Yamaha Teos 125 will not start

I have a yamaha teos 125 scooter... it was working fine but now it will not start. the engine turns over but wont kick in... i have checked the spark plug and all seems to be ok, is there anything else i should be looking at? could it be because water has got in somewhere? i was also wondering if the teos has a kill-switch that i could have accidentally pressed? if so where would it be???

Hi, Emily_irwin and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the enrichner.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
10. Carburetor float stuck.
11. Fuel injectors clogged.
12. Fuel injectors stuck open.
13. 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 cursory 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.
14. 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.
15. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
16. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections loose, or connected to the wrong cylinders.
17. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
18. Faulty neutral, clutch lever, or kickstand safety switch.
19. Faulty fuel pump or fuse or relay.
20. A stuck bent or burnt valve.
21. Tilt sensor needs a reset.
22. Security system not disarming alarm needs a reset.
23. Check for engine trouble codes.

SOURCE: bike wont start

Hi,

Initially, pls check/verify:

  • left ignition coil goes to #1 & #4 plugs while right ign coil supplies 2 & 3;
  • presence of spark on each and all of the plugs;
  • temporarily remove the air cleaner/filter box/assembly and cover each crb opening with the palm of your hand while cranking. presence of gas would be noted with fuel on your palm;
  • engine flooded. remove, clean, dry/replace plugs.
Incidentally, if no spark on plugs, check connectors to CDI, or starting with the clutch lever pulled.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

SOURCE: no spark

It sounds to me like the repair shop has connected the ignition wire ( the wire going to the + side of the coil ) to the wrong switch terminal. Take a volt ohm meter and connect the ground wire to the negitive ( - ) side of the battery and expose the ignition switch terminals. With the switch in the OFF position check for volatge on all the terminals. Make note of any terminals showing a 12 volt reading. That is probably the feed line from your battery. Turn the switch to the ON or RUN position and check for a terminal other than the one which gave you a reading before. note and mark this terminal. Locate the coil. There are 2 thin ( 18 guage ) wires attached to the coil. One goes to the distributer and the other goes to the ignition switch. Isolate that wire and reattach it to the connection on the ignition switch you marked earlier...
Good luck,

change the coil you may not think it got hot but sometimes a coil can overheat on the inside just enough to break the copper winding. when riding hard slow down for a couple of miles to give everything time to get back to normal temps before shutting it off

SOURCE: yamaha yz125 wont start...

hello there guys, listen a top tip is when the engine's cold tip the bike almost right on its side nearly touching the floof, wait for the petrol to poor out of the carb over flow pipe, this should take a matter of a few seconds, stand the bike back up again and kick and that baby should start right up, if it does then you have a problem with your float, if it still doesn,t then take it to a shop and get them to check it out, hope this helps. regards sam

Yamaha Maxster 125 won't start


Hi, Blingdog777 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 because your battery may have 12.5 volts or more but little or zero amps causing the battery to be faulty and must be replaced, especially "AGM" batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. 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.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand or clutch pull in switch/sensor.
9. Security alarm needs a reset.
10. Starter relay, solenoid, starter have failed or circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. The electric starter is working but starter clutch has failed.
14. Check for engine trouble codes.

I have a Yamaha Teos 125 reg.'04 and the fuel /battery indicator gauge fluctuates from one side to the other when the ignition is switched on. I have disconnected the battery for a short time,but it has...


This is normal and only shows the battery voltage and then swings over to show your fuel tank level so nothing to worry about.This will happen on every turn of the ignition and when switching off it reverts to the battery voltage position so if you cam eover to your bike in the morning for example(with a good battery the day before) the needle would have gone lower before switching to the petrol level indicating a weak battery so it;s only a condition check, as with cars whoi have airbags etc that show all lights then switch them off if all is okay.These are lovely powerfull mopeds and if you look after it and service it it will last many miles trouble free.

Yamaha yz125 wont start...


you should try cleaning your carb i dont know how often you clean your air filter but if you havn't done that you should do it also.after you do that turn the gas on lean it over till gas runs out the over flow and give it choke no gas and try kicking it over.you should be able to just loosen up the clamps on each side of the carb and twist it so you can get to the float bowl,unscrew the four screws and blow it out with a air nossle you can try that before you go through the troubles of taking it off to clean it.
