Question about 2003 Yamaha YZ 125
When i start the bike up it wont idle by itself and will cut out, so try again and again and the bike will fire up so i try to rev it up and it will die,almost like its getting flooded but its not or like its not getting enough gas all the stuff ive tryed just dosnt work ive cleaned out carb clean all the exhaust tipped out old gas cleaned fuel filter and lines.
Remove the throttle stop adjuster and the air screw adjuster and spray carb cleaner in the holes.
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Turn the pilot screw 1/4 turn counter clockwise. Check the float level. Before putting the slide back in the throat of the carb, move the clip on the jet needle one notch lower.Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Adjust the idle speed with the Throttle stop screw. This process should get you back on the road. A “very helpful” rating for this answer? Thanks!
