Hey I am just replacing my piston rings I am burning a lot of oil! Haha but I called Honda as they said like 64$ for OEM rings for one pisten so I would have to buy 4 sets. This seems a little steep! Anyone know who sells good ones? That aren't that much?

You could try one of those genuine Honda part websites that sell them at discounted prices but you might make up for it with the shipping.
If you're talking about after market piston rings, you have OEM Stock pistons, so you will need the OEM stock piston rings, they're good for a lot of power anyways, plus OEM usually seems the most reliable anyways.

I found this website! Which rings do I need for a stock set up?

I'm pretty sure you determine that after looking at your piston rings, if you want, replace them all lol.

Have you checked/measured the cylinder bores?

Well I cylinders aren't bored. So would someone know the stock size for an ap1?

He means check the cylinder with a bore gauge because over time it can change due to use. If the measurements are way off, you may need to bore. If they are within some allowable range (like .002" i think) then you just hone them and are good to go. As for stock size... shouldn't matter as long as you are buying the stock pistons. Just check to see if you have type A or B.

Either way you look at it, you have to size the rings for each individual cylinder by fitting them, measuring end gap, and using a piston ring filer to open up gaps if needed.

Not really sure you know what you're getting yourself into. This probably isn't one of those jobs you should be tackling yourself. Take it to a trusted mechanic, have him remove the head and measure and determine what you will need. It will be the safest and probably end up being the most cost efficient way. Sorry but you sound very confused and unsure of what your talking about.

A new set of rings will never seat properly unless you hone the cylinders. It also takes a special honing tool to do FRM lined cylinders. If you are going to go to all that trouble, you might as well get the OEM oversized pistons.
