Hi, Anonymous it should be noted that the reasons EFI lights constant or flashing, will or will not start, turns over or not conditions varies from 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 or event IE: adding accessories, electrical curiosity/adventures, laying bike down/crashes, rainstorms/bike washings just before EFI light issues started can be significant hints/aids into tracking down the gremlin, also carry the appropriate jumper wire to access fault codes to reduce the risk of being stranded or towed, that being said the usual suspects are:
1. Faulty Fuel Pump, fuse or system relay switch.
2. Battery starting to fail due to old age/damage, perform a load test.
3. Discharged battery, check 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 if necessary.
4. Faulty switches/sensors: run/off, ignition, clutch lever, neutral, side stand, tip over, fuel, and or their connections.
5. 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. For more information about your issue please visit the websites below. Good luck and have a nice day.

Hi, Anonymous if your headlight is not working, only one beam works, keeps burning out, blinking, or is dim the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, then check your head light 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, chaffed, or broken wires in the light circuit.
4. Corroded, broken, or loose pins/sockets in wire connectors.
5. Faulty hi/lo beam switch.
6. Faulty ignition switch.
7. Fuse is good but no continuity on both sides.
8. Faulty wiring between battery positive and headlight bulb socket.
9. Weak charging alternator/generator.
10. Faulty voltage regulator/rectifier ground or overcharging.

take it to a yamaha service center and have them check the voltage output of the charger system
if it chargers more than the 14.5 volts for a 12 volt battery or more than 8 volts for a 6 volt battery , that will explain the causes of rapid battery failure

Everywhere I read is wrong. For Yamaha Cygnus-X 125cc rear wheel removal
It is removed from the right hand side. Do not start dismantling the gear box side !
Remove 5 bolts of exhaust. Careful don't loose exhaust seal where it connects to engine. You may need friend to lean the bike over to access bolts underneath.
2. Remove main 24mm bolt on axle
No need to loosen brake !
3. Remove 3 bolts holding swing arm. That's the big triangular bit.
4. Pull off the swinging arm and on axle is special shaped washer. Note which way it comes off.
5. Pull off the wheel leaving brake shows behind.
