Cam chain shoes? Get it checked ASAP. If the shoe(s) fail completely, you are in for a big expense as it spreads broken pieces throughout the motor by poor design.

Not enough! LOL Most are .475 at the valve with far too little duration, even for the fat bikes.

After you modify your air cleaner and exhaust, a good set of low/midrange cams will really wake up that Road King. Stick with the torque cams, not the high RPM grinds the lighter Superglide guys run.

Is the tranny oil full? what kind of noise? Is there any grinding or other noises, or is it a whining sound? Does the clutch adjustment seem any differnt than it was prior to the noise? I would start with the throwout bearing, first.

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.

Where is the oil dipstick on an 03 road king

The oil dipstick is located on the right side of bike almost directly under the football cover for the air cleaner. It's a round knob that pulls directly out (Kind of wiggle as you pull on it). Just check like a regular car dipstick pull, wipe and reinsert and then look at dipstick.

Rubbing or grinding noise in steering wheel

Hi, this could be a combination of many issues. i would check the following.

Check the strut mounts. there could be some damage here concerning the mounts. i would also check the control arm bushings as well. check for damage here. I would also inspect the CCV half Shaft as well. this is a known problem spot(re manufactured)CCT.

The last problem spot here will be the actual wheel bearings in the front. they may be worn or dry. this could cause the symptoms you stated as well.

you will find the issue in one or all of the above problem spots stated.

Please rate and god bless:)

Grinding noise front end when slowing down result in cupping tires , dealer replaced tires 4 time an gave it a alinement 4 X car has 20,000 mile every 2,000 starts again

Do you have aftermarket rims? If the rims rub against an outer tie rod, it will destroy tires. Any kind of suspension modification can cause this also.
