Hey hoist sorry to here about your problems with the Road King. I was thinking that I had lucked out and got a good one but I haven't had the opportunity to run mine quite as long or hard as you. as always I love reading your post I certainly know what to look for as for as problems in the future. SO far I have abut 3000 miles on mine and the longest trip is about 600 miles the only problem we had was a mounting bracket for the falsie pipe broke. Since this is just the 2nd bike I have ever owned my experience is way limited but I moved from the SE Fat boy to the SE Road King and it has been an amazing ride I l love this bike so I hope to work around some of these problems before they happen - Just keep us up to date with your road testing
Thanks for the kind words j. Try to be proactive in making sure you don't have issues turn into major problems. The first thing you can do towards this is to take a flashlight and look around your rear cylinder exhaust flange. This seems to indicate the first evidence of seepage past the head gasket. Look all around the rest of the base of the head too. If your rear cylinder barrel deck is clean, then so far you don't have a head gasket leak. The rear will usually leak before the front, but continue checking both. The factory has already modified the head gasket, evidenced by a new, 07A Part Number. They don't do that for chits and giggles. Since there are many more people affected by this right now, I'd venture to say that eventually all will be. Granted, if you don't ride very hard, it will probably take longer. But these engines should be recalled for this rather than waiting for 30,000 people to eventually complain. I found mine and I'm, complaining.
Rocker Box clearance noise can be confused with "pinging", and is more difficult to diagnose. The RB noise will usually be noticed by harder riding, higher revs or very quick throttle openings under load. This is tougher to find if you don't know what to look for. But if you have a head gasket leak, they must remove the RB's anyway. Have them clearanced then.
Lastly, and this is a tough one, is crank runout. This can only be found be either shearing your oil pump shaft and blowing the engine or other issues caused by a deformed shaft rotation, or by actually measuring the runout with a dial indicator on the shaft. HD takes a completely reactive approach to this. Blow your engine, oil pump, etc., and get a new engine. They won't pay to have it checked though. No outside the box or proactive thinking here. Sweep it under the carpet is more like it. Either pay to have this done yourself for your own piece of mind, pay for new cams and have it checked then, or keep your fingers crossed andwait for it to break. Not the best choices considering they put the onus on us to find it, or wait for a failure.
I hope you continue to have good luck with your bike. But take some proactive measures to insure it stays that way.
Hoist!
