How do I identify my engine?

[shuffle831]

I'm running a stock 2011 Taotao ATM50-A1 and I want to find out what kind of engine its using, along with a potential blueprint of the engine for mechanical purposes that will come to fruitation in March. Any ideas and/or help on this?

can you find the numbers on the side of the motor?

I've seen a bar code on the left-hand side of the motor, that's it

Edit: Nevermind, I found it. Its a 1P39QMB engine

You'll see all tags on the engine there.

Congratulations, that puts you with the majority of the 50cc scooters from China, it is also called a GY6, they come in 50cc, 125cc and 150cc versions. The 125 and 150 are a bit different than the 49/50cc motor is.

You will find a lot of after market things available for your scooter.

Why do we see so little of them on scooters?

They are usually sent to countries other than the USA. They are just a little smaller bore than the 150 is. If you go to a English scooter forum you'll see a lot mentioned there about them.
