Welcome and thanks for the link--you have a lot of information there! I am not sure if you are familiar with chinariders.net, but that site has many more North American members, so I am guessing you might find a fellow owner (have not recalled anyone mentioning buying one, however) or people interested in the bike. There are quite a few RX3 members, so you will have the engine to compare (I know, the US RX is 6 speed and fuel injected, but a few overseas RX3 members with carbed RX3s have joined us).
