Question about Yamaha DT 125 R Motorcycles
Hi my dt125r will only run with choke on once i turn it off the bike dies soon after even when warm? any suggestions to problem thanks?
Carb no doubt needs a rebuild. Dirt, debris, is not allowing fuel in. Check fuel lines as well. No need to do a part job. Carb ports easily get clogged

Try adjusting the fuel/air ratio screw on your carb. i would start by turning it 1/4 counter-clockwise to allow more fuel to flow in.

Testimonial: " there is no air screw on this model for some reason just a fixed jet inside the float bowl.Thanks anyway."
where the valves set cold or hot? could make the world of a difference...is there intake leaks? bad floats perhaps....its a problem that will take some time cancelling out problem by problem

The pilot jet circuit is plugged up. Clean the carb. Remove the vacuum valve and keep it away from any spray. Remove the choke, air and throttle screws then spray into every hole you can find. The spray should go in one hole and come out another hole. Pay special attention to the jets. Important > count the number of turns inward to lightly seat the throttle and air screws. This is the number of turns you will need to open the screws after lightly seating them during re-assembly. Please rate my answer. Thanks.
