I had my 1991 FXLR rebuilt. 23 years the Base Gaskets went in the Heat of South Florida. After the rebuild using James best Base Gaskets, about 5,500 miles it started weeping on the Rear Cylinder rear left head Bolt. I always warmed the engine up before riding so I know it's been rode correctly.
I've had Friends who's autos have had issues with Engine Head Bolts coming lose as well as Intake and Exhaust bolts.
I know Harley says no to Re-Torquing but Auto Dealerships address this issue every day. They just put a new one in and Re-Torque that Bolt. Nothing else is addressed.
So I got tired with the Weeping and thought I got Nothing to lose if I do this.
I pulled that rear head bolt off that 1991 EVO.
I used ACF-50 to lube, just the Head Bolt and it does not take much, best stuff in the World, it's like water it's so thin, then I slung out the excess. ACF-50 is made in the U.K., it's used to spray on Jets on Aircraft Carriers. Salt water is bad and this stuff kills the Rust and it last for 2 years, as long as you don't clean with something like S100 or Bike Bright. Protects Chrome too.
Then I was able to just use my fingers to screw it back down to the base.
Re-Torque according to Manual Spec. The Last Torque Value of a Quarter Turn, 90 Degrees is also 42 Foot Pounds of Torque.
Now after a couple months of riding I can attest """No More Weeping""".... Problem is Gone and I don't know if it's just me but it's got More Power.
If yours is weeping or leaking a little you have nothing to Lose, give it a try.

What ever they did I'm sure they did it a long time ago.
