Re: Dong Fang DF 250 RTB Bobber Information
shut the gas off , drain the carb pull the main jet make sure its bigger than 100 , stock was something like 86 and is to lean
popping under acceleration is usually lean , on decel it would be emissions systems
the pollution control air injection makes it "pop" wont hurt it just annoying , and can be deleated
im in austin tx , if nearby can show ya if we can set a meet

Re: Dong Fang DF 250 RTB Bobber Information
Thx DanDaMan, Its not as bad after riding it for 15mins. Seems to do it on accel mostly. It may be me since I tend to shift to late. If I shift gears earlier its not as bad. Just started riding it as I just got my M Lic so its all new to me.
One thing that I find annoying is the vibration in the handlebars. I trained on a Yamaha TR 250 and it had nowhere near the vibration going to my hands. Then again I may just be a wimp and didnt know what I was getting myself into LOL. But the vibration seems to numb my right hand to the point where I cant feel my fingers. Maybe I should see a doctor instead of a motorcycle forum?
Doest matter though. Bike is mine and its a keeper. Love the freedom of riding and love the looks of the bike. Eventually I will work out all the bugs. I find myself constantly rereading this thread when I have time. Man its big.
Cant make it to Austin, gettin married soon and going to west TX for honeymoon. Thanks for the online help though. Im a total noob but I do remember taking apart a 4bbl carb in auto shop in HS so this shouldt be too hard to figure out. IIRC there are photos in this thread of it somewhere.

Re: Dong Fang DF 250 RTB Bobber Information

Re: Dong Fang DF 250 RTB Bobber Information
Cool, where can I get the jet? Ebay? Have no clue where or what to look for online.

Re: Dong Fang DF 250 RTB Bobber Information
Got my new sprocket in on sat.had to go to the hardare store and get me some grade 8 3/8 -16 bolts,about 2 1/4 inches long,cut them to the same length as the previous studs were,drilled out the hub grommetts..with a 3/8 bit,as well as the holes on the new sprocket.I am having the weld shop weld on some backing washers to the new studs I made,so they attatch to the sprocket correctly.
I noticed that the right side chain tensioner(if that is what it is called) was bent.I guess i hit a pot hole(all over teh place around here) pretty hard enough to bend it,and I think that is why my sprocket studs snapped..looks like the wheel got a bit off center to the bike cause of it.Got the weld shop fixin that also.
Next step is to get the chain on minus a couple links.Anyone know where to get a relativly cheap tool to do this?Or somewhere to rent on perhaps? after that I put her all together,change the oil,fine tune some stuff..and hopefully back riding by sunday.

I adjusted my chain yesterday. I undid the axle bolts and noticed that the right nut was angled a bit almost like it was crossthreaded when they put it on. But it worked just fine. Did not take it all the way off to check the threads but maybe I should have. Tightened fine and I put some blue lockttight on it. Seems they put the red locktight so maybe I should get some of the red instead.

Re: Dong Fang DF 250 RTB Bobber Information
Good day all, I have just joined so please excuse and errors I may make in forum protocol. my name is Kevin and I currently reside in Stuart Florida. I found a picture of the DF Bobber on line and loved the look. I found this thread while researching the bike and have been reading it the last couple of days. Though it is very informative I am still a little confused on the best way to buy one. Seem's like there are a lot of mixed results with different dealers and shippers and waiting for the paperwork. Is there a consensus among members on who to use when ordering? I do not like the idea of waiting weeks for the paperwork to register the bike. I've also never been good at handling buearacrats. I can register the bike in either Texas or Florida. I also travel around the gulf coast a lot so I have some flexibility in that regard. Any information would be greatly appreciated.

Well Im in TX and got it from a TX dealer. Killermotorsports.com. Not all that impressed with the customer service but on the bright side they are doing the plates and registration for me. Took a month to get the bike and seems like it will take another month to get the plates. But they did email dealer tags so I am at least riding the bike legally on the street.

Re: Dong Fang DF 250 RTB Bobber Information
Thanks for the info. I'm in Beaumont/Port Arthur for the next couple of days before flying back to Florida. I not sure how to go with this. Would prefer to order on line and have delivery at my place in Florida. From what I have read here it seems both Texas and Florida doesn't have a problem with registration. Guess I will keep researching until Someone turns up who had a good experence getting their ride and paperwork. hope that doesn't take to long. Lol

Re: Dong Fang DF 250 RTB Bobber Information
I live in Houston Tx and I delt with Scooterdepot.net. I have dely with them once before with a 150 scooter i purchased about 5 years ago..and I was very satisfied with everything,so I bought the Bobber from them.The bike arrived within 3 weeks of order, and i got the paper work with the bike when it was delivered.I tagged it the next day.I have also dealt with the parts dept on a few occasions,as this bike is what you pay for,and upgrades are the best idea.I needed a few items to be replaced,and since I purchased the extended warranty I got most everything I needed without a headache.of course basic warranty has expired and I still have until august on the motor wraanty..but overall,(I am a very easy going guy and have parience)I have been very satified with everything to do with scooter depot.
If you have been reading the whole thread you know of the ins and outs of the upgrades, and most of the mishaps the bike comes with.from my point of view,the bike is well worth the sticker price.I guess you get what you pay for is realy true with this bike.I am pleased with it's performance,although I am in the process of upgrades,but overall it is a good starter bike to tool around on,and with the tweeks and additions,I iwll be freeway bound soon.
Good luck in your endeavor,I would recomend this bike to anyone.In fact I have.

Re: Dong Fang DF 250 RTB Bobber Information
Thanks Bowtiewagon, I read over a hundred pages, but not all, not yet. Makes for some fascinating reading. My biggest obstacle will be persuading my wife into buying a bike that doesn't have a back seat for her.

Re: Dong Fang DF 250 RTB Bobber Information
I was wondering if anybody could tell me the size of the handlebar. Its not in the manual.
I need to get replacement handlebar grips. The ones on it are terrible.

The solo seat is the bikes best feature. :naughty:

OK thanks. Started looking online for some and realized that some bikes use two different sizes. I never thought of that since this is my first bike.
Anyone know of they are same size left and right? My main concern is the throttle one since the vibration is killing my hand and making my fingers numb to the point where its dangerous.

what do you mean left and right? left and right side of the handlebars? the handlebars are the same size all the way across, 7/8". if you buy new hand grips, one will have a smaller hole for the left side and larger hole for the right side to go over the throttle tube. your hands might be going numb because you're holding the bars too tight, mine used to go numb when i first started riding but after you get used to riding a lot you loosen your grip, lol.

OK that makes sense. Im a noob and did not know this. I will also try to loosen my grip but my throttle seems a bit tight. I guess I need to figure out how to get some oil down inside the throttle cable. Dont see an easy way of doing that on my DF. Guess I have to take the throttle apart. Will try that once I get some better grips.

Re: Dong Fang DF 250 RTB Bobber Information
OK I messed with my bike lights tonight. Noticed that running lights work fine with ignition ON. Turn high beams on and nothing. Press the button for passing light and high beams come on.
Does the bike need to be running for the high beams to work? I did not want to start my bike at 1am so figured I would ask here. I do remember somewhere in the thread that somebody had a similar problem.
Small bulb lights for running light. High beams do not work with switch but do work with passing button and center bulb comes on. Are there two elements in the center bulb? Or is my wiring messed up somehow?

Same as mine, bike needs to be running before the high beams will come on. Passing button works but the brights will not turn on until I start the bike. Go figure.

Re: Dong Fang DF 250 RTB Bobber Information
Just organised at DF250RTB in the last few days, I am based in New Zealand and have arrange with a logistics company I use to sea from California. Bike arrived at my shipper this morning , not wrapped at all and definitely no crate so thet can't send it. I won't mention the site I got it from yet until I give them the chance to rectify. If they don't I will have to pay US$400 crating fee!!
Regards Matt

Matt, hang in there. Cannot imagine that there is no crate. Is it new? It will be worth the wait once you get everything straightened out. Take off the air injector and change out the rear sprocket and you will be happy with it. Be patient breaking it in though. And don't forget to change the oil out before anything else. When checking the oil level the dip stick is just placed in the opening, not screwed back in with the bike sitting straight up. Get the magnetic oil drain plug too.

Re: Dong Fang DF 250 RTB Bobber Information
Just wondering,I see alot of you discussing the air injector?What is that and where is it..also does it boost the horse power any?
On another note,I guess I will have mine back together this weekend.Been so busy with work and the kids school functions I haven't had a second to myself.And wouldn't ya know it the weather has been real keen for riding,and i haven't been able to. They say the weather is gonna be about the same all next week.. but a weee bit hotter.. right now just hitting the high 80's low 90's..so I think a weeee means we will hit 100 by tuesday.Glad I have a silver helmet... the last one I had was black,and I could feel my brain melting at every stop light. But with this new sprocket..i may be on the freeway a bit more often than normal now,so I guess it was a blessing in diguise that the studs snapped.

Re: Dong Fang DF 250 RTB Bobber Information
Thanks ghost , yeah can't wait for it to arrive. I will have to try and find somewhere to buy the socket that will send down here.
Re the bike packing after further investigation the bike is wrapped in the metal cage on a pallet etc but its not sufficient for export so I have to arrange crating in heat treated wood with fire proof pallet. It has been a real learning curve! Then once it arrives I will have to try and get it complied here which will be another experience

Re: Dong Fang DF 250 RTB Bobber Information
mine arrived in a metal cage wrapped in cardboard , on a cheap normal palet
and yes bike needs to be running for headlamps to light
air injector is the tubing running into the motor near the exaust pipe , it doesnt add horsepower , its an emission control (burns excess fuel in the catalitic converter) , on decell it makes it pop a bit , and hurts nuthing to remove it , unless you live in a state that uses a sniffer on motorcycle to pass inspection
