SOURCE: loss of revs

Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There may be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and 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 idle screw and the air screw on the outside throat of the
carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw 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. This process should get you back on the road.

Please rate this solution. Thanks!

Simple thing you have to check...your carb , and your plug.This prob normally come when your bike is seldomly used. gas perished in a month and affect the condition of our bike.try to fill a gallon of petrol. to check if the cause is from the perished petrol.

Clean the carburetor. Pay special attention to the jets inside the float bowl area. Remove the throttle and air screws and spray cleaner into the holes and every other hole in the body of the carb. Remount the carb then screw the throttle and air screws inward until they LIGHTLY seat. Now open each of them one and one half turns. If the bike still wants to speed up the idle on its' own, the seals and rubber fittings between the carb and the cylinder are not sealing out the outside air. New seals etc., are needed.

SOURCE: hi,50 cc aerox yamaha,will start

Chances are the battery will need to be replaced. It went dead for a reason and if the reason wasn't because the key was left on, then old age, ( over one and one half years old or more ), or an internal short in the battery is what has killed it. Re-clean the carb and pay special attention to the main jet. The factory setting is one and one-half turns open from a lightly seated position. Look in the end of the carb. Does the slide lift when the throttle is twisted? Put the jet needle positioning clip in the middle notch of the jet needle. Clean the air filter. Please rate my answer. Thanks! tombones49_38.gif
