150cc scooter engine shuts off when the rear wheel touches the ground ?

MICHAEL MOKHTAR BESHARA MIKHAIL /

didi you find out what is the problem was ?

I have the same problem with a GY6 scooter : the pressure is good : when it touches the ground it shuts off .. the piston and rings are new , the cylinder gasket is manualy made in cars gaskets maker workshop it is made of klingrit 1.2mm thickness mixed with metal , because I could not find the original cylinder head gasket which has two rubber paint on it and not totaly metalic ... what happens is that : it works for one month very good , but the valves cover vent is pushing oil out to the tube which is going to the air filter ... then after one month it started to get black smoke and shuts off when the rear wheel touches the ground or press brake lever and make black smoke from the muffler , I do not know how the oil goes to there to the piston ??? no problem with the pressure and it works at idle on stand, as why the valve cover vent brings oil out ??? I have seen many people are suffering of the same problem but no one could tell where is the problem ??

1-when i go to adjust timing chain big hole and two small holes on the sides : ( I noted that the drive chain is a little streetched so one of the side holes is a little advanced of the other side hole , there is no way to adjust better than it : so I had to accept this result .

who can help ??? everything is new and professionaly installed as I am a mechanic but this problem is new for me ..

Sounds like a scooter issue maybe you should try a scooter form instead of a vintage moped form

so strange answer : maybe you did not read what I have written ... I am using 150cc GY6 Scooter model 2013 it has run only 10000km only

YOUR VEHICLE IS INDEED A SCOOTER - THIS IS A NORTH AMERICAN BASESMOPED GROUP. IN NORTH AMERICA MOPEDS ARE ONLY THE TWO STROKE PEDAL START VINTAGE TYPE CYCLES. You need to find a scooter group that knows more about the GY6 4 stroke to get some goodly suggestions.
