Hello to all. I have in my possesion 2 x1 mid bikes. One of them I stretched 8 inches and plan to make it the better of the two. Mainly because they were both used and i'm using both bikes the make one awesome bike. But i am having some problems finding a good web site for oem parts and performance parts. Can you guys tell me where you buy yours at? I'm in need of some new trees to replace the cracked one's and a new front fairing. Also i was wondering since it has the 43cc engine do i need to buy a 49cc engine and put on a big bore kit to get it to 70cc, or can i use the same big bore kit on the 43cc? Thanks in advance..
