My 2001 yamaha 125l ttr having a fuel issue.fuel sqirted in through air intake,bike runs,throtle respondsive,couple seconds only.maybe dismantle carb and blow out.appreciate any insight.thank you.

ALWAYS have a fire extinguisher on hand when working on carburetors. Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains then remove the carburetor from the engine.

Remove the float bowl and soak the entire carb in denatured alcohol for 30 minutes. Now clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the "blue" items on the carb and spray into the screw holes as well. Don't mess with #16 but if you must, be sure to count the number of turns and replace the same number of turns.

Be sure to put all screws back in the same hole they came out of. IMPORTANT > do not tighten #8 and #12 adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. 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.
Please rate this answer. Thanks!

I have three hose line. 1 goes to the fuel tank. 2 is the over flow line what is number thee.
