Harley Davidson Motorcycles - Recent Questions, Troubleshooting & Support


Hi, Lowell and the usual suspects are:
1. Severely discharged or a damaged battery must 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. Faulty 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. Faulty main circuit breaker or ignition switch, check for loose connections and continuity.
5. Faulty system relay or ignition relay, check for continuity.
6. Faulty ignition coil, ignition/electronic module.
7. Faulty 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. Fuel tank empty
11. Fuel tank contaminated with ethanol sludge.
12. Water or dirt in the fuel system, or clogged filter.
13. Quick disconnect check ball stuck.
14. Restricted, blocked or kinked fuel line.
15. Faulty fuel pump.
16. Faulty pressure regulator.
17. Faulty or clogged fuel injectors.
18. Lean angle switch is faulty or needs adjustment.
19. Catastrophic engine failure, perform a compression test.

Hi, Thomas 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 from $7 to $15 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available, 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 view and print.

To adjust the valves on your Ironhead Sportster, first collapse all the pushrod tubes, remove the spark plugs, and get the rear wheel off the ground. Put the transmission in fourth gear. Now, use the rear wheel to turn the engine.

To adjust the valves, bring the front cylinder to Top Dead Center. Use a common plastic drinking straw down in the spark plug hole to make sure the piston is at Top Center. Make sure both tappets for the front cylinder are all the way down. Now, loosen the lock nut slightly and turn the adjuster to make the tappet longer. You want to make it just long enough so that you can't turn it with your fingers. Gradually back down on the tappet until you can turn the pushrod with your fingers. Lock the locknut down when done. Now do the other tappet.

Once you've done the front cylinder, turn the engine using the rear wheel until the rear piston comes to Top Center. Always turn the engine in the normal direction of rotation. Adjust the two tappet the same way as you did the front cylinder tappets.

When finished, put the transmission in neutral, lower the rear wheel, put the plugs back in, and close up the pushrod tubes.

These tappets set to Zero Backlash, none. Therefore this must be done on a completely cold engine. When the engine starts up and as it warms up, the cylinders and head "grow" due to the heat expansion properties of the metal. As they grow, you pick up valve lash and the valves will clatter a bit. This is where the old saying came from, "You can tell it's a Harley from a mile away by the way the engine sounds. You can tell it's an Ironhead from a half mile away from the valve clatter". If you get the valves too tight, when the weather cools down in the winter, you could wind up with a valve standing open just enough to make the bike impossible to start due to low starting compression. It's better to have the valves a bit loose and have them clatter than have them too tight making the engine difficult to start.

Good Luck,
Steve

If the battery was flat, you would have to reset the alarm and immobilizer. It is the immobilizer that is not allowing the bike to start. I know how to do it with a car, but not with a Harley. Check out the link

Hi, Stanley before diagnosing your blown fuse issue, check the bottom of your seat, if its metal and comes in close proximity to the positive battery post you need to take the necessary steps to ensure there is no contact (electrical tape, thick rubber insulation, hammer a dent in the seat bottom etc.) You are going to need a wiring diagram from your service manual, a test light, an ohmmeter and plenty of extra fuses.
If you turn on your ignition switch and immediately blow a fuse you have a hard/dead short and is usually easy to find. With a test light connected to the hot side of the blown fuse holder start stabbing the wire/s that leads away from the fuse holder and towards the ignition switch, you test light will illuminate validating the short. When the test light fails to illuminate you have passed the short and need to back up until the test light illuminates, then look in the immediate area for the short.
If you driving down the road for 30 minutes or 15 miles and blow a fuse you have soft/flying short and may take some time and patience to find.
If the main fuse/circuit breaker constantly blows/trips while riding you probably have a faulty battery terminal connection. Check battery terminals for damage or corrosion, check 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. Any other fuses that constantly keep blowing while riding are usually caused by a loose or corroded ground wire in the circuit, which means you have to check, inspect, test each and everyone with an ohm meter set on a low ohm scale 100 ohms or less . Simply touch one lead to the ground source and the other lead to the battery negative terminal, a reading of zero indicates a clean solid ground. Any reading or infinity indicates a poor ground and needs to be repaired. Poor or weak grounds require excessive additional amperage to complete the circuit which in turn blows the small amperage fuse.

I am not familiar with this model and I don't want to insult your intelligence but are you sure that it has seperate oil for the gearbox from the engine? If it has then I assume you have checked for a sump plug and there isn't one. The absence of a plug would indicate that Harley Davidson probably don't think the oil needs to ever be changed. I have a GM car that has done 215,000 miles and I don't think the gearbox oil has ever been changed (No sump plug). However having said that your machine is a quality bike and you probably want to treat it to an oil change. It should have a level plug or a dipstick to check the level. Plug types require you to remove the plug and top up the oil until oil starts to leak out of the plug to get the right level. If you haven't got a sump / drain plug the only way you are going to drain the old oil is to use a vacuum pump and a hose in from either the filler hole or level plug hole. Vacuum pumps with a reservoir are a useful tool and can be found on eBay.
