All this info from everyone has been great. I just have yet to decide what i am gonna do. The inserts in the hub are a tad smaller than the threaded end of the stud.So the bolt holes on the sprocket are slightly bigger,and if i find something to fit into the the inserts in the hub..then the size is too small for the sprocket and will cause issues later. If I remove the inserts,then I have a big hole to deal with.Putting a heli-coil in the inserts only brings me to a smaller bolt for the sprocket... Plus I am thinking too hard on this..and my mind is numb.
Dan- a link to where you got your sprocket would be great..I figure since I already have this apart ..I should get the sprocket now.I like the way yours sounds like it turned out.
Maybe then i can figure out about the studs and go with that. I may just go ahead and order the studs from scooter depot today.. and hopefully get them within a decent enough time.But at the same time order a 36 tooth sprocket while I am at it.

Barnone's link for sprockets http://www.oldbikebarn.com/Motorcycl...?search=JTR279 ---- model number jtr279.35

I have a 428 DiD chain I got the sprocket for it from http://www.rebelgears.com/pricelist.html , while yours came with a 520 stock chain so you need the 520 sprocket

old bike barns cheaper , but didnt have the 35/36 tooth 428 : \


oh ya , get yerself a few strippers http://www.boltdepot.com/Shoulder_bolts.aspx?nv=l the larger shoulders than threads fill the sprocket holes , you would prob have to carry the sprocket and insert u intend to use into store for sizing

Dan you ARE the Man.. thank you thank you thank you!!!!!!!!!!:thumbsup:

Trying out my new camera on the DF250TRB

http://s1229.photobucket.com/albums/...t=Untitled.mp4

I want to gear up my d250rtc. So the Honda Rebel, etc sprockets fit these?

http://www.oldbikebarn.com/JT-Rear-S...9-35T-35-Tooth

Thanks

yup the bike is really a honda clone , right down to bolt patterns , with just minor frame adjustments to make about 5 diff style bikes

I would even bet the little rebel 250cc twin motor would bolt right in , or even the fuel injected CBR250R motor

Found the df250rtb on this site for $1895.00

I own one but thought it was a good deal if anyone was interested. No, no affiliation.

http://expressatvs.com/proddetail.as...linenumber=622

Site is slow to load?


Here's mine.

Attachment 7087

Hi all! New here, Have read every page and am this close to ordering a DF. The expressatvs after adding shipping and 3 more months warranty ends up pretty much the same as everyone else- or higher. Found one here:

http://www.mygokarts.com/250cc-manua...e-mc-df250rtb/

for $1919 free shipping but I haven't been able to verify the site.

Anyway, love all the posts! But I am a little peeved all of barnone's pics are gone! Why delete all the pictures grrr! I just haven't decided whether to go with the DF or buy a used Honda Rebel for $900 locally. Decisions, decisions.

Best, Xeta

I bought a DF250rtc from ScooterGasMotor.com and I have no complaints. It was $1759 + shipping, extra warranty, shipping ins = $2236 Total.

The one they have listed is a JinLun JL250p, but they ended up shipping me a DongFang 250rtc instead after confirming the shipping change with me, which ended up being a good thing since for whatever reason the JinLun is not able to be licensed in FL.

Contact: "Jason @ SGM" <scootergasmotor1@gmail.com> if you are interested.

Word of advice: When doing final assembly out of crate, go through bike thoroughly and make sure ALL bolts are tight and use blue loctite at your discretion, and check fuel lines, brake lines, and vacuum hoses for kinks. The QC on Chinese bikes isn't the greatest.

Beware of some of the sites listing very cheap and make sure they aren't trying to scam you, asking for money order payment.

I just realized after writing all this that you were looking for the bobber model not the sport model :\

ok im disappointed,i made a call to my dmv in new york this bike will not be allowed to be registered,law pass in jan 2011 needs to be CARB approved,you think they would be more worryed about the buses pouring out black toxic fumes
over alittle 250cc mc,next we will be told how and when we could wipe our asses.we need to bring back the 70's 80's when nobody cared and worryed over ever little thing,next thing you know they will be making everyone pad there walls with four inches of cotton so when we stub our toes we wont get hurt.






that law is for all five boroughs, must be carb approved.

Manhattan, Brooklyn, Queens, The Bronx and Staten Island.

Let your brother that lives in Allentown, Pa. register it in his name. If anybody asks he let you borrow it for the summer.

Same law in CT. As of 2008. I FEEL YOUR PAIN !

Can these bikes not be brought up to code? How does anyone build a bike from scratch and register it then? If you have the bike registered and they change the law- what then? :0

it's band for pa also.if you had the bike before carb went into effect they give you a you pass.

Thanks everyone for all the info on the dong fang. Like a lot of people im still up in the air on it. Those of you that have had their Dong Fang bobbers for a while do you still happy with your bikes, or all the little china built problems making you regret it?

Thank you much..

lol peaple always ask that , "how do you handle all the little china problems"

I say "what problems" , besides light bulbs and gearing its a dream machine , all fixed for under a hundred bucks

I agree with Dan except I haven't had a problem with the lights other than the head light could be a little brighter.

Well as you all know I was totally screwed on my DF, after a lot of money sunk into it it runs like a champ and I will go game my mc test tmrw. I rode it around today and it sure is snappy.http://i1214.photobucket.com/albums/...IMAG1413-1.jpg http://i1214.photobucket.com/albums/...36IMAG1412.jpg

http://i1214.photobucket.com/albums/...36IMAG1412.jpg

Great thanks for the info. I will use this bike to commute to work a few days a week. Anything in owners manual about riding in the rain? Like not to do it?

Good looking DF250RTB, looks like it fits you, or you fit it. Lol. Why did you have to sink a lot of money into it? What did you have to do. Although the mods listed here are a must. Like the magnetic drain plug, Sprocket change etc. Good luck with the MC test.

P.S Get some boots. Tennis shoes on a bobber means limping around in your old age. I know. I am that old age limper.

If you ride the DF250RTB in the rain, something terrible will happen. You will get wet.
No power washing allowed. Hand only.

Neutral. A lot of posts on here about hitting neutral. On these bikes sitting still at a red light, good luck. Not these bikes specifically, all older bikes. Trouble hitting neutral at stand still while the motor running is not a flaw.
Common practice from way back, I come from way back. When rolling into a red light, or stop sign is to gear down and hit neutral before you come to a stop. Sitting for any amount of time with the clutch cable pulled is a no no. You'll end up with a broken clutch cable and wear out your throwout bearing real quick. So try and get into the practice of when approching a red light, gear down and hit neutral about twenty feet before you stop and roll into the stop. Besides saving your clutch, you appreciate being able to sit at the red light and have free use of both hands. Adjusting your hat, jacket, whatever.
Light up a smoke. Flip off the guy who pulled in front of you with both hands.
Really though, try and get used to hitting neutral before you come to a complete stop.

Haha ya I have riding boots, was just taking it for a test ride when I got it back from the shop. Jeeez I look old? Lol I'm only 25 but yes I'm bald lol damn military will do that to a guy. Well when I got my bike it had a broken blinked lens, no foot shifter or linkage, no mirrors, none of the lights worked, the back axle was crooked and the tuning was so messed up it wouldn't even run for 2 minutes. I probably forgot some stuff but ya a bike builder I work with helped me with it now just new to plate it and get my license.

Took my MC training class and passed. Will get my Lic R designation tomorrow I think, if time permits.

Got a question for you guys: Has anyone ever moved the seat forward on one of these? I see a hole on the frame just forward of the seat front mounting bolt. It looks like I may be there for that purpose but Im a bit gunshy about unding the front seat as it looks like the shock spring is already stretched.

Any suggestions or experiences with this?

that hole is not for moving the seat forward, it should have a little bracket screwed into one side of it that holds your wires. i've changed my seat completely and trust me once you remove the bolt from the front seat bracket you'll quickly realize that it would not fit in that hole.

Yeah I realized that last night. You are right. Guess I need to just get used to the reach or consider different handlebars.

On the bright side, I got my motorcycle license today. Simple 20 question test.

But now that I am riding the bike I have a new issue. This thing sputters and spurts a lot. Not sure what could be causing it. Exhaust kind of pops. Im thinking that the bike may be running a little too lean. It doesnt do this at idle. Idles just fine. Any suggestions?
