Question about 2006 Yamaha TTR125LW
I've already cleaned out the carburetor
Posted by Anonymous on
Hi, Anonymous and the usual suspects are:
1. Fuel mixture too rich or enrichner left out too long.
2. Faulty spark plug.
3. Incorrect spark plug for the engine type or service.
4. Piston rings badly worn or broken.
5. Valve guides are badly worn and/or seals worn, crushed or have come off the valve guide and are pumping oil through it.
6. Spark plug cable weak or leaking check for spark jump in the dark.
7. Faulty ignition coil.

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.

Hi and welcome to FixYa,
Since there is spark, then the only other possible missing component would be fuel. Drain the carb by loosening the drain screw. Check draining fuel's quantity and quality. If no draining fuel, then spray starting fluid to the carb air intake. The fuel cutoff valve (petc0ck) is vacuum activated. It would only allow fuel to flow if there is vacuum (i.e. when the engine is running). The irony is the engine will only start/run if there is initial fuel in the carb.
Good luck and thank you for asking FixYa.

Testimonial: "Thanks, Drain screw stripped by previous owner removed carb.bottom drained/refilled STARTED OK NOW /////////////////"
A compression test will tell you your condition. (Throttle wide open while doing that) If that's good, your jetting is too rich, could be the issue.
