Hello everybody, just got my bike running today. I bought the Bobber 250 and then found this thread... so, while I had spare time, I read almost every post in this thread. Barnone and Gumpsta, I feel like I know you. Thank you for the bountiful information. I purchased my bike from Killer Motorsports in Texas... funny thing is , Alex , who took the order told me that the bike was "in stock" which I took to mean it was there in Texas ready to ship... they drop shipped it from California. I was expecting a bike , a helmet and a tool kit, all I received was a bike. I e-mailed them about the helmet and toolkit and they asked me again what helmet I ordered....grrrr.... I was told that the assembly toolkit was probably in China... anyway needless to say the Customer Service Department at Killer Motorsports needs some improvement. The helmet arrived about a week after the bike arrived it's a nice half helmet, and I had to use my own tool kit to assemble the bike. No biggie.
The bike started and runs fine, finding neutral is a bit of a challenge while the engine is running I believe practice will help it. I adjusted the shift pedal a little lower to make shifting easier, that helped me with finding neutral a bit as well. The one problem that I cannot figure out is the little black hose running from the bottom of the carbuerator... when I turn on the fuel valve , gasoline flows freely from the bottom of the carbuerator. I pinched the line off for now to test ride the bike and it seems o.k. for now.... but... what is wrong with the carb and how do I go about fixing it. I tapped it lightly to see if maybe the float was stuck (I bet you guys just love that highly technical method of carbuerator repair... LOL).

I live in Chapel Hill , Tennessee and this is my first bike since I was 14 years old...being on the tail end of 41 makes it all seem poetically symetrical... =)

The carb problem is more than likely an improperly set float level.The fuel level in the bowl should be right at the mating surface of the bowl to carb body.I'm not sure if your carb has a bowl drain and drain screw.Here is a simple way to check it, if it does have a bowl drain. http://www.bbburma.net/FloatHeight.htm To adjust,simply bend the metal tab over the float needle in the carb.Bending the tab down lowers the fuel level and bending it up raises the level.

bobber250,
Welcome to the site and Dong Fang bobber ownership. There is a drain screw on the float bowl that could be loose, might want to check it. And it could be as you suspect, a stuck float.

You think it could be a stuck float?Anything possible with these bikes sitting around in warehouses for years.

Thank you all , I was just thinking about a loose drain screw...( was reading barnones post about the washers under the needle jet... "drain float bowl"...), jiggled the thought process a bit and would make a lot of sense. The bike arrived with the fuel line to the carbuerator disconnected, soooooo... if they tested the engine... meaning actually starting it up at the factory, they would have removed the fuel line to drain the excess fuel from the tank and also would have drained the float bowl as well. The bike runs extremely well when it is warmed up , I am optimistic that there will be a drain screw found when I go looking for one tomorrow.... I really would dislike opening up a fresh carb on a bike that just turned over 3 miles. I will try to load some pictures tomorrow. Are there any DF250 owners in Tennessee? I am curious about the possible hurdles the TNDOT may put up in my path.... I really love this bike.

I thought it was a possibility at first , but now... not so sure. I will probably find an open drain screw on the float bowl. I was a little worried about getting a 2008 model year bike... earlier research indicated that the manufacturers were shipping bikes that were produced 3 years earlier. My bike was built in November 2010, and for all intents and purposes would be classified as a 2011 machine. So the research information is outdated or an urban myth. Much of the erroneous china bike information on the web comes from Japanese bike retailers trying to maintain their market share. It looks like the biggest problem, IMHO , comes from the retail importer not fulfilling their promises to the consumer.

I couldn't wait... I went out in the dark with a flashlight and a screwdriver and found the pesky little drain screw and closed it... Its beautiful.... a work of art... Thank you sir, sometimes my elder brain needs a kickstart...
