Primary Oil plug
I changed my transmission and primary drive oils today for the first time on my 97 Road King, and I think all went well. I'm curious about the oil plug for the primary drive. It seems to be more or less like a set screw. How does this stay in place if it doesn't have something to butt up against, or do I not have the right plug? The Haynes manual doesn't say anything about using locktight. I didn't want to over tighten (bad habit of mine) and I'm a little afraid it will vibrate loose.

use mechanical teflon tape
Go to industrial supply house and purchase the Heavy duty teflon tape. Two wraps and it cured a two year leak for me.

Thanks everyone. Looks like I'll be changing the oil again so I can get the Teflon tape on the plug.
