how do i change my engine bearings and piston rings myself?
because my engine sounds really rough like its going 2 blow up.
its a 50cc x race

id check other things before you get to the engine , it could something else loose like the variator or the stator,

50cc engines pretty simple to do , but youll need new gaskets , gasket compound ,torque wrench if your gonn strip it

and make notes and label pipes , etc to make rebuilt easier

you will also need bearing remover tool (£10)
and alot of patience

pistone rings can be done easily by sliding off the cylinder head , again new gaskets required
