I would do both and get an average. Then add just a ouch more. Some fluid gets trapped in the bottom of the fork slider under the dampener rod.

find some fine wire and stick it through the jets. and look else where for a problem like exhaust seal or intake manifold leak.. not too many issues can't be solved rather than replaced.
that said this new rebuild kit has everything.
http://www.ebay.com/itm/272689779764
the jets are pretty close if ur not picky.
without a slide, cheaper
http://www.ebay.com/itm/291807976434, but no description of jets.
or if u insist the whole thing cheaper than you posted.
http://www.ebay.com/itm/322477941584
if u don't want accelerator pump, which I find off little use,
then u can have it for 16.99 all in.
that said I'd send u mine for the cost of shipping... Im running a D slide type carb now...

They are pretty much the same bike. IIRC, Dong Fang make them both. The hiest just gets a little more detail paid to it. I'm not sure what you mean by the fork racks. There is, or was, a Heist thread on here. You'll have to try a search for it.

Re: Dong Fang DF 250 RTB Bobber Information
It looks like the heist has a more raked look more chopper like look know what I mean? Thanks for answering my questions I say there the same bike basically and the dong fang is more than a thousand dollars cheaper I'm all about that!! do you know of a list of dealers here in the states?

People have been having some luck with PSM. http://www.powersportsmax.com/index.php/cPath/482_483
There is a thread on www.chinariders.net about good and bad drop shippers. There are no true dealers in the US. Only some that set up and sale as a retailer.

Re: Dong Fang DF 250 RTB Bobber Information
I really wish someone would wake up and start selling replacement engines for these bikes. My new motor still runs fine, but it was not easy to come by.I got lucky locating it. If they sell the bike, they should offer parts as well... including engines. Just saying.

what u really want is a 400cc - 500cc with a cg footprint I wish someone would wake up and produce that.
you can actually find the cg250 just not always if ever in Black.
I've replaced the head twice and cylinder once, both times I had to do the paint.

Yes very hard. Or at least that is what it has been for me.Now granted I am not familiar with all the ins and outs of the motor only from what I have been given as far as information here. But yes I got real lucky some guy was selling parts from a crotch rocket bike,that happened to use the same ( almost the same) engine.I had to fabricate a bit of motor mounts as the footprint was NOT identical.But she runs great.Just have an aggravating vibration at 45 to 50 throughout the bike.
I would love to bump her up just a little in cc"s but not much.I do not feel the brakes would handle anything bigger. Maybe an actual 250cc instead of the claimed 250 this motor is supposed to be. It is actually just a 229cc I think.
But someone needs to wake up out there and do something. But I guess this bike is just a go between or something. I would not have any issues with a new replacement Black actual DongFang motor for this bike. exact footprint and everything.

if your a casual consumer then yes, you can't go to your local shop or garage and get any help in finding one let alone installing it.
but I've come across a handful of sites online that claim to have them readily available, and they are almost always available on eBay as well.
but like I said what's really hard is to find it in stock black.
but if I were to shell out what they are usually asking, I'd rather put that towards an upgrade

exactly what engine did you put in?
when u get the time please take a shot of the ID plate, should be near the gear shift I believe.
and how about the motor mount you needed to make.

I'm interested to see that too. I believe that those two rear engine mounts are the same on all those CG and CB clones, and the only difference in engine mounts pattern can be in the front end (engine with or without balancing shaft, etc.).

Re: Dong Fang DF 250 RTB Bobber Information
735 bucks for one of the cheapest engines you can find on Chinese market - that's not awesome. Those CG clones, as much as I know, cost in China (factories offer them to wholesellers) for less than 200 bucks. I can understand if local dealer, fifth-sixt-seventh in the chain, offer this engine for up to 500 bucks MAX, but IMO, 735 is a robbery.

I agree but in order to get the good price you usually have to order ten or more and run the risk of the engines not being EPA approved. If not EPA then they will be destroyed by US Customs.
I imported a Chinese jeep years ago and it was EPA approved and still cost me over $200 in custom fees to get it out of the port of Miami Florida plus several long drives.

Make sure the engine is EPA approved and add shipping plus custom fees.

Re: Dong Fang DF 250 RTB Bobber Information
i would hate to go from a 67mm piston down to 65 fearing even less power ... but this is why it's a hard find.
but throw enough money at anything it's no longer a problem I guess.
that said I've seen genuine 167fmm (in gray) for under 500$ sold from within the US, I'll try to scare up the link.
zorge is right for 750 its not really solving the problem.
for that I'd invest the time and a few more dollars and see to fit one of these with a similar engine mount pattern
http://www.ebay.com/itm/262029549770
4 valve ohc engines, likely has twice the power
hey zorge what this engine a clone of?
some Honda I think...

That is the water cooled engine that CSC uses in the RX3. It seems like a solid engine. I'm not sure if it's a clone of any one engine. It seems like a culmination of several.

it's used by few companies, maybe many but that's irrelevant, main point it's a Japanese clone of the honda nx250. knowing that we can realize there are big bore kits available for it, which is huge and why I pointed this particular engine out.. 25hp stock, who knows what a big bore would give.
but i was hoping zorge would chime in with some hard facts..
fwiw anything without fins is a pretty safe bet to be water cooled

I think it is pricey, but comparing to this CG clone for 735... The devil was not so black as he was painted.

Note that RX3's engine is SOHC, while this one is obviously DOHC. In my book, that is enough to say that those are two different engines.

Some time ago, I saw on "Alibaba" that some factory (I don't remember which particularly) offers soft enduro with the a-la "Honda" XRE 300 design, fitted with this NX clone, but with 270 cc or something similiar. Are they got those ccs by using biger bore cylinder or crank with longer stroke, I don't know.
Meh... IMO. extra 20 ccs on current 250 isn't something which will make wonders.

If I could pick it up and the case turned smooth then no problem, the rest can be fixed. but not in the mail with no warranty.
that said that guy has been selling these motor for months..
he finally listed them individually but before he just has a pic of about 10 in a box only listing them as 'probably 200cc'. and for like $250 (plus shipping) each...
but I knew exactly what that black one was and where it was from, and even at that price if I ever needed a entire engine, i decided my money would be better placed elsewhere
