Hi, Anonymous and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. 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.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.

SOURCE: Trouble starting my 2003 TTR 225

how old is the gas it may have a lot of water or junk in it.drain the bowl on the carb and drain the fuel out of the tank, check the petcock screen inside the gas tank. also i would not spray start fluid into the plug hole, it could blow a hole in the top of your piston,spray a little right into your air cleaner or carb.good luck

SOURCE: while riding my yz 125 it just died and won,t kick up again

  • If a hole in the piston then install new piston and rings. Next, clean the carbon off the head and install a new head gasket.
  • If cylinder wall is scared the piston has seized up. Pull the cylinder off and take it to the dealer. Have them bore the cylinder and return it along with a new oversize piston and rings.
  • While at the parts counter, get a new stock spark plug and a supply of Yamalube Two Stroke Motor Oil. You need to add 4 ounces per gallon when filling up. This will be a 32/1 gas to oil ratio. NEVER ride the bike without at least the needed 32/1 mix.
Please rate the solution as a "FixYa" if able. Thanks!

SOURCE: why does my ttr 125 not start then backfires?

Your bike has a diaphragm on the carb. Every time you twist the throttle a shot of gas goes into the cylinder. Chances are you are flooding the engine by twisting the throttle too often. Flooding can create a backfire. Start with a clean dry plug. Twist the throttle once then leave it alone for about six kicks. Repeat the process if needed.

SOURCE: Yamaha TTR 125 L won't idle

i cleaned the carb on the bike and put it back together and now it is as if the float is stuck open and is just dumping gas out of the carb all over the ground.

07 ttr 125 cranks but will not start right up when it does it will not take gas it dies and you have to turn key off and back on before it will start back it will idle for a few seconds and die again over...


I have two ttr 125's and my son has another, all 05's but i ran into this with a friends 02 as well. All ttr 125's are cold blooded bikes to say the least. the cold starting procedure that works is to first lean the bike over to the left till it dribbles a little gas on the floor. hit the electric start for a few seconds only, wait 20 to 30 seconds and do it again. holding the starter button down and cranking will do nothing but flood the bike out. short busts only, dont give it any gas ever, this will also do nothing. first it will start for a brief moment then die, hit the button for about 3 to 4 revelutions and wait, the next time it will start again, most likely only for a few seconds again, repeat this and each time it will run a little longer till it keeps running on it own. the best way to get your ttr to start easier is to cut the top of the airbox off, this will give the bike more power (youll see why when you look at the tiny opening) and allow you to spray starting fluid under the back of the seat right into the airbox. it makes starting a cold bike 5 times faster. usually only 2 repeats of the starting procedure.

Okay so I have a 2003 Yamaha TTR-125 dirtbike, it is NOT electric start, it is kick-start. All of the plastics were replaced so I do not have the original stickers on it with the model, therefore I forgot...


There is a frame number stamped on the frame neck. If you call a dealer they can look up the year and model using an ID microfiche. Next to the stamped frame number there should be a riveted plate with the VIN number on it . If this plate is still on your frame it also has the model number and the model year of the motorcycle clearly printed on it. All Yamaha dealers have the ability to ID your machine using the Vehicle Identification Number.

Take to long to start.. takes almost ten minutes of kick starting... electric starter wont turn over to start bike yamaha ttr 125


The TTR-125 Carburetor's Run Lean by design. Mine had the same issues till I found a post on Thumpertalk.com on Carb and air box Mod. This is a good starting point on gets; 110 and 112.5 main and 17.5 pilot. But you must check spark plug coloring to make sure the jetting is correct. Check spark plug after the bike has been ridden for a wile. I also took out the stock baffle and replaced it with exhaust tip and now it fires up after a few kicks and worms up in a few minutes.
