got my new piston and ring set it, got 2 small questions..
1. the "spacer" for the oil ring, can or should it be overlapped?
2. the top 2 rings only have "T" stamped on them, one of them has a closer gap than the other, which should go on top?

The "spacer" should not overlap. The end should be butted like a W. The T goes up, didnt the piston come with instructions? And what is it for?

Hm, most pistons come with atleast the gap specs. Anyway the top compression ring usually has a larger gap than the second one. Is one ring fatter than the other, that would be an easy way to figure out. And dont forget to gap the rings! That can lead to bad problems later on.

they are the same thickness, like I said, one has a significant gap than the other, so what u r saying is that the top ring should have the largest gap?

Yeah buy a manual. But right off my wiseco paper for my 200x it says .0040 for top and .0050 for bottom, so bottom would be larger Im assuming, and it just says for dirt,atv,snow and PWC. So I guess that would be what you want for yours. I guess I was wrong about top being bigger? I could have swore my 450 piston ring was larger on top.

compression rings are normally a different color like gold or silver
scraper rings are normally just black

I have looked at the honda manual, I wanted some hands on experience. The manual shows the end of the piston ring slanted for the the top one. Both of my rings have straight edges, only difference is gap size!

The top ring is usually shiny as Swigin posted....

my eye is not that great naked, I just need to know if the ring with the largest gap goes on top, or bottom (of the 2 compression rings)

The day begins with 3WW
ok i know what he's talking about. i worke don one of them lesser piston sets before.
both rins are the exact same thickness. the one with the bigger gap goes to the top.make sure the gaps do NOT match up. they shoudl be nearly 180 out.
make sure the 2 small rings are on either side of the oil ring expander. the side in a groove on either side and kinda on tope. if you look closely at it you will see the part that goes against the piston is slightly thicker than the top you see when it's installed. the 2 tiny rings will sit on either side of that top thinner peice but on top of the bottom section. thhat bottom section allows the oil to touch the sidewalls and the rings on either side are called whippers.
is there any marking on the rings at all? if there are any parkings. (stapmed or printed) they go facing up. if not, then there's no direction on the rings.

the gaps mean nothing...if he switchs them up it will never seal up.
