Hi, I would like to know if anybody out there knows how I can up-grade a 49cc 2003 geely Chinese scooter to get more power without changing out the engine. I was told that it my be possible to change out the piston and head, if that is truth I need to know the size and the name. Thanks for any help anyone can give me

You will have to put in a bigger main jet in the carb and at least a free flow filter to get something from any BBK. After that you may need a free flow exhaust it all depends on the current exhaust that is on there now. Does the scoot have a CVT or is it chain driven.

Hi alleyoop, I want to thank very much for the help and information you are giving me, to your question it is a chain driving in a close oil case. Thank you again

Ok found your motor and it has a CVT belt drive not a chain drive. So your cvt works like this:

Take a picture of the it I think your looking at the wrong thing. If your looking on the right side by the muffler your looking at the oil pump chain which is emerged in oil. I am talking about what is ON the LEFT side the side you get on and where you put the sidestand down.
