Hi, Phillip, it should be noted that the reasons your check engine light or CEL stays on constantly or flashes and your bike will or will not start and may turnover or not, these conditions will vary from bike to bike depending on the year, make, and model and you should always refer to your owners/service manual for proper diagnostic procedures. It should also be noted that any type of prior work done to the bike or an abnormal event occurrence IE: adding accessories, electrical curiosity or adventures, laying the bike down or crashes, rainstorms or bike washings just before CEL light issues started can be significant hints or aids into tracking down the gremlin, also for 2003 and older models carry the appropriate jumper wire to access fault codes and reduce the risk of being stranded or towed also keep in mind that your CEL comes to life if anything, and I do mean anything isn't 100% with the ECM like parameter spikes. This means that you could be staring at a major repair, or your speedometer sensor is contaminated and needs to be cleaned.
And the usual suspects are:
1. Severely discharged or a damaged battery check the 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, you 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. Faulty charging system.
3. Faulty system sensor some models have up to 40 sensors
4. Faulty safety switches: run/off, ignition, clutch lever, neutral, side stand, tip over, fuel, and or their connections.
5. The engine got wet where it didn't like to get wet.
6. Faulty ignition circuit spark plugs, coils, cables etc.
7. Broken wire or worn insulation exposing wire to a ground situation especially inside wire harness at tight bends around fairing brackets, under dash panels, under fuel tanks over cylinder heads etc. Many harnesses are open on the ends that will allow water to enter and accumulate at v-bends.
Dielectric grease and contact cleaner are your best friends for wire/cable/harness connectors, look for corroded, broken, or loose pins/sockets. Run speedometer diagnostics and check for generated fault codes.

Hi, Kevin 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.

Hi, Anonymous due to the magnitude of yesterday's solar flare my night and x-ray vision optical devices have become inoperable so you will have to be my eyes, to find the source of your oil leak, start at the point where you see oil and trace its path going up and forward, if there is too much oil present then buy a spray can of engine degreaser apply it to the affected area then rinse off with a pressure wand or garden hose, use compressed air to blow off excess water or just let it drip dry, take your bike for a 5 mile ride and check for the leaks.

Hi, Tom it should be noted that in order to "PROPERLY" diagnosis any electric starter issue it is "IMPERATIVE" that you begin with a fully charged battery 12.5 volts or better and be able to pass a proper load test, and the usual suspects are:
1. Battery terminals have loose or corroded connections.
2. Battery cables faulty due corroded or broken internal wiring at the cable connector especially the "NEGATIVE" cable which needs to be checked at "BOTH" ends.
3. Battery voltage, 12.5 volts or better,to the main circuit breaker to the ignition switch to the security/ignition fuse to the TSM/TSSM module to the engine stop/run switch to the starter button to the starter relay to the green wire that connects to the starter solenoid has dropped more than 1/2 volt.
4. With a voltmeter connected to the battery, the ignition switch in the on position, the kill switch in the run position, the starter button depressed, starter engagement should not bring voltage below 8-9 volts.
If a lower voltage is produced a proper battery load test should be performed with a load tester to validate battery integrity or battery replacement.
5. Faulty starter relay, check continuity.
6. Faulty starter solenoid, check contact plate and shoes for excessive electrical erosion/etching, refurbish as necessary or invert contact plate and use the virgin backside. Check contact shoes for being loose. Replace solenoid if the negative function is still a final outcome.
7. Faulty starter, bench test starter with a 12-volt battery if negative function check, decontaminate and undercut armature commutator segments as necessary, check segments with an ohmmeter probe each one and the segment next to it for shorts. Have the armature tested with a growler and field coils, and brush plate with an ohm-meter for opens, shorts or grounds. Replace brushes if less than .438" It is generally cheaper to overhaul/refurbish a starter motor than buy a new one.
