Harley Davidson FLSTF - FLSTFI Fat Boy - Recent Questions, Troubleshooting & Support

First check for spark by using a known good plug and laying it on cylinder head while cranking. Leave the original plugs in. Do NOT remove them for this test. If no spark then either crankshaft position sensor or the ECU or the coil or system relay or fuses or wiring is faulty. If you do not have good electrical knowledge to check these out, bring it to a dealer. If good spark, then fuel must be the problem. Check to see if fuel pump runs for a few seconds when turning bike on. You shoud hear the pump running for a few seconds then stop. If the pump does not run, check system relay and fuel pump fuses. Note - the pump will only run once when turned on/off every few seconds. Bike needs to be off for at least ten seconds for next pump cycle. Check to see if faults codes are stored in ECU memory as these may lead you to the cause.

Undo the nut. Clean both sides of the connector tags with a new steel wire brush. Smear contacts with Vaseline or dielectric grease. Re-fit and bolt back up. https://www.ebay.com/b/Starter-Motors-Relays-for-2005-Harley-Davidson-Fatboy/177959/bn_87762209 ..

Hi, Anonymous your instrument gauges and lights can alert you to most electrical and engine issues they can not warn you about failed engine gaskets or seals so your engine has to resort to old fashion alert methods of colored "SMOKE SIGNALS" here is a breakdown of their meaning: 1. COLORLESS OR SLIGHTLY BLUE SMOKE on start-up means your air/fuel mixture is the right composition and everything is well burnt in your combustion chamber. 2. BLUE SMOKE on startup is usually caused by failed valve seals dripping oil into the combustion chamber when the engine is not running. 3. YELLOW OR BROWNISH SMOKE at start-up means your air/fuel mixture is too lean. Too lean means that there is low fuel but high air mixture in your combustion chamber. 4. WHITE SMOKE on startup may be caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers. Smoke while riding is usually caused by worn out or damaged valves, seals, guides, pistons, rings, or cylinder walls. 5. BLACK SMOKE on startup is usually caused by too much fuel in the combustion chamber this can be due to air/fuel mixture adjustment too rich, accelerator pump improperly adjusted, faulty choke or not in the off position, air filter dirty and clogged, faulty carburetor float needle and seat, pilot jet too large, fuel injectors leaking, smoke while riding is usually caused by the main jet being too large or a damaged carburetor. It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.

Hi, Anonymous if you ask 10 different riders you will get 10 different answers. All oil is certified by the Oil Gods to perform under specific conditions for specific applications and any oil is better than no oil and if you're in a bind diesel oil works just fine. If your engine is air-cooled never run automotive oil because normal motorcycle cylinder head temperatures run much hotter than water-cooled cylinder heads, make sure the oil is designed for motorcycles. Your owners manual recommends a specific type of oil that is designed to lubricate the engine parts to withstand the normal driving conditions the motorcycle was intended to be used for, end of the story. Now for an analogy, your cars owners manual recommends using 87 octane fuel to power your engine for maximum performance and it does a wonderful job of achieving that goal. But you say 92 octane is better because it has a higher number and is more expensive, well guess what your car will not run any better and there are no long or short term benefits from running a higher octane fuel bottom line your car doesn't need it. Same thing with oil sure they make lubricants that can withstand the temperature of molten lava which you would need if you were planning to drive into an active volcano, don't waste your time and money on snake oil just use what your bike needs and your manufacturer recommends and nothing more. The oil weight grade is for ambient temperatures you expect to drive in between oil changes 20w50 covers 80% of all driving temperature conditions if you're looking for a better oil that works in all temperature conditions, buy a Synthetic in the same grade from a reputable oil manufacturer I recommend AMSOIL just because they were the pioneers in synthetics and their load test numbers for wear put them in a class all by themselves and you can go longer and further in between oil changes. It's a little hard to find in stores but easily available online otherwise Harley Syn 3 is my second choice.
