I did not want to ride a scooter any more, and when I saw it on scooter depot it was the right fit for me. I am proud to say that my 2010 DF has never given me any troubles other than small set backs,which I hear are also the types of things that occur on many higher dollar bikes. I have just under 10,000 miles on it, I ride daily, rain or shine. (It is my go to ride to work, and sometimes it may be raining when I leave...but I gotta get home now don't I)
As for the items that have given me issues, they were nothing that were costly, and easily replaced for better quality products.The motor has been great, although I am due for an oil change. In fact I have yet to replace the spark plug. Yes that is correct, it is the original spark plug the bike came with from the factory. I see no need to replace it if it isn't broke. My bike is not a beauty queen, I am more of a rat bike kinda guy. so no fancy chrome, no fancy paint, nothing extra that I do not need.I do like what a lot of people have done to their bikes, but not for me.
I changed the sprocket to a 35 tooth, I added a set of saddle bags( with my own bracket to hold them on). The headlight was changed out for an auto mobile headlight. The handle bars were changed to mini apes for my comfort. and she runs and goes just like the first day I got her. For the money she is what she is. and I think she has paid me back with the cost savings at least twice now.
Just working out the details to replace the cush bushings( thanks axa for the terminology) gonna look more into that this weekend at a Honda dealership.
On that note I have measured them, they are 7/8" deep and about 1" wide. The part number 41241-307-010 I found looks to be the same, but I have yet to see one in person and hesitate to order offline. I will find out this weekend if the dealer has any. fingers crossed.
Best bang for the buck this bike is. I recommend it anyone and everyone that looks at her.
Thanks for the info.
Anyone knows a SoCal dealers that sells these kind of bike on a decent price.
Another thing, are these California legal bike? With the strict California regulations, will soon going back to horses. lol
Thanks

@ barnone.. I cured my cutting out problem after all the switching of the jets i did. Its running stock jets now with the closed ended filter and a little less than 2.5 turns out on the adjustment. No more cutting out.. I did mess with the accelerator pump though also.
Anyway i went to lowes today and picked up this stuff. I decided to spend a little more and get the joint-less coupler to keep it all chrome and not have the black rubber coupler. (im not using this filter with the ram.. it was just for the pic.. Ii will be running the stock filter until my new one arrives in the mail)
Im thinking I will mount it facing the left side so that it will not be taking in any exhaust heat
total cost on this was about 14 dollars

i found this filter on ebay for 9 bucks from china.. it looks just like the stock filter with the open end. (2012 filter has the little knob sticking through it where the crank was vented.. I have plugged the knob.. id rather replace to delete it all together). This will be used for the ram air setup,

I know Chi tried that reverse cone filter and it didnt work well as it forced too much air.
any thoughts on something like this being better than the stock filter? Maybe Caulk off the back side so that the air is forced inside and doesnt pass through and out the back of the shield?

I could probably make something like this using my existing filter and a big plastic cup.. but this might just be more restrictive than having no funnel around the filter.. any thoughts?? I could easily make some sort of scoop.. but not sure if it would be beneficial or not.. and then of course there would be extra drag.. and with a motor this small it might do more harm than good at 50+mph

After hours of searching tonight I think i finally found what we are looking for to use with the ram air setup

Re: Dong Fang DF 250 RTB Bobber Information
It sounds to me like the carb is unable to flow enough air with a filter on there.I would try a velocity stack and facing the carb vent tube toward the front of the bike.

You can get the Clevland CycelWerks Heist, its almost the same bike but they tack on 50% for their 'troubles'...
May well be worth it for you.

Does it give you too much air? The stock filter is apparently restrictive enough to prevent this...
By the way, you'll be able to butt that p-trap right up against the carb and minimize the size of the couple to about an inch, then the rubber black is at a minimum.
That said, the black on our matte bikes don't look so bad

But I think you may have found the right idea with that red cap with the holes in it, if your getting too much air with an unrestricted ram, then you can cap it and add holes until you find the right balance...
That said, you may just want to try the stock filter with the p-trap first, works for me...
