OK, I have been fighting an oil leak, from of all places, the oil plug. I have tried multiple gaskets, seals, whatever.

I'm on to plan B, which is installing a new plug. Anyone happen to know what thread it is, so I don't have to go through more quarts of oil?

Thank you, Brian

Mine leaks too, but only a drop or so a day so I haven't put much effort into fixing it. I thought about a new tighter fitting copper washer as mine seems a little oversized. I'm afraid to put too much torque on it in fear of ruining the threads in the tank. You could try to get a good fitting copper washer and anneal it then tighten it down and see if it works better.

I don't know the thread pitch off hand, to not answer your original question.

Years ago I had similar problems with what I originally thought was the oil drain plug leaking. As it turned out in my instance it was that the oil tank was actually leaking.

I replaced my tank and everything has been fine since.

I had the original oil tank welded up and now it's a spare - that I haven't had to use,

It is 1/2-20 thread.
When I changed the oil on my bike the first time the threads came out with the plug. So I bought a first oversize plug as a temporary fix and it is still on the bike three years later.

Check for burrs and nicks on the sealing surfaces. You're using a copper crush washer?

Thread is standard SAE american 1/2 X 20 national fine pitch.
I have two tanks and both have helicoil inserts in the tank and I've assumed they were there from the factory so owners didn't strip the threads out of the aluminum tank. I made a fiber gasket for mine out of really dense gray fiber material and I cut the center out with an xacto knife small enough that I had to thread the washer onto the drain plug so it was a nice snug fit around the threads. I only have to tighten it up snug and it doesn't leak a drop of the high priced slippery synthetic oil in the tank.

The only material I have yet to try is a copper crush washer, however, I think 1313 was onto something. Upon further inspection, a closer look revealed a very short hair line crack on a backside welded seam. I ordered a 'good' used tank. I'll bolt that one on with fingers crossed and have the original tank professionally fixed. Thank you for all the replys. The help is very much appreciated!

Changed the oil about 1000 miles ago, and today I've got a major leak coming from the plug area, at least that's where I thought it was coming from. Wasn't able to dig into it due to the fact I was wearing formal office attire.... lame

Awfully glad I didn't plant the bike on my ride, the back tire had a fair amount of oil on it and I was enjoying HWY 74 through Ortega Canyon

Any other suggestions that aren't posted in this thread for fixing this?

Thanks

Try a nylon washer and/or thread tape. Both have worked for me in the past.

I have had a bad weld and had the washer leak problem at different times. I had the welds redone and as some have mentioned, I replaced the copper washer with a high durometer nylon washer. The nylon will hold up to the heat and also allows you to tighten down a bit without fear (too much at least) of stripping the threads. Which has happened to a friend, he went to nylon after a heilicoil as well. No problems after that.
