sounz like they over bored it, and the crank case could be wet sumped with gas, tell him to take it back to them.

Yeah - if he had "someone" do it, shouldn't they stand behind it??? Sounds like they didn't know what they were doing.

Pistons don't "just break", you usually have to try to screw them up for a while to get them to do that...

First thing I would do is hook up a compression guage. I would say it should be at least 120 lbs and more, depending on the machine.With a fresh top-end, it should have some good resistance on the kicker.
You said you can roll it with your finger. That ain't good. I am willing to bet that it needs a bore and an oversize piston. Maybe it just needs a honing so the rings seat to the cylinder.
Bring the jug/piston to a GOOD motorcycle/ATV shop and have them take a look.
If they tell you that it needs a bore, I would be making a call or two to the other guy who looked at it.
As long as you got all new gaskets, and installed and torqued them properly, you should not have a problem with compression with a new piston/rings.. Sounds like whoever inspected the cylinder and put a new piston in just did a quicky, no give a care job on ya.
