain plug as well. Ever since then there has been a slow leak of oil from the drain plug. Wherever I park the bike overnight there will always be a puddle of oil right under the plug, and the plug is also slick to the touch. How can I fix this?Oil leak from motorcycle drain plug?
There maybe a bit of debri (dirt) under the washer. Then it wont seal right even with a new washer. Next oil change, make sure the surfaces are clean. It would be rare that the plug or the base may have a nick large enough cause the leak.Oil leak from motorcycle drain plug?
You may have to get an over-sized self tapping plug and replace the one you have there. Also, you might want to consider something like this: http://www.fumotovalve.com
Plumbers' teflon thread tape. From your local hardware store.
did you check to see if the drain plug gasket is on the plug?if its gone,maybe you could either make a gasket or buy one.
