Leaky derby cover

Well here it goes, my buddies 99 road king with a twin cam 88, he serviced it now the derby cover leaks when on the side stand , we changed the gasket, and its still drips even after new bolts we replaced on the cover as well, I am thinking the derby cover must be warped, any thoughts?

When all else fails, hell there is always beer!

I have a hard time imagining a derby cover warping. I would check the Gasket and make sure it is good. I would also look for any obstructions that are keeping it from sealing completely. Check the area where each screw enters the primary cover and be sure nothing is bulging out.

Put a piece of 2x4 under the kickstand. Remove the derby cover, use a turkey baster to remove 1-2 oz of primary fluid. How much fluid was put in at the last change?

Inspect gasket if there are any tears or gouges, replace it with a new one. Clean the gasket surfaces thoroughly on the primary cover and the derby cover, place the gasket onto the cover, put the bolt through the cover and the gasket at the 12 o clock position, start threading it into the primary cover until it is secure but not torqued. Put the remaining screws back in place and torque the screws in a criss cross pattern like torquing a wheel on a car.

I suspect that too much primary fluid may have been used in the change.

I will look, but tried 3 different gaskets and still leaks, I wonder if he over filled it?

Good possibility it is overfilled, the older bikes with the 5 speed trans took less primary fluid (32 oz) because the primary cases are a little different than the the newer six speed bikes (36 oz).
It still shouldn't leak even though the primary has too much fluid in it, you could swap out derby covers and see if that helps the problem.

You said you replaced screws? Are all the right length? Aren't bottoming out? I could be wrong (it's been a long time) but are all derby cover screws the same length on earlier years or are they differt lengths? Sounds like a screw is bottoming out and your not torqueing the cover down just tighting the screws.

make sure there is no oil in the grove for the O-Ring, the early twin cam came with a large O-ring to seal the derby and that has been replaced with the gasket you have , if oil gets in the grove from the old o-ring it can leak out
