If I was to make a slightly educated guess, as I wrote about the whole lineup being found on one certificate, the seemingly same engines are NOT the same engines, LOL. You wrote above your theory, so combine the two, and my guess is they are fudging the EPA!
I just want to say that I appreciate all the years of information this thread has given me. Whether it be deemed by some as incorrect or perhaps even the backyard mechanic way it has helped in one form or another. For the record as well. I have a friend who goes to the salt flats with a buddy of his who runs his suzuki there. He checks his spokes every run... by tapping them with a wrench to hear the right pitch.
Anyway. The information always finds a way to help out. Making it easier for me to actual search out what I need. So all information is always taken with a grain of salt. For the simple reason ,from my view, I am the one doing the work. If I feel it to be a bit iffy, then I double and triple check. When it feels right, I do it.
Now onto other things. i still require the size of the front axle( bolt) would it be 12mm or 15mm? I am looking other speedo gears and they have different sizes. Thanks.
bow,
I went out and took the nut off the front axle and on the threads it measures a little bit less the 15mm so I would say it is a 15mm shaft. Definitely not a 12mm shaft.
No guarantee!:lol8:
You the man Bar. Thanks. I was figuring it to be that, as most of the research I have done pegs the 12mm for scooters.
Sold my DF today to a happy new owner in Naples Fl. He took it for a test ride and was satisfied with the bike.
Thats awesome. great way to end/start the year. he should enjoy it as much as we have. Did you hook him up with this web site? he may need a hand now and again.
I sent him the website address.
Wow--end of an era of sorts! You started this thread; this thread is the longest and most read thread here on mychinamoto!! Not that the thread will go away, but it will be different with you not being here, or at least having a bobber.Quote:

Even a big bores is made to fit only one bottom, that im aware.
before i trash my perfectly working bottom end, any one need any parts off it?
again its the stock DF 167fmm, let me know your terms and well see if it makes sense for us.
thats everything from the bottom end including starter, and exhaust pipe, carb, ect...
also I have one of the original aluminum push rods,
a set of OEM quality steel push rods,
and a set of aftermarket steel push rods.
you will not likely find push rods ANYWHERE, afaik...
Anyone know where to get replacement rear sprockets! Spring is coming fast and I need to change the stock sprocket! Will the Cleveland cycledorks 39 tooth fit? Doesn't say if it's for a 520 chain! And where can I get a bigger pilot jet?
Anyone know of weak spots in the electrical system? I know Previously Barnone mentioned there were no fuses on the bike. Checked the voltage on my battery and shes good, but absolutely no power to the bike whatsoever.
there actualy is an inline fuse on the red{power}wire from your battery hidding in the fake oil tank. Check that.
How far can you travel on this bike with out problems for the Dong Fang DF 250 RTB Bobber im buying my first bike in 4 daysQuote:

How many miles can u get on a tankQuote:

I get between 65 and 70 a gallon. I usually stop and fill up every 60-65 ( paranoia maybe?) But it always cost me less than or even with station cost per gallon. My tank is custom, holds a little over two gallons.
Did you get your bike? If so, where did you get it? Post a pic.Quote:

Hi, Im new here. I've been searching for a df250rtb and cant find one anywhere. does anyone have any information were I can get one?? thanks !!!
Your best bet is to try the source to see where they can point you to. If they are out of stock, and have been for a while, they can also let you know that as well. Plus, are more coming or are they sold out for good. http://www.df-motor.com/contact.asp
The Dong Fang DF250RTB has been discontinued by the manufacture! That is the information i have gathered from multiple sources! My buddy just bought a Dong Fang Ghost RTR but so far it is just plagued with problems! My Dong Fang RTB just passed 2k miles and running strong. Free flow exhaust, 110m-42p jetting, .002in-.003ex valves, 38t rear sprocket! 70mph is about it before your pushing the motor to hard! Attachment 20104Attachment 20105
I am back for just a look see at what is going on. I still have the 2015 Ural CT and my only other bike now is a 2009 TU250X.Bought it used several months ago with 1200 miles on it and it is like a new bike. Nice size to ride around here in the mountains. So there is no more new DF250RTBs available? Every place I looked was sold out. I wonder if it was a problem meeting EPA. Still waiting for the Genuine 400cc to be available in the USA. Miss my DF250RTB some.Quote:

Buyer beware! Most of these places are drop shippers and have no idea what stock is available. Plus, they rarely update their websites except to add something new.Quote:
