I have a problem with carburetor of the MX1 125 cc. I cleaned it but it still doesn't work well, can anybody help me find a way on how to clean the carburetor of the MX1 125 cc?

What do you mean by, "doesn't work well" bujariz?

Are you sure the carb is the problem? Apart from washing out, and blowing air through the jets, nothing much else to do.

I clean mine with WD40.

and check up all the jets.
Maybe someone has mounted bigger ones, or has 'tuned' the carb with a drill

well with the words "doesn't work well" I mean: the motor turns on good but don't keep the gas, I have to give more gas in order to stay turned on, and when I give more more gas the motor doesn't have a good gas sound. The problem is with the carburetor for sure, because I have had this problem 2 years ago.
Thank you very much for your response!

Well, if you have cleaned the carb and you are sure it IS clean, check the following-

Assuming the bike was at one time working with this carb.

Is fuel coming out of the fuel line into the carb at a constant flow? If the fuel vent in the tank is blocked it will cause a vacuum and stop the flow.

Is there an air leak between the carb and head, or try fresh fuel. The fuel may be contaminated with water, rust etc... may also be worth fitting a new spark plug, the old one may be breaking down.

Have fun

Just a thought, It may benefit from a de-coke. The exhaust port may be blocked with carbon deposits. If you don't ride a 2-stroke like you want to 'kill it' then they can foul up.

Let us know how you get on!!

Well I think I have cleaned the carb but I will try to clean it again. The fuel is flowing to the carb constantly. I will try to turn it on with fresh fuel, the old one could be contaminated with water! And I will change the spark plug too. Thank you very much for your concearn guys .

Hi bujariz!
Water into carburetor can give you this problem!
Check it better!

Thank you very much all. I fixed the problem with the carb, the carb was fullfilled with dirt, I used a spray anti oil and dirt, it opened the holes of the carb. Now it is working perfectly. I found also the service manual and that helped me to open the carb. Thanks again.

Best way for cleaning will be Ultrasound-bath; a lot of runs!! ... but carb should be in parts!!!!!! Do it with hot water with a little bits citric acid!
