Anyone know anything about these Chinese moto toys? I've got a 50cc dirt bike I gatta order parts for. Are all engines on these things considers a gy6? If not how so I identify engine?
Post up a pic of it and ill find you a parts website.
You may be working on it more them ridding it.
The top link Dualstroke posted shows the CRF style engine, you can get them in displacements up to about 180cc if I remember correctly.
The Chinese basically stole Honda's blue prints to make their pit bike engines. You can use OEM Honda parts or just type in "pit bike" before the part you need and compare the pics. I've completely rebuilt my bike this way without any problems.

Here is a picture of a friend and my bike I just got done freshening up. I wish I had a before pic because the thing was completely beat to the point where it wasn't even rideable.
