Here's my fix from a while ago without removing any bolts:
This is a great thread for people who are able to tear the top end apart and then reassemble it. For those who are not able or feel they are not experienced enough I have an easy DIY fix for base gasket leaks... Go to the automotive store and pick up some Permatex flowable silicone windshield & glass sealer. The # on my tube is 65AR. Clean and dry surfaces to be sealed, apply glass sealer onto leak source, remove excess, let cure for 24 hours.
I used this product/method on my '91 FXRP and had no leaks after. Supposedly the glass sealer seeps it's way into the effected area sealing from the outside all the way to the inside and because it's silicone it can withstand the temperature of the motor.
There's your "Do It Yourself" for the day.

If you can let it sit a couple of days you might try cleaning the area where the weep is real good and then try pourable silicone, Permatex 65. Put it on in several thin layers.
You'll be surprised at how good it works. It's only a $5 buck fix too, and if it doesn't work you're only out the 5 bucks. However there is a good chance that it will at least get you through this riding season, and then some without that pesky oil leak.
It worked for me any way.

I think it's a six year old thread about base gasket leaks, and you've got a problem with your rocker boxes.
Don't even thing about resealing them without checking for warpage. Typically the middle one will warp.
BTW: When was the last time you changed spark plugs?
