SOURCE: fuel pump?

the fuel pump for your 2000 fuel injected road king is located in the fuel tank. you will have to remove the speedometer housing, by first removing the seat, then remove the one small screw near the seat that holds the speedometer housing in place, also remove the small screw at the front of the speedometer housing and lift the housing off the tank and disconnect the wiring that goes to the back of the speedometer. there is a large oval shaped gold in appearance plate on top of the fuel tank. this plate is what the fuel pump is mounted 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: setting hot idle for 2000 harley davidson

Idle speed on a fuel injected bike must me set by the dealer if it's still stock. I think you can set it yourself in you have a Power Commander on the bike but I don't know how to work with that unit.

SOURCE: Harley spits and sputters.

Unless an aftermarket device has been installed on your bike, you must take it to a dealer to get the fuel map reworked.

SOURCE: 2002 Harley Davidson Electra Glide FLHTPI loses all electrical.

Professeur D is another of the people who just can't say "I don't know" or just be quiet. His comments are worthless. You don't say what the bike model or year is, but I bet it's a newer bike. I have an '02 FLHTCU with the engine juiced up a little and the rear cylinder really runs hot. The circuit breaker is located right over the rear cylinder, and since I have an oil temp gage I can see that when the temp hits 230 the breaker is going to open and shut all electrical off. I've changed breakers many times and the problem is still there and the dealers don't know what to do. I've been told by another rider that I should replace the circuit breaker with a fuse which will not be affected by temp. I'm going to look into that!

Fast idle only when motor warms up


Hi Anonymous, remove air cleaner and backing plate, spray some starting fluid or Brake Kleen at intake manifold to head area and intake manifold to carburator area when engine is cold. If RPMS increase then you have an intake leak and repair as necessary. If you have a carburator your idle adjusting screw is in too far or your air fuel mixture is too lean or your fast idle cam on choke could be faulty. If you are injected please visit website below:

I have 1998 FLHTPI when i slow down at to stop engine light comes on and bike shuts off cold idle is fine when this happens rpms drop below 1000


It sounds as if the idle system is blocked or restricted. If the fueling is injection then you need to get the bike on a diagnostic machine and check the fuel map and the fueling sensors. If it is Carbs- then you need to clean the carbs, the idle jets are very small and block easily over time. I hope this helps. Or you could just keep the revs up along with the front wheel, and save rubber(he he)

What does it mean when riding an ultra classic motorcycle when it gets hot going down the road it shuts off


Sounds like a main circuit breaker problem. There was a service bulletin for a breaker upgrade.

Harley-Davidson Service Bulletin M-1151: Main Circuit Breaker Replacement~Purpose: As recently advised in ML-390, Harley-Davidson has determined that a defect exists on certain 2001-2003 FL Touring and Police model motorcycles. These motorcycles have a condition whereby the 40 amp main circuit breaker could open due to reasons other than for which it was designed, causing an unexpected interruption of all electrical power. This condition could cause a “quit while riding” situation, which could occur without warning and lead to a crash, thereby presenting a risk of death or injury to the rider.

This Harley-Davidson safety recal (code 0113) affected to the following motorcycle: Certain 2001-2003 FL Touring and Police model motorcycles, including FLHTCI, FLHTCUI, FLTRI, FLTRSEI-2, FLHPI, FLHPEI and FLHTPI, assembled/shipped from the York, Pennsylvania assembly plant between May, 2000 and September, 2003.

How to slow fast idle in heritage softail


Sorry but you have to take it to a dealer or someone with a box that can adjust the idle speed. Your fuel injected bike is just like your car, there isn't much can as an owner can do to them anymore. It's been headed that way since 1999. The days of fixing your own motorcycle are slipping away quickly. That's why I'm keeping my old bikes. I can still work on them.

Good Luck

1998 roadking idles to fast after it warms up.


Is it fuel injected or carbureted? If the bike is fuel injected it will idle fast until the engine warms up...if it continues to idle fast after about 10-15 seconds it could have a faulty sensor.

If carbureted, after you push the choke in does it still idle fast? If so, there is an idle adjust screw on the top of the carburetor just behind the air cleaner.

Do you have a tach on the bike? If you do, then the normal warmed-up idle should be 1000rpm.
