Question about 2006 Harley Davidson FLHR Road king

1 Answer

I'm hearing a little valve noise on my 06 Road King. I've got 14k miles on it now. I've been running 10-40syn oil in it. Should I run 15-50 or just take it to the shop and get the valves adjusted. The noise is not scary loud or anything like that, I just hear it. Mainly on the highway at higher speeds.

Mobil oil won`t cause this problem however if the mechanical parts have just succumbed to metal fatigue or defect.the noise could be rocker arms,connecting rod noise or a failed piston.its hard to say without hearing the noise as it is to try and describe the noise.

How to fix a noise in the valvetrain


If you have a noise in the valve train, you have a serious problem. You engine is equipped with hydraulic tappets just like the ones in a car. There should be very little noise in the valve train. You may hear a slight tapping but if it's loud enough to attract other people's attention, you got a problem. That's as much as I can tell you without a better description of what the noise sounds like and where it seems to be coming from. If it's coming from down on the bottom end around the cam chest, it could be a roller on the end of a tappet going bad. If it's up at the top of the head, it may be a rocker shaft bushing. The bearings on the end of the tappets seem to want to go bad between 25 and 30 thousand miles if they're going to go bad. Now, I have seen them go bad with as little as 13 thousand miles on the engine but then I've seen engines with 75 thousand miles running quiet. It's luck of the draw.

Good Luck

Odds are that you have lost the roller bearing on the end of a tappet. This most often occurs between 25 - 30 thousand miles for some reason. I've seen them go bad in as little as 13 K miles. Then, I've seen them still running well at 75K miles. Just depends on how lucky or unlucky you are. The bad part is that when this happens, it usually takes the camshaft out with it as it scars one of the lobes up beyond serviceability. Time for a nice little V-Thunder cam.

Good Luck

40k miles you're lucky that thing still runs, but it could be a droped valve or a broken retainer clip take the valve cover off and inspect ,if the problem is lower down then just look for a used motor online it's simpler that way and cheeper

Sorry to hear about your problem but it does happen. With the mileage that you are showing on your speedo, I would guess that your problem is a tappet roller has gone bad. This is a problem with Harley's. Between 20K and 30K miles is the prime time for a tappet roller to fail. I have seen them fail with as little as 13K miles on the engine but then I've seen them still running at 75K. Just "luck of the draw" so to speak.

One of the reasons Harley designed the "Twin Cam" engine was an attempt to solve this problem. They thought that if they could bring the valve train geometry closer to being perfect, straighten out those pushrods, that would solve the problem. Like a Sportster. I don't think I've ever heard of a Sporty losing a tappet roller. I don't hear about tappet roller failure as often as I used to and that may be the reason.

Now, keep in mind that without hearing your engine or doing any exploratory surgery on it, I'm just guessing here. It could be virtually anything. Disassembly and investigation is the only thing that will tell the story.

I'd advise doing that pretty soon as well. If you've got metal in your oil, it's doing damage all in the engine. I'd go ahead and take it down if I were you. Good Luck.

Valve noise 2006 road king


Hello redevil67...This is normal for the HD engine, it going to have valve train, top end noise at some point, some as early as 2000 miles. If you take it to the dealer they will try to sell you on worn tappets...key word here SELL..I've seen this many times, dealer replaces componets, 2000 miles later the noise returns.
These are hydraulic valves and as you probably know they operate at zero lash. Personaly, i feel that the problem is that the cams are not hardened properly or machined incorrectly.. When the leading edge of the cam lobes wear to a strange profile it tends to snap the lifter up in the lifter bore. This causes the rest of the valve train to rattle. You hear the noise on top but the culprit makin it, is the cams..Many chose to go with an aftermarket cam, such as an andrews...Another suggestion, is to switch oils. Don't know what you are useing now, but i'm not a fan of dino oil. As the temperature builds the more an oil is stressed. Lucas full synthetic 20w-50 or Mobil1 15w-50 are both excellent for anti-wear and long term protection.
I hope this helps, please rate me a fixya and good luck with your bike.

2001 H-D Road King engine knock


For valve train noise try these:
1. Low oil pressure caused by oil feed pump not functioning
properly or oil passages obstructed.
2. Faulty hydraulic lifter(s).
3. Bent push rod(s).
4. Incorrect push rod length.
5. Rocker arm binding on shaft.
6. Valve sticking in guide.
7. Chain tensioning spring or shoe worn.
8. Cam(s), cam gear(s) or cam bushing(s) worn.
9. Cam timing incorrect.

If it is a bottom end knock, an engine tear down may be in order.

06 Road King Classice shuts off when in 4th gear beloe 50mph


It's normal for the check engine light to take from 0 to a couple seconds to turn off. The computer runs a system check. Put an oil pressure gauge on the bike and watch it closely. If your pressure drops when the bike loses power, the engine may be locking up from lack of oil. Another possibility is your lean-angle cut-off switch is defective. The switch cuts power to the bike in case you lay it down. Harley also has had problems with their fuel injection system losing power for no apparent reason.

Make sure you're using the correct weght for the oil for your area where you ride..the wrong oil can make your scooter run hot, so can being out of time..even by a few degrees.

When you check your oil is the bike warm or cold, and is it leaning or do you stand it upright?
