SOURCE: 2001 H-D Road King engine knock

01road king..probably have 30 to 40 thousand on it...Sounds like cam chain tensioner..about the only thing that will go wrong with your bike. I will assume you have oil etc in it...If you have not been running your bike stupid then nothing mechanical will usually brake on a Harley. Once again I assume its stock. You don't have an oil light on so I'll put my money on cam chain tensioner has exploded or is about to.

SOURCE: when riding 2005 fuel injected harley road king,

Sounds like the intake manifold is leaking. The area where the leak usually happens, are those two rubber sleeves that go from the heads, (Cylinder heads) to the intake. Sometimes the clamp/s loosen up. Sometimes these rubber sleeves deteriorate, and cracks form.

This makes the engine backfire, pop, and idle fast.

The added air at the wrong time cause a backfire, when you let off the throttle. The added air causes the engine to pop, because the exhaust valve has sucked up some cold air.
The engine idles fast, because more air is being introduced, and not metered by the injection system.

(The exhaust valve thing. Exhaust valves are supposed to open, and let exhaust out right? Well there is a thing called Valve Overlap.
The Exhaust valve hasn't closed all the way yet, and the Intake valve is opening.
The 4 stroke engine, (Of which a Harley is), has these four strokes.
1.Intake Stroke. Fuel/air is sucked in.
2.Compression Stroke. The piston comes up and squeezes the fuel/air mixture.
3.Combustion Stroke. The spark plug lights the fuel/air mixture off.
4.Exhaust Stroke. The spent gases are expelled out.

Your Road King has one camshaft. There are four cam lobes on it.
Intake, Exhaust, Intake, Exhaust.

If you had the camshaft in your hand, and had the gear end facing you, look down the camshaft. You will see those egg shaped cam lobes. You will notice that No.1 cylinder Intake lobe is facing to the left.
No.1 Exhaust is facing to the right.

If you put a degree wheel on the gear end of the camshaft, and had the No.1 Exhaust lobe ramp nose facing straight up, you would see that it's about 110 degrees, before the Intake lobe ramp at .050 lift, comes into play. (The roller, of your roller lifter has raised the Exhaust valve up .050 inch) There is about 55 degrees before the Exhaust valve hasn't quite shut.
This is okay for normal running. Introduce a vacuum leak, and the surge of extra cold air, makes it pop.

Solution? I suggest checking to see if the clamps on those rubber sleeves are loose. You can also spray WD-40 towards the ends of each rubber sleeve, when the engine is idling, and see if it speeds up. Means, one or more, of those rubber sleeves has deteriorated.

SOURCE: 1999 road king wont start

Its your fuel pump if you can't hear it. And its inside your tank. Not a hard fix if you have a book that tells you how to remove it. Alot of procedures to follow to get it right. And yes it does work off a relay.

SOURCE: Oil change directions, 2003 Road King

The drain plug is on the left side of the oil reservoir pointing towards the front of the bike. The motor should be warm when you dump the oil and the o-ring should be replaced as an extra precaution (don't want to waste that new oil if you have a drip). When replacing the oil filter use a piece of tin foil to divert the oil to your waste pan.

SOURCE: My 2000 road king fuel injection starts right up

this could be a couple of different things first thing is to make sure your fuel pump pressures up the system,turn on ignition and listen for your fuel pump to come on,second is to your ignition on and off at least two or three more times this will reset your idle air contol.(make sure you are not on the throttle when you shut the bike off) If this does not clear up the problem you could have a bad senser or loose connection. good luck

I have a 95 Road King that isn't running right, it


Backfiring out of the exhaust is usually an ignition problem. Unburned fuel is getting into the exhaust system because it's not being ignited in the cylinder. When the engine fires on that cylinder again, it ignites the raw fuel in the exhaust causing the pop that people call a backfire. I'd investigate the ignition system. Connect a timing light to each of the spark plug wires if it has a single fire ignition or either of them if the ignition system is the stock dual fire. Start the engine and watch the timing light to tell if the engine is missing as the light will miss a flash.

Good Luck

2000 harley road king will not start,new battery,drained and refill fuel tank,engine light comes on for 4 seconds and hear fuel pump run, cranks over good but no start,has not run for 2 years.


Hi, i would work from here. Check the spark plugs, the plug wires, and the coil. Those hardly go bad, so it's possible that something is not allowing the coil to fire.

Sounds like your battery is shot. Put a new battery in and try, with the new battery in and it works ok for awhile and then starts repeating the same problem, it will be in your charging system.

The relay contacts get carbon (or burn away) on them from arching and cause a high resistance contact ,thus the dim and not working tach ,lights. Check your grounds, and connections for shorts.
