well, i finally took my engine apart... here are the pictures i took. as you can see, a little peice of aluminum fell in to the engine( from the aluminum intake) and caused the rings to melt into the piston and covered them with aluminum, the scooter ran for 4 or 5 days without too much issue while it was like this( that is untill the rings got stuck). may have overheated a few times but as long as those rings were free enough to create the compression it ran like there was no issue. (images are large so they may take a while)    picture of where the peice of aluminum came from  the jug looks like it is verry damaged and rough but in actuality it is very smooth and if i used a very light hone stone ( only a few passes) it would be fine |

it was from the intake ( the part that connects the head and the carb.. )

Looks almost like when you rev your engine too hard (or without oil) at engine break-in

Kinda does look like it was low/no oil.. maybe the oil pump went south?
I'd check the pump just to see, even if it doesn't matter.

It looks like some aluminum got in there and welded the rings to the piston. Wonder where the aluminum came from. Sorry apparently the thing to do now is post with our reading first. I thought I would do it too so the cool kids would like me.
Really that sucks. Sorry to hear it

Congrats on the work you've done. sometimes the best way to find out what is broken is by taking it all apart and looking at it.

See the first post prodigit, it was from the intake. The piece of aluminum missing in the bottom picture is what caused it,there is no other damaged areas of aluminum.
