Motorcycles - Popular Questions, Answers, Tips & Manuals


Hi, Greg love that name if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will not idle unless the choke is full on and run poorly then stall, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition and in the future pour in a bottle of fuel stabilizer and injector cleaner for you FI folks at least 2 times a year and before storage.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or more, any readings in the 11 volt range you need to do a proper "LOAD" test on the battery and replace as necessary, you may have 12.5 volts or better but little or zero amps, any readings in the 10 volt range you have a dead cell and the battery needs to be replaced.
4. Drain and flush fuel tank if it rusty there is a cheap and easy fix. https://www.youtube.com/watch?v=fUYr_7SwGms
5. Remove and inspect your air cleaner paper elements that are not oil soaked can be cleaned with a soft brush and low pressure compressed air, oil-soaked elements must be replaced. Gause mesh and foam elements can be cleaned by soaking them in a container big enough to completely cover them with a solution of 1 gallon of water and 1 oz. of Dawn dishwashing liquid for small and medium size elements, for monster size double the formula and let soak for at least one hour then rinse with warm water shake off excess and let air dry, "WARNING" do not use compressed air as this will embed micro-sized dirt and road grime and destroy the mesh pattern and stretch foam elements out of shape just squeeze it like a sponge and let air dry, use a fan if you're in a hurry. When completely dry spray a very fine mist of air filter oil evenly around the whole element.
6. Remove the carburetors, disassemble and decontaminate with a "CARB DIP" or if you have EFI remove injectors and clean with carb spray and compressed air
7. Check intake manifold and seals for leaks and cracks.
8. Remove fuel valve and filter disassemble and clean as necessary, remove, clean, and inspect fuel and vacuum lines and replace as necessary.
9. Replace spark plugs with new ones and check for spark.

Carb needs to be cleaned. Old gas in the carb sticks the float bowl in the up position. You probably have an electric fuel pump. It will be in the float bowl and may be also stuck. Remove it , heat it with a heat gun ( carefully as you don't want to melt it . ) once heated , tap it with a dead blow hammer sharply but not too hard. Clip two wires into the electrical leads and touch one on a negative post of a battery and the other on the positive and then reverse back and forth until it breaks free or 1 min ... repeat, tap , and repeat until it frees up. Once that's clear you may have to clean the injectors if it doesn't start. Old gas is the worst. It makes varnish which is like glue. Use high test and a good stabilizer if your gonna leave it set for more then 3 weeks.

Hi, Jo-El before testing any electrical component in the Starting Circuit it is "IMPERATIVE" that you have a fully charged battery of 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 type batteries fall into this scenario more so than lead-acid batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Engine Run Switch is "FAULTY" or corroded.
4. Check the 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.
5. Bank angle sensor needs a reset or is faulty.
6. FOB battery low or dead.
7. Faulty ignition switch.
8. Faulty starter button.
9. Faulty kickstand, clutch, neutral safety switch.
10. Security alarm needs a reset.
11. Starter relay, solenoid, starter motor or circuit wiring faulty.
12. Starter armature or field coils have failed.
13. Main fuse or circuit breaker may be blown or faulty.
14. Faulty ignition relay.
15. The electric starter is working but starter clutch has failed.
16. Check for engine trouble codes.

Hi, Anonymous if your headlight is not working, only one beam works, keeps burning out, blinking, dim or surges from bright to dim to bright the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, then check your headlight bulb socket ground wire for a clean tight connection, that being said the usual suspects are:
1. Faulty ground or power supply wire to headlight bulb socket.
2. Worn down solder contacts or loose fit of the bulb base in the socket due to vibration.
3. Worn, chafed, or broken wires in the light circuit.
4. Corroded, broken, or loose pins/sockets in wire connectors.
5. Faulty hi-low beam switch.
6. Faulty ignition switch.
7. Fuse is good but no continuity on both sides.
8. Faulty headlight relay.
9. Faulty wiring between battery positive and headlight bulb socket.
10. Weak charging alternator/generator/lighting coil
11. Faulty voltage regulator/rectifier ground or overcharging.

Hi, Tricia moisture, condensation, rain, or bike washing can make the bike run sluggish, not able to rev, and misfire. Older bikes, engine configuration, and exposed electrical components are at the front of the line for acting up. During the diagnostic procedure spray Electrical Contact Cleaner on corroded wire connectors/pins/sockets etc. and apply a liberal amount of "DIELECTRIC" grease to the mating harness/wire connectors. WD40 works great for eliminating suspect areas in your quest to find the real offending gremlin.
For additional insurance you can spray a High Temp Clear Coat on the most vulnerable areas it will work like Scotch Guard does on fabric. Fabricate a rubber or plastic splash guard to deflect water coming off the front wheel getting to the front cylinder spark plugs. The design should be adequate for its purpose with the least amount of airflow restriction to cool the cylinders. The usual suspects are:
1. Air filter soaked with water.
2. Water in the fuel system gas tank and carburetors.
3. Wet ignition coil packs.
4. Spark plug boots wore out or loose allowing water to enter.
5. Spark plug cables old and cracked check for spark leakage in the dark.
6. Spark plug wells filled up and drain holes clogged.
7. Water in a wire harness that has exposed open ends and have a sharp bend or crimp allowing the liquid to form its own pool of potential threats to chaffed wiring.
8. Sensitive fuel tuners and downloaded ECM remaps may get confused with the abnormal cylinder temperature difference in a V-4 engine configuration.
9. Fuel injected bikes need to have the electrical connectors removed and sprayed with contact cleaner then blown dry and checked for continuity with a test light or multimeter, then treated with Dielectric Grease.
If your bike will not run right or even start after going through the checklist, despair not, letting it sit for a couple of days in a warm environment is like an eviction notice for the Gremlins and then your bike will be back to its old self. You can speed up this process by using forced air to dry out electrical connections.
