I recently bought a '72 Honda CB750. There is a small oil leak (just a consistent but seldom drip) from the oil drain plug underneath the bike.
The other day I went to change the oil for the first time and found that the plug seemed to be stripped because I kept turning it and it wouldn't come out. I was able to turn and shake it enough to get it out and when it came out, in the threads of the plug, were metal shavings. When I cleaned it off, the drain plug seemed totally fine. I'm gathering that the thread shavings came from the drain itself and when I reapplied the plug, the leak persisted.
Any ideas on how best to fix this. I'm a novice when it comes to motorcycles and mechanics but I'm here to learn.
