Motorcycles - Answered Questions & Fixed Issues


Hi, Chuck 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, Anonymous 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.

Hi, Sieker1x98076 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, Sieker1x98076 before testing any electrical component in the Starter 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. Depending on battery voltage starter relays and starter solenoids can make the same noise when you hit the starter button. You can easily determine which one is at fault by two simple tests:
STARTER RELAY- place your thumb and index finger on the starter relay and press the starter button, if you feel the click then the relay is faulty and needs to be replaced.
STARTER SOLENOID- bridge the positive and negative poles of the solenoid with a small screwdriver if you get a loud clunk then the solenoid needs to be rebuilt or replaced as necessary. If the engine turns over then replace the starter relay.
A motorcycle starter relay is an electronic mechanical switch that has a small coil winding around a piece of metal that requires low amperage and thin wires to be activated. When you turn on your ignition switch power 12 volts is sent to the relay coil which in turn becomes a magnetic contact point that pulls a spring-loaded contact point to itself completing an electrical circuit that allows more amperage necessary to be accessed by the starter solenoid which in turn acts in the same way as the relay but on a larger scale with its stronger heavier contacts making available the necessary amperage to turn the starter motor. If your battery has low voltage it, in turn, makes the magnetic contact point weak in trying to pull its counterpart to make a connection. These relays are usually encased in a plastic housing that is sealed, depending on the quality of the product. When activated they will produce a small amount of heat to their metal components which in turn can create the perfect environment for condensation to form depending on weather conditions and how careless you may be with a water hose or sprayer while washing your bike. After a period of time, several months to several years depending on the circumstances this condensation is the starter button for electrolysis and the slow build-up of corrosion which ends by preventing the magnetic contacts in making a solid connection and alerts you to this situation with the customary greeting "CLICK or BUZZ" if you get a single loud "CLUNK" then the starter solenoid is at fault and needs to be rebuilt or replaced as necessary. The relay is inexpensive and needs to be replaced however in a pinch they can be forcibly opened cleaned and resealed with silicone. In a nutshell, motorcycle starter relays take in low amperage and send out higher amperage when activated and for curious minds, the voltage remains constant at whatever your battery reads at the time.

1970 Triumph T... | Answered 6 hours ago | 27 views


Hi, Anonymous you need to make sure you have no intake leaks by spraying some Brake Kleen, Contact Cleaner, Starting Fluid, etc. around the intake manifold and seals, if the RPM's go up or down significantly then you have a leak that needs to be fixed before you can continue with the carburetor adjustment.
The engine should be at operating temperature with the choke off to set the idle between 950-1050 rpm. Turn the idle skrew clockwise to increase the idle speed and counterclockwise to decrease the idle speed. If you have access to your air-fuel mixture skrew you may turn it as well, if not there is a video below on how to gain access, make sure you start with clean or new spark plugs. Gently turn the air-fuel mixture skrew clockwise until it starts to bottom out "STOP" do not over tighten as it will damage the taper on the end, now back the skrew out 1-1/2 full turns to establish a starting point start the engine and check the idle rpm's and turn the idle skrew accordingly for 950-1050 rpm if necessary, turn the air-fuel mixture skrew 1/4 turn at a time and let the engine settle for about 10 seconds, turn the skrew clockwise for a leaner mixture and counterclockwise for a richer mixture, you are seeking the highest rpm your air-fuel mixture skrew can acquire without going past 3 full turns from the bottom then resetting the idle skrew back down to 950-1050 rpm If you can not detect any rpm change and can not stall the engine by turning the air-fuel mixture skrew all the way in then your pilot/low-speed jet is too big and needs to be replaced with the next size smaller. Final adjustment should be made with a clean air filter mounted to the carburetor.
