Dong Fang DF 250 RTB Bobber Information

[GonzoX]

I admit that p trap looks a lot sharper than my U bend radiator hose :p

and the faster u go the better it works 50-55 negligible , near 70 noticeable improvement

but to get that kinda speed youd need bigger front sprocket , meaning a chain change

u can fit a 17 tooth front with 428 HD chain

and remember , a bit lean provides better power

I agree, the p trap looks a lot better and doesnt look like it will get in your way while riding. And with the stock filter with no filter media on the tip end I think it will get the air ram effect at speed.

But Im a type A personality myself and hate the stock filter. To me a filter should do just that, filter the air and keep the crap out of the carb. Dirty carbs are a royal PITA to fix and are hard to diagnose when they cause a problem so Im the kind of guy who wants absolutely clean air going into the carb. That's two things I dont skimp on with any of my vehicles, oil and filter media. One ouce of prevention prevents a pound of pain later.
