Hi, Anonymous you need to locate the fuel flow origin first to isolate the problem area otherwise the usual suspects are:
1. Fuel tank empty.
2. Fuel cap or fuel tank not venting properly.
3. Fuel filter clogged with rust or dirt.
4. Fuel valve not in the on or reserve position.
5. Vacuum line to fuel valve cracked, broken, pinched, or missing.
6. Fuel valve/petcock clogged or diaphragm cracked, cut or torn.
7. Fuel line from the fuel valve to the carburetor or fuel pump clogged, cracked, pinched, bent, broken, or missing.
8. Fuel pump not working.
9. Fuel line touching cylinder or head causing fuel to boil and vapor lock, repair by rerouting and wrapping line with convoluted tubing.
10. Carburetor inlet clogged.

SOURCE: 2001 raptor cabs not getting gas

Ihad this problem, I let gas sit in the motorcyle over winter. Bad mistake,The whole carb needs cleaned. I took my carb to the yamaha shop and they charged me $146.00 to fix it. Or you can take the jets and needle seat out and soak it in carb cleaner for a couple of days. Yamaha soak the carb in carb cleaner for 2 or 3 days, remember to remove any plastic, gaskets, rubber.

SOURCE: gas flowing out the bottom of carb....

that's your overflow. your float needle is either dirty or your float height needs to be adjusted.

SOURCE: ran out of gas then problem started gas leaks

You will need to remove and clean the carb. When you run one out of fuel it allows all the trash in the tank to go into the carb. The fuel leaking from the overflow is trash in the float needle and needs to be cleaned.

SOURCE: my klx 400 stock carb

check and clean the carb, there must be a dirt or an small object blocking the intake line of carb causing to malfunction the fuel floater. the floater acts like a control switch when the fuel reservoiris already full the floater floats causing to shut of the fuel.

2004 Kawasaki KX 125 quit running


Hey Steve
Put a new spark plug in first...
... Sounds more like a fuel delivery issue... (the jests are in the carb and are considered one item). IF THE ENGINE HAS BEEN MODIFIED - FIND A REAL PRO THAT KNOWS HOW TO JET AN ENGINE - I CANNOT STRESS THIS ENOUGH - THIS IS not FOR AMATEURS!!
Make sure you have fuel flowing to the carb..(turn the gas off at the petcock - remove the gas line and then turn the gas on -- if its flows quickly and a full stream - turn the gas off, reconnect the gas line. Now, on to the carburetor... IF you are a great mechanic, you can clean and set the carb..IF NOT - take it to a qualified pro!! After the carb is cleaned and set.. it should run great...
Please reply to me when you are done with these steps..

1999 KX 125 The bike has compression and spark, the carb seems to be flowing fuel but it won"t fire and seems to be emptying the cylinder we've put fuel directly into the cylinder enough to fire...


Check your fuel filter, sounds like it maybe clogged or needs replaced, can use a generic gas filter to fix or troubleshoot your problem. Rick
