Dong Fang DF 250 RTB Bobber Information

[Bobthebobber]

@ 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
