Always always always use new rings on a new piston, you should also hone the cylinder walls at a minimum as well when doing a piston swap.

If the piston is new second hand as I suspect,I would as Spock says, use new rings,but if budget is lean, you could take the rings of the pistons, place them in the cylinder and check the end gaps. Use the piston to push the rings down the cylinder,about an inch,and make sure that the ring is level in the bore. Then use the ones with the narrowest gap. If a hone isn't available,use a bit of wet and dry sand paper and scuff it up in a circular motion.
Feeler gauges are the tool to measure the end gap, manual will tell you what the min and max gaps are. Cheers SpiritWalker.

Piston Top? That like a Muffin Top?

New piston? New rings, new wrist pin, new snap rings.

Trying to save money now will just cost you more later I've always found.

agreed KM.

this kind of repair is better done completely, with proper parts replaced will go a long way.

you do NOT want to pull it apart again after a few miles to replace a cheap part you should have done the 1st time.
