Hi, Felicia and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. A failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, stator, magneto, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Faulty or corroded kill switch.
11. Accelerator pump damaged or not working.
12. Water or dirt in the fuel system, carburetor or filter.
13. Restricted, blocked or kinked fuel line.
14. Fuel tank empty.
15. The gas cap is not venting properly or fuel tank venting system blocked, loosen the gas cap and go for a test ride.
16. A failed fuel pump, pressure regulator and or fuel injectors.
17. Vacuum line from the intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
18. Needle and seat stuck closed in the float bowl.
19. Petcock clogged or damaged.
20. Lean angle switch is faulty or needs adjustment.
21. Catastrophic engine failure, perform a compression test.

Your bike's timing can only be adjusted through an interface to your ECM like the Screamin Eagle Race Tuner. Have you made any changes to the exhaust or intake? Have you added and aftermarket item like a Power Commander? changes in these areas could account for the problem you are having. hope this helps.

SOURCE: 2001 Harley Davidson FLHRCI Road King Classic how to adjust the throttle cables

Hi, Eddie throttle cable adjustment is fairly simple but before making any adjustments you should disassemble the throttle control housing allowing access to the inner cable for lubrication. I highly recommend "DRY SLIDE" then reassemble the throttle control housing and proceed as follows:
1. Back off the jam nuts on the pull and return cable.
2. Screw the cable adjusters all the way in.
3. Back out the pull cable adjuster enough to open the butterfly plate to maximum horizontal position ie. straight across.
4. Back out the pull cable adjuster until the carburetor piston or slide is all the way up.
5. Lock down the pull cable jam nut.
6. Back out the return/idle cable adjuster until there is 1/8th" free play on the throttle grip while pulling moderately on the return cable.
7. Lock down the return/idle cable jam nut.
8. Snap the throttle several times to ensure integrity.
9. If the bike rpm's are too low and the engine does not idle, adjust throttle stop screw as required.

My harley davidson road king keeps cutting out like its running out of gas or vapor locking any ideas?


I had the same problem on my 06' (Fuel injected). It was the copper filament inside one of the wire going to the injectors. It took 3 visits to the dealer and 4 hours of investigation to find it.

Two things, first what are the tyre pressures for a 2001 Road King FLHRC and The fuel pump is whistling, high pitched, can an additive to the petrol fix this.


Ok, for "one-up riding", tire pressure is 30 psi in both tires. For "two-up riding", increase the rear pressure to 36 psi.

If the fuel pump is whistling, I doubt seriously if any gasoline additive is going to help but I don't guess it would hurt to try it.

Good Luck!

If you have carb, it may need to be adjusted,
