BTW, visiting his shop yesterday, he showed me a sizeable stack of carburetors that had all the adjustment screws & access ports factory sealed. All junked after failed attempts to unseal them. They were all pumper types, and I'm guessing all off of scooters, like the factory is making a concerted effort to prohibit altering or adjustment. Is this perhaps a mandated EPA requirement? The bobber has a reed valve carb doesn't it?

No. it has a PZ30 pumper carb which can be easily modified it needed. The new DF's seem to be coming with 105 main jets so no modification needed. Mine came with a 88 so was very lean.

I'm wondering if anyone knows of a dealer near here...Myrtle Beach SC.... or better yet, is there anyone who may be making a trip to Myrtle Beach on one anytime soon? It's definitely worth a beer & a great seafood dinner if anyone would like to meet up and let me see one "in the flesh." It's worth it for me to find a nearby dealer, for anything else than to have a stick & mortar place that knows the bike & can offer parts & service if needed, that, along with having someone familular with bikes to properly set it up the first time. I'm no slouch turning a wrench, but without a good garage or shop, I'm a bit reluctant to try to assemble a motorcycle for the first time in my dirt driveway. How'bout it? Anyone planning a trip to Myrtle Beach care to show off their scoot?
On another note, there is a "Chinabike" Dealer here... but I can't seem to get him interested in ordering the bike, (naturally he'd rather I buy something he already has in stock). Any suggestions as to how to persuade him that ordering a DF250 Bobber or five would be a good idea? Thanks!

Welcome ConwayBob, its not difficult to assemble the DF. The UPS driver delivered my bike and could only back halfway down my drive way so he had to drop my bike about 500 yards from the house and shop... I got a handful of metric wrenches and sockets and a couple of Allen wrenches and assembled it in about an hour and a half. I found it to be easier to assemble the bike before I removed the "stay" wires. I would recommend getting someone to hold the bike upright when you remove the wires though...you could manage it by yourself but you really dont want to drop your new toy before you ever start it... LOL...Anyway, the DF is a fine machine, it feels good and sits well for me 6'2" and 240lbs... barnone has modified his carbuerator a little with success, but it has been discovered that some of the carbs don't need different jets. IF you decide to go ahead and get one .... be sure to read about the difficulties some of us have had with the dealers. I think that the DF is the better product above the others just for the price.... the kikker comes as a 150cc that you can "upgrade" to a bigger engine but then the price shoots up higher than the DF, besides Kelly Kikker has an attitude problem from what I understand and he may decide to not sell you parts.... the bike offered by CCW is a good bike and runs about $1000 more than the DF , but you DO have dealers across the country, we have one here in Nashville TN. For the extra grand you get the added convenience of a brick and mortar location that offers product support.... get the DF... its really cool, you will love it when you see it.

Need help. going thru break in & getting an intermitent spuder constant speed & backfires some times during de-acceleration.
Front suspencion hard, I thought the back was to be, it's fine. Any bump literally hurts hands.
Headlamp adjustment limited. Too low at max up.
Neutral after dropping into 1st won't happen. If you gently tap down from second it happens.
Handle bars 5" to far forward. Is there a way to bend bars back?
Hand book break in says 75% gas , sticker on motor next to dip says @35mph max for the first @100 miles. Doing that now & will follow 75% for the recommended future miles. Doing one hour rides with 2 hour cools, they recommend 5 cycles.
Is there supposed to be an element inside the air cleaner's metal cover?

Other wise as much fun you can have with your cloths on. Love my new toySD530490.JPG SD530491.JPG

Man alive, the bike just plain looks better in black matte.... almost no chrome... and no cheesy stripes on the tank or fenders. You get first prize for "Best out of the Box" Category in my opinion.

Nice pictures.

**bobber250** · 10-09-2011, 12:31 AM

So, I was sitting at work yesterday and had mentioned that I had a new bike, my buddy asked to see a picture of it and when he saw it... he said " is that a Harley?"... I told him with all seriousness of expression (straight faced...LOL), "NO... that bike is not a Harley... it's a 1932 Norton...." ( I love that one and have been using it for the last couple of days...LOL). My buddy says " NO SH*T?!!".... to which I replied "no you dumba$$ its a DongFang Bobber..."

Now he wants one.... I can't believe that cycle shops aren't selling these bikes more, they just sit there and people get the uncontrollable urge to buy them....

You got the black on black model for sure. Looks good with the black valve cover.

You might need to check your main jet size. Mine came with a 88 main and it would not run out and had that annoying back fire on deceleration. I put a 100 main and a washer under the needle and that fixed that problem on mine.

Front end is stiff and should loosen up a bit with miles on the bike. Looks like you need to lower your handlebars in the riser clamps. Rotate them back a bit. Don't put a death grip on the handlebars.

My headlight adjustment is fine. Can you take a close up photo of the headlight area and maybe we can spot something wrong there?

Hopefully the gear box will loosen up a bit. Make sure your chain is not too tight.

The air cleaner is the wire mesh. You need to put air filter oil on it.

is it common for motorcycle batteries to die if you don't ride for a couple weeks? i haven't ridden in a couple weeks cause i came into a turn a bit too fast, hit some gravel and dropped the bike. i'm fine and so is the bike for the most part, i just cracked the clutch perch, and bent the the footpeg just enough to bind up my shifter. anyway i've been waiting about a week and a half now for scooter depot to send my new parts and wanted just to start the bike and let it run a bit today, and my battery was dead. is this common or do you think it's something electrical?

**barnone** · 10-09-2011, 01:00 PM

Probably a bad battery. Mine went bad and I replaced it with one of the same brand (only one that fits the box) and it's gone bad (10.7 volts). Crappy batteries.
I've ordered one from http://www.batterystuff.com/powerspo...09A2-BS12.html that is suppose to be the cat's meow. Will let you know in a few days.

Removing my battery to charge (unable to attach charger clips in place due to the metal case shorting the pos clip) I ran into a clearance problem with the rear brake system, had to unbolt to get the battery out.

Barnone what information have you found with the tach. What are the readings at run up & cruise?
Thanks for your feedback regarding my whine list.
