    Unhappy help needed



    hi, my sp150 have serious leaking of petrol when on side stand. Within a day, half a tank of petrol is leaked away. Any idea of this problem? I have went to bike shop, they serviced the carburetor, and also ask me to switch the fuel valve to Off mode when is stationery. I have tried it yesterday and going to monitor further. But i have concern will there be more problem if i constantly need to adjust my fuel valve?

    Where the leak from? check the below
    1) check tank, fuel pipe, joint any problem? such as crack, deteriorate ( unlike, but just check)
    2) leak if from carburetor, mostly the float is not functioning.. service the carb should help, but float spoiled the problem is not gone.
    3) Also the needle that stop the flow need to check in good shape.. again carburetor related, mechanic should know.

    I believe your problem is solved.

    Change fuel valve. Not expensive.

    I went to another motorshop, the uncle suggested me to change the carburetor, which i did. No more petrol leakage though fuel valve is on. But my bike is having tough time kick starting after the change. Even need to attempt choke start. The RPM tend to drop to 1 and die off.

    The fuel leak after the petrol cock means your carb leak or any tubing after the petrol cock.

    Why need to change ENTIRE carb?

    You either replaced the carb gasket or the over flow valve in the carb ,to address the leak from the carb.

    No wonder the moto tiams are doing a 'carrot chopping' business.

    Your bike has more than carb problems. You have a air leak somewhere , which causes your 2T engine to stall and rpm to be erratic.

    Hi All, help needed. Im unable to kickstart my bike. Condition: managed to kickstart the engine once, but engine will die off less than a min though on choke. And unable to kickstart thereafter. Aside, the neutral light is dimmed or black out when i attempt to on the headlight. Is it battery flat or overflow carb?

    like battery flat caused by magnet coil or rectifier.

    prepare call tow truck or get a battery ride bike shop ASAP.
