Back door seems to suit you. A couple of folk tried to explain to you that it wasn't advisable and you decided to ignore them and continue with your attitude that a 'stubborn headed' guy from Florida can expect other folk, perhaps honest folk or certainly cautious folk would explain to him, a stranger, on a public forum frequented in the main by foreigners living in China, but certainly also by a good few friendly Chinese nationals, how to circumvent the law?
That is foolish and deserves contempt and rebuke. It is an attitude that many that are not American find all too common, it is VERY frustrating and very arrogant. The Chinese have a right to set in place whatever laws they wish to. You of course have a right to dislike that, and to circumvent them too. But don't expect any member of this forum to publically support you in it, the world isn't set up just for an immature Floridean fool to ride his KLR wherever he choses.
And your remark about welds was ill considered too, your favoured maker of the KLR, had to withdraw two years worth of those bikes after 2008 because they were in some danger of catching fire due to a design fault and a retrograde step to cheap plastics. We are all well aware of the faults of China bikes, it is why we come here to this forum.
Perhaps if you introduced yourself more politely, with tales of yourself and pictures of your machine, you would be tolerated more by arseholes like me. I know I am an arsehole, you haven't learned yet that you are. Perhaps a few more folk telling you, will teach you that.
Unfortunate as you may have felt the Iraq remark to have been, and perhaps it was, it was meant to convey two things - you can probably do illegal things more easily there as your country has certainly destroyed the structure of law, and over there you will have tooled up mates to back you. Here, you are just a mouth.
Some advise. Of course you can get a bike illegally into China. It is not hard. A good few trucks cross the massive borders in several places every day! And ships. But would a truck driver, an underworld contact, any Chinese national willing to help, or someone on here who may actually knows how to do it actually respond to you?
Would they trust you to be loyal and not squeal if caught? Would I tell you how to do it? Never, you are just another arrogant, mouthy prick and therefore untrustworthy, you deserve to find out the hard way and pay top dollar in my eyes. Maybe one day if you grow up you will learn how to approach the rest of the world and maybe then you may make friends and contacts and gain power enough to actually function. Then you may achieve what you wish. I do not mind a good argument, so contact me privately if you choose to continue this. The rest of the forum may or may not be amused but I am willing to educate you further.
