New member! Help me tell what cc my zongshen motor is???????

[Ironmike]

Thx for replies. How important is it to clean the centrifugal filter? I ask because previous owner had to extend the kick start shaft by to clear the frame to make it functional. The shaft is welded along with the kick start lever. I ran the motor very briefly with valve cover off and oil is pumping to the top end nicely. Is this an actual screen? Someone plz explain what it does? Thx
