Dong Fang DF 250 RTB Bobber Information

https://youtu.be/pWIdxRNB62g



I found this on you tube.

very cool I posted to it about how great my bike has been for me. Thanks for the link.

Well i had changed out the head gasket, and she has been doing well since.But I feel i am having issues with it again.I have had a couple hard starts the last week. It would turn over but just not actually start,then all of a sudden catch. and I noticed a bit of black smoke exiting aound the front of the motor.At first it appears to be the exhaust pipe, but it is tight and has a gasket on it. I will check it again after work,but I feel I may be leading to a head gasket issue again.
So My question, I torque the bolts to 21 lbs as suggested. Can the gasket go bad this fast?I did the work on it 3 month ago? ( check this post for 5-5-16)
Just looking for a quick what if from anyone? Thanks.

Had been real busy with work and hadn't had a chance to ride in 3 months or so. Hopped on yesterday and went to stop at a stop sign and no rear brake!! Pedal goes straight to the stop. First thing I did was check the fluid, which was full. Second thing I did was search this forum. Hopefully I just have air in the line. Questions about ben2go's post above: How high do I need to lift the rear? Best way to lift the rear? Thanks in advance!

Not very high.An old milk crate,or something similar, under the frame would work.I have a cheap $70 Harbor Freight moto lift jack.An invaluable tool,but I work on all kinds of motos pretty often.

Looks like http://www.saferwholesale.com/250cc-...43JRoCFBnw_wcB

If it is blowing out head gaskets you need to check the head for flatness.
Watch this video.https://www.youtube.com/watch?v=HyKN52HD6RU

FYI--Superior is showing they have the new 2016 models. Good to see the 2016 models listed on the EPA certification list so you guys with a few year old Dongfang bobbers and dirtbikes aren't stuck with 'orphan' bikes.

NO CARB (This unit is not for sale in the state of CA or PA)
For California customer please check our California Legal Section for CA DMV registerable bikes

Or Connecticut and any other state that requires C.A.R.B. certification.

So NOTHING has changed since the first 2010 models.
