It's a DF250RTB. Sorry but there is no need for me to call you.
I got my bike from a different but screwed up outfit.
Meh redacted. Not worth it :pQuote:

Figure 10-15 days to get to you're door from the time they ship it out, then tack on another 3-5 days for the MSO at the very least.
I placed my order from countyimports and it says the order is completed but still not tracking #, and that was 3 days ago (I placed the order about 6 days ago). I'm not sweating it and I'm sure they will ship it out when they can. So just sit back relax and start getting ready for when you're bike arrives.
Also have they charged you're credit card yet?
If you don't have that bike in your hands in 3+ weeks after your order and they charged you're card just do a charge back and order it from somewhere else.
Ahh the DF250cha Nice looking 3/4 chopper. OK Chuck here's my take. Relax take a breath From what I read on this chopper its got the Same engine as the DF250RTB and similar frame. Now I bought from Scooterdepot their Customer Service sucks but the get the job done. Remember they are in CA which is 3hrs behind the East Coast when you call expect to be on hold for 20+ minutes. The folks are nice and will try to help, if wotask for a manager.Quote:

As far as the shipping is concerned I also had to take a day from work I freight companies have the hours that they do business, just the way it is.
oh from ordering the bike to getting my MSO took 15 days
So I have been playing with the gear ratios and the sprocket setup that I'll wind up going.
Here are the exact ratios for these motors.
you can get the speed calculations here http://www.bikerenews.com/Stories_Ar...Calculator.htm
Also I believe these are the sprockets we need, but thats only if it is a 520 chain: http://www.jtsprockets.com/52.0.html...el_uid=4657&p=
Just plug in all of this info:
Max RPM: 8000
Tire Size: 140/70/18
Primary Drive Ratio: 3.333
Final Drive Ratio: 13/45 (I will have a 13/35)
1st Gear Ratio: 2.9.9/1
2st Gear Ratio: 1.867/1
3rd Gear Ratio: 1.389/1
4th Gear Ratio: 1.150/1
5th Gear Ratio: 0.9545/1
With this ratio top speed in 5th gear at 8000 rpm should be 53 mph. (the manual says max hp 11Kw @6500RPM)
I figure it will more likely be 78-81 mph (this doesn't seem right at all from what all the dealers claim a top speed of 75mph).
Also I don't see these motors sustaining 8000 rpm for long periods of time so figure you'll be cursing at around 5500-6500 rpm.
Aboshi,
Good information on the sprockets and gearing.
So with a 13/40 71MPH at 8k RPM stock
So with a 14/40 77MPH at 8k RPM
So with a 14/38 81MPH at 8k RPM
So with a 13/35 82MPH at 8k RPM
Thanks
I don't understand how those speed calculators work if they don't take into account the size of the chain and sprockets. A 428 chain and sprocket setup running 13/40 is not the same as a 520 / 525 / 530 setup running 13/40. Seems to me there's a calculation factor missing ??? :confused1:
Cheers!

Its generalized, it doesn't matter the chain or motor size. It is usually pretty accurate though.

The 13 tooth sprocket has to turn 3.08 times to get the 40 tooth sprocket to turn one time.
It is worth a bit of thought. Confuses me too though because I forgot all my tech school science! So ... one turn of the sprocket with a certain size tyre will travel a certain distance, I can see that. So where does power come into it? Just faster acceleration and carry more weight? But bigger engines don't usually rev any more than small. And if power applied does have anything to do with it the width of chain and sprocket would make a difference, so would width of tyre. Ah damn, now I've got a headache!

thanks to jape.
Well after 3 hrs at my local DMV I got told that I need to get the bike registered at the home office at my state capital in Trenton. Gotta love local bureaucratic BS even though I had all the proper paperwork and information that they asked for. the saga continues
Gordo,
That's a bummer. Does not make sense to me to have to go to the state capital DMV office just to register the bike. Florida did not have the manufacturer's name in their database so I was worried about that but they got it added. State capital of Florida is an eight hour drive for me.
I'm heading to a bike night down town in Fort Myers,FL later this evening to check out the bikes and ladies.
Gordo:
They had to be jerking you around somehow, I know there is no way in hell I would drive to my states head DMV to get anything titled. I would call them up asap and find out why on earth they are going to make you travel a few hours away.
They have to be connected by computer to head office, they are just incompetent, get on to your local politicians. If they are worried about 'names' for registration, check the emissions plate, the 'engine type' number will give you all the EPA details which should satisfy the idiots. I don't know if the details on a copy of barnone's would assist by showing them it is legally registered elsewhere? Maybe they just don't know which boxes to tick?
i.e. on the TMEC 200 in another thread, I can see the plate and it shows engine type 9TMPC 196TPI
http://www.epa.gov/otaq/cert/veh-cer...r-02-01-10.csv
and from that you get certification for importer and manufacturer
I think MJH pointed out this or a similar link early on, just noticed a credit where it is due ...

I remember someone on Chinariders a few years back from 'Jersey getting tags for one of the 200cc enduros. He did have a few hoops to jump through, but it happened. However, it was several years ago, and at one point, one could get some of the 200cc enduros registered in California depending on which DMV office they went to. That has since changed. But if the Dong Fang is DOT, I think that means it is 49 state legal to be registered. You might be the first one in the state to register the bike (if I remember, that might have been the same situation with the guy on Chinariders). Good luck, but I do think you just have a technicality hoop to jump through.
Yup even the spreadsheet with me, but they wouldn't hear it and at that point my politeness started to wane so I smiled said thank you and walked out.
I'll give them a call on Monday and see if i can hit the regional office 2 towns out and get it squared away. Need to check the weather and see if I can "work from Home" on monday
Good luck with the reg.Quote:

Thanks to Gardo and Barnone for keeping us informed of their adventures with this Dong Fang bobber, sounds like a good bike for the price. I like the less raked out front end and the seat looks like it's right off of an old BMW R27, very unique looks. I'm looking for a replacement for my ancient 2stroke scrambler, I'll be watching the Dong Fang with much interest!:thumbsup:
Gordo,
The popping is from a too lean condition which is a common problem with EPA bikes.
From post #168
Results: The bike pulls better and revs higher. Was stumbling at high RPM before change.
Stock main is a 88. I used a 100 for the first try. Also have a 105 and a 110 maybe to try.
Stock pilot (low speed) is a 40.
Jets from http://www.jetsrus.com/a_jets_by_car...4-36_main.html
Also I installed two washers under the needle that helps the mid range.
Three washers were too much.
Bike pulls much better now and almost no popping.
Still waiting for the 14 tooth front sprocket which should fix the getting across the intersection without shifting to second gear issue. If the sprocket is too big then smaller rear is the cure as suggested by Aboshi.
The above is about what I had to do to my other bikes to solve the lean and gearing issues.
Here are a fe more things I am going to order today.
set of 10 jets http://cgi.ebay.com/ebaymotors/ws/eB...#ht_2600wt_935
Also you guys might want to get a new CDI to hep with the mid/top end:
http://cgi.ebay.com/ebaymotors/Racin...#ht_1358wt_897
or
http://cgi.ebay.com/ebaymotors/Racin...#ht_1358wt_897
Also you should remove the crap sparkplug it came with and go get a NGK
It sounds like we should have a 105-110 main jet in there, but might not if the CDI and NGK help out.
I was also thinking of a better coil as well, either one of the cheap chinese ones on ebay or a very good one from http://www.nologyhotwires.com/
from nology search for 152-001-060T we would need the single spark plug wire one for $69.99
Im not sure if the chinese coils would be any better then the stock on that comes with the bike to begin with, so I would say stick with nology if your going to do this upgrade. I also found twin tec coild pretty cheap http://www.jpcycles.com/product/382-...utm_medium=cse
All single fire coils should work for any of these single cylinder clones. And I'm sure it would be a very big improvement in the performance for these engines when using the aftermarket CDI.

Do you have access to a dyno for tuning? I would like to see what each change does as far as rear wheel HP improvements.
How did you come up with the 105 or 110 main jet? I am currently running a 100 over the stock 88 and it took out the stumbling at high RPM. I have a 105 and 110 that I could try. I really ought to take the bike over to a local shop that has a dyno to try out these changes.
Think I will order the CDI after I check the one on the bike and compare the plugs.
Thanks
I can ask a friend to see if he will let me use the one at the shop he works at on the weekends but I wouldn't hold my breath. If I was down in FL it would be a different story...
As for the jetting if your stumbling is gone with the 100 then you should be fine.
Every motor will react different when it comes to jetting, especially with temperature/altitude/humidity
I forgot to ask a while ago about the transmission on these bikes.
Is is 1 down 4 up or is it 5 down like on most china clones?
I ask because I cant stand the 5 down shifting It confuses the hell out of me and just doesn't feel right what so ever.
Trans is 1 down and then 4 up.
That makes me very happy!
I have to call countyimports today and see if they have my tracking #
Their email server sux badly and I get the emails a day or two later, and trying to contact them I am on hold for 20-40 mins...
I placed the order on the 3rd so I should have heard something by now as far as tracking because I saw they charged my card a few days ago.
Aboshi - how did it go any tracking info yet?
Hi, I am just joining today after reading this thread. I am very serious about trying to get this bobber. I need to sell my snowmobile and trailer first though. This will be my first bike and I am really only getting one for the gas mileage and cruising here and there. Has anybody got it up to 55, and what to get for mileage doing cruising. Thanks, anyone want a snowmobile and trailer lol.
bckcntryclddr welcome to the boards - tell us a bit about yourself.Quote:

I would suggest checking out your local DMV website about registering a vehicle with an MSO/MCO, since you are in NH the live free or die state it may be easier than NJ, the live under our bureaucracy and drown state.
Again welcome aboard and where were you in Dec 2010 when we were buried under 30 inches of snow LOL
