KMOT, Isn't RCV made in the UK? Or are they a UK company who outsourced their manufacturing to China? I thought that Sanye makes the Magnum, ASP and SC engines. Are there others too?
I just checked the Sanye website and it looks like the FS400AR is still listed. Of course, I don't think that they have updated their website in 3 years and the english site was never completed. Navigating the Chinese pages are pretty rough.
I'll list the website for reference, but I don't think that it will do anybody much good....

I once had my wife look at the website for me, but things like 2 vs. 4 cycle, bore, stroke, etc. don't mean much to her so I didn't get much feedback from her. (It's kind of like transating a law book).
