Howie,
If you look back through some old threads, you'll see one where I slowly developed Elvis in the direction you have taken Cybil. Once I got to where you're at, a funny thing happened. My best bro Matt (Screamin_Beagle) looked at the bike and said, " you know bro, a Road King was never intended to be what you've turned this bike into " At first, I was a little pissed with him because I'd put a lot of thought, time, effort and money into getting the bike where it was. But, as I sat on the side of the hill above his driveway and stared at the bike, I knew he was being what a true brother should be - - - - honest. And so began the stripping down of the bike to the basic SERK and then the re-building process that ended with the over the top Elvis that MJZ now owns. And I can tell you from the PM's I've gotten from Mark, I made the right decision. He has an 05 Banana that he used to think was the greatest motorcycle ever made - - - until Elvis came into his life. Now he spends his time trying to get the Nana to Elvis status.
I know that an Electra-Glide, a Road Glide and a Road King share a frame and many many other parts, but they could not be more different from each other. So here's my advice to you Howie before you get any further into this project.
Go buy an 05 SEEG and build a road bike for you and Mrs Hoist to enjoy on those long hauls. Strip Cybil down to fighting weight and enjoy your SERK for what it was intended to be. Trust me on this one Howie, I have your best interest at heart even if it does seem like I am trying to torch your wallet.
