    Yh you got it mate , and it definitely sounds like piston rings to me because you got more compression when you put oil in the bore giving it more temporary compression , oh and whats your msn addy mate i got one add but the address is weird

    Posted my email on your profile, also yeah i will get the new piston very soon yeah because when i put the new gaskets i forgot to oil it so i took all off and put 2T oil and much more compression now if i put my finger covering the spark whole my finger will pop out.

    that pistons beyond fucked!

    is this bike a 2 or 4 stroke?

    edit: shit i just realised i asked you that on the first page


    get a new piston in there, but check the ring gap first. if the gaps too big, the bores fucked.

    thinking about it, your main bearings might alao be knackered which causes that hideous grinding sound when you turn it over

    Hey guys i am back, i had problems with the piston being wrong sized that wouldn't fit on the small end bearing so i had to send it back they took a while to send the new piston back, so last week the piston arrived and i fit the piston and all good, also i ordered a new fuel vacuum where the lines goes to the carburetor, today i cleaned the carburetor so i tried starting the moped and did not start, looks like it has air compression as my finger pops, and i charged my battery over night and still not the problem. The petrol are reaching the carburetor as i cleaned it i seen there was petrol there. i have also checked the spark plug and is okay, i also tried by putting some petrol into the spark plug hole to see if it started but still didn't anyone has any idea?
    I have checked all wires and they are all connected as they should be.


    I have just checked the spark plug and the spark plug fails to spark sometimes when i am doing electric start and makes that noise from the video you can see, but i am trying to do kick start it will start sparking the blue sparkles. ( Tomorrow i will pick a spark plug and see if makes any change. )

    when you installed the piston did you make sure the arrow is facing the exhaust port

    right ok , so you have fuel , you have compression , and some spark but might not be enough , so could be a coil or cdi fault
