Getting the 50cc scooter up to snuff

I've been working on the 50 cc .... 2008 Jonway .... I have no idea what the history of this thing is... it shows less than 500 miles on the odometer. From the looks of the tires and condition it probably quit working a month after someone bought it and never ran again. I got it going a bit and it seemed good enough to see what I could do with it. I put a big bore kit on it yesterday and that helped a lot with the acceleration. I was going to give it test drive today but the front tire started going down, when I tried airing it up the valve stem fell off. So thus far maybe 8 blocks after installing the BBK. I'll run down to the "we got everything" store which carries a lot of tire repair supplies and see if they have a valve stem that will work. By the way the 100cc big bore kit for 50cc is only 50mm and if you do the math and it comes out to 80cc's not 100. I did check the ring gaps and they were right where it should be for a 50mm cylinder.
I guess I'd better go to the store and see what I can find for a valve stem.
