get married with Chinese, lol :D you wanna settle in Sichuan? good, girls there are hot :D

about owning bikes, I guess it's not a problem to have two or more bikes on your name in China. who cares?

but you should keep in mind few moments:
- motorcycle span life in China is limited to 13 years, after this period motorcycle should be scrapped. and you wouldn't be able to sell it, if motorcycle is 12 years old
- technical checking for new motorcycles should be performed every 2 years... only for first 4 years. 4 and more years old motorcycles should be checked on yearly basis
- if you'll miss checking, you'll be fined not only by money, also by points of your Chinese DL.

I highly recommend you to have your motorcycles on your name (or your close friend/relative). then you wouldn't have problems to get insurance, checking and other procedures done.

where did you left your bike in Chengdu? at Tako's place? then he would be able to sort out paperwork for you, just get it done in time. and ask ShuBen to help you with insurance and authority letter.
