Not that kind of China Girl pervert, I'm talking about a motor bicycle LOL.
This is the easy way to install the piston in the cylinder of a china girl.
First, make sure the arrow on the top of the piston is facing forward.
Next, position the rings on the piston so the ring end gaps straddle the lock pins located in the ring lands. The reason for the lock pins is to prevent the rings from rotating during operation, which might allow a ring end to snag on one of the port windows, breaking the ring.
Now, before you can slide the piston into the cylinder, you must compress the rings. A very easy way to accomplish this, is with a plastic duct strap commonly used to connect air conditioning flex ducts. If you can't find duct straps in stores, go to any air conditioning company, and ask if you can buy a duct strap. They'll probably give you a couple for free if you ask nice.
Position the strap around the piston like this, carefully making sure both rings are under the strap, and the ring end gaps are still straddling the lock pins. Now cinch the strap tight enough around the piston to fully compress the rings.
Now you're ready to install the piston in the cylinder. Slid the cylinder down on the cylinder studs, far enough to insert the top of the piston into the bottom of the cylinder. With one hand hold the piston, while lightly tapping the cylinder down on the piston with your other hand. The cylinder should easily slide down onto the piston. After both rings are inside the cylinder, remove the duct strap by inserting a small screwdriver into the locking mechanism on the strap, and remove the strap from the piston. If you don't plan on reusing the strap, you can also just cut the strap with a wire cutter.
Now the cylinder can be pushed the rest of the way on the motor block. You know the rest.
