    Got this last week, and with the ULTRA rare snow day in South Louisiana, I HAD to get her out and take some pics. Enjoy!

    Funky cool new retro bikes. I've just done a couple hundred km's getting mine thru the annual Chinese inspection process.

    Also tooled around the countryside of Nanhui district for a few hours with my buddy Dave.

    nick, you are in Shanghai? my Chang came from there! I got it from the guy who had it imported and also rec'd all the shipping and importation papers. He already had it titled, so it was a cakewalk for me to get a plate on it.

    Nice bikes you've got there. How's the OHV run? Much quicker than the 24hp I bet!

    I am.........the OHV has a bit more get up and go than a flattie but you only really notice it on a freeway type environment. Then the lack of a brake comes into play.

    Getting the correct paperwork for US importation is easy if you know what to get. It's actually harder to get authentic paperwork for an original old bike than it is to get "new" vintage paperwork for a new bike as older Changs are officially taken off to the scrap heap after 11 years of service. In the past the scrap value was more than their legally un-ridable value.

    Real vintage machines 25 years + are getting harder to find and are increasing in value even here.......60's and 70's era machines in good condition are more valuable than the new ones even though you cannot legally ride around on an old one, up to double and sometimes over the price for a good condition original vs new. Early to mid 80's are starting to appreciate.
    That's why the claims of "real" vintage restored exported bikes for sale at low prices are a bit misleading..........generally they are 11 year old bikes that have sometimes only undergone cosmetic restoration or had a the cosmetics and a new motor slapped in or are just new bike made to look old with "vintage" paperwork. No big deal because a 1 year old bike is pretty original to it's 23 year old cousin (about the time the 12v motor was introduced)........there a a few subtle frame variations that occur on older bikes but even those tell tale signs are easy to fake. It's easy to build a new 6 volt motor out of old NOS parts and they still put 6 volt motors into factory made bikes into the 90's so the old style motor is no indication of age. The bikes are still in production today, officially and semi officially. And I've seen a batch of old "new" 6 volt motors. So buyers shouldn't get to hung up on claims of vintage...........just enjoy it for what it is, a bit of time capsule bike from an era when simplicity was in.

    Anyway a fun bike and for me enjoyable to look and learn about the history of this quai-classic that can trace it's roots to prewar Germany via the Soviet Union.

    Even more obscure is the Donghai..... only came from one factory and that factory and it seems the tooling has long gone.

    P.S.

    Your bike will run better with 1.0 - (1.10 main jets if the exhaust has had any modification). Stock they are usually 0.93 although some don't match from carb to carb.
    It'll use a bit more gas but will run cooler and have a bit more power. Putting an exhaust crossover pipe in the system also helps gives it a bit more oomph and a smoother idle, opening up the mufflers even more.......I have some old stock Harley XL sportster mufflers on mine, probably 10-20 years old, they sound nice, louder than stock Chang fishtals but not too loud and the sound is much better than the straight pipes may people put on.

    I have disdcovered that under load, I can get a little bit more "juice" by putting the choke lever halfway. I have heard that thsi can be bad on the valves, but it does agree with your statement about the bigger jets and running the bike a little richer.

    That's my question. Where can I get bigger jets, or, what size drill bit would make them a 1.0 or 1.10. Is that 1.0 and 1.1 mm? I have micro bits of various sizes (#72, #74, etc.) and thumb driver.

    Thanks...

    Yes measured in mm...........I think Keihin carbs use the same style jet.

    I had some made up locally from a contact I had at a carb factory.

    There is also a useful semi-technical board on yahoo. http://autos.groups.yahoo.com/group/thechangjiangexperience/messages
    You can pick up some good info there but don't critique the brakes or the moderator. :D
