Hi, Anonymous and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the choke.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
10. Carburetor float stuck.
11. Fuel injectors clogged.
12. Fuel injectors stuck open.
13. Quick disconnect check ball stuck.
14. Compression below 75 PSI.
15. A stuck-bent-burnt valve.
16. Improper valve clearance (too tight)
17. 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 cursory 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.
18. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
19. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
20. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections are loose or connected to the wrong cylinders.
21. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
22. Faulty neutral, clutch, kickstand safety switch.
23. Faulty fuel pump or fuse or relay.
24. Faulty or corroded run/stop switch.
25. Tilt sensor needs a reset.
26. Security system not disarming alarm needs a reset.

Hi, Andrew the ignition circuit cut-off system comprising of the side stand switch, clutch switch and neutral switch has the following functions:
a. It prevents starting when the transmission is in gear and the side stand is up, but the clutch lever is not pulled.
b. It prevents starting when the transmission is in gear and the clutch lever is pulled, but the side stand is still down.
c. It cuts the running engine when the transmission is in gear and the side stand is moved down.
Periodically check the operation of the ignition circuit cut-off system according to the following tests.
With the engine turned off:
1. Move the side stand down.
2. Make sure that the engine stop switch is set to "RUN"
3. Turn the key to "ON".
4. Shift the transmission into the neutral position.
5. Push the start switch if the engine does not start the neutral switch may be faulty.
With the engine still running:
6. Move the side stand up.
7. Keep the clutch lever pulled.
8. Shift the transmission into gear.
9. Move the side stand down if the engine does not stall you may have a faulty side stand switch.
After the engine has stalled:
10. Move the side stand up.
11. Keep the clutch lever pulled.
12. Push the start switch if the engine does not start you may have a faulty clutch switch.
This check is most reliable if performed with a warmed-up engine.

It sounds like you have a bad vacuum leak. Check the carb mounting bols to make sure they are tight. Check all of the vacuum hoses for cracks and leaks. If this doesn't turn anything up, you can check for leaks around the carb mounting points by spraying carb cleaner around the base of the carb (If you spray the leak, the engine RPM will go crazy. - this can work on hoses that are hard to get to also)

Replace the clutch cable. Replace, or recharge and test, the battery, it should have about 12.5 volts when fully charged. Then you will most likely need to remove and clean the carbs. Use care in cleaning the jets, do not make the holes any bigger just get the crud out.

Hi, Andy the vast majority of service, parts fiche, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee of $15 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available and some were never printed in English. The Indian and Philippine markets are usually in E-book format only, for these rare occasions I shall look on eBay and find the cheapest one available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. If there is no $ sign after the manual link it is free to download.

Hi, Michael before you can diagnose any electrical component in the Starter Circuit it is "IMPERATIVE" your battery must be fully charged to 12.5 volts or more and be able to pass a proper "LOAD" test because your battery may have a preliminary reading of 12.5 volts but little or zero amperage, the battery is faulty and must be replaced. Your starter motor stays engaged because the solenoid positive plunger contact plate/disc has spot-welded itself to the negative contact shoes usually caused by low battery voltage, faulty starter relay, or button. Your starter motor has two main systems the motor itself and the starter solenoid which transfers high amperage to the motor enabling it to turn over your engine, your issue only involves the starter solenoid and may be repaired without removing the starter in most cases and depending on the model of your Harley may require removing the rear exhaust pipe if it's in the way. The solenoid is the part that has a large copper stud protruding from it that the positive battery cable connects to. Start by disconnecting the battery negative cable and wrapping the cable terminal with any kind of tape so it will not accidentally touch metal and make all electrical circuits hot again, remove the starter solenoid cap, secured with 3 screws 1989 and later or 2 screws 1988 and earlier, with a screwdriver break away the contact plate from the shoes and clean/dress all electrical arc residue. In order to diagnose the starter circuit, you must start with a fully charged battery, 12.5 volts or better and be able to pass a proper load test if necessary. The battery cables and terminals must be clean and tight. The "NEGATIVE" cable is famous for corroding and or breaking inside the harness, check the terminals at both ends. Check your starter relay with a test light for continuity, it could be faulty due to corrosion and sticking in a closed configuration, another claim to fame. Finally, there is the starter solenoid, low battery voltage or faulty battery connections will cause extremely high amperage at the plate and contact shoes and rob the hold in coils of much-needed voltage. In extreme cases, the solenoid plunger plate will literally spot-weld itself to the contact shoes, keeping the circuit closed and thus permanent engagement. Another scenario is unacceptable voltage drop to the starter solenoid from the ignition switch to the starter relay to the starter button, and finally to the solenoid. Remove the green wire from the starter solenoid and hook up the positive lead of your voltmeter to the green wire connector and ground the negative lead. Turn on the ignition switch and depress starter button, the voltage reading should be no more than 1/2 volt less than the battery voltage. If it is more than 1/2 volt you need to backtrack that part of the circuit with your voltmeter until you find the voltage robbing offender. Next, remove the solenoid plunger, dress the plate and the contact shoes of arching residue and make sure the contact shoes are tight and secure. If you have done all of the above, replace the green starter button wire, hook up your voltmeter to the battery and check the voltage drop when you start the engine, anything below 9 volts could indicate a faulty battery and a proper load test should be performed.

Connect an OBDII code reader into the diagnostics to read the fault code!
Fix the fault and then reset the codes!
If the fault is fixed the vehicle will be driveable again!
