Go through the longest thread on mychinamoto--the one that probably brought you here; the one about the Dong Fang bobber. Those guys have sorted them out over the years, and continue to do so.

As far as any other bike, join us on www.chinariders.net because the majority of the members are North American based meaning that the bikes we mainly discuss are the one available in North America, while this site is very international and mainly discuss bikes not available to us, the exception being the very looooong Dong Fang thread of the bobber which is very much worth the read through.
