Dong Fang DF 250 RTB Bobber Information

[DanDaMan]

imo u need to plate the air injection if removed , if the air pumps not forcing air into the opening , the motor will force exhaust out the air injection inlet super heating the hose or rubber plug , and remember if u raise the fender , the bottom of the fender (below the seat) will inch towards the tire as well

That sounds like the problem axa was having with his pump. I'm thinking when Bobthebobber painted his fender he my have inadvertently moved things around and lost the clearance under the rear of the fender. Probably have to loosen the one lower fender bolt too so you can adjust the fender for clearance and then tighten down all five bolts.

I'm going to make the plate and remove all the plumbing like I did on my old DF.

Use the removed piece as a pattern to make the plate out of 1/8" or so aluminum plate. Paint it black. Put a cap on the vacuum port. Easy peasy.

On my old DF then I moved the ignition key switch to the place were the pump was. Kinda cleaned it up a bit. I don't know if this will work on the new model.

any chance you could make an extra and send it out this way for a little $?

After reading Bobthebobbers problem I checked the clearance on the tail on mine and there was a half inch. Barnone, I hope they send a different manual than they sent with my bike as it is almost useless. I hope you kept the manual from your 2010. I'd like to get a copy of that.

Unfortunately I did not keep the old manual but it wasn't that great anyway. It was better than what I am hearing about the new one.

well I'd check everything if I i were you, i did.
but the only 2 issues I had was my secondary air pump was not functioning correctly, blowing it's hoses. a non issue as the entire system is gone.

the only pressing issue I had was absolutely no clearance on the valves, there was even tension on mine.
I find everyone who checks their valves reporting they are at least tight.

axa,
Good info and added to my to do list. The chain along with the valves were very tight on my 2010 DF.

PM me.

My DF arrived today and I met the delivery truck in town and transferred it to my truck. No way could he have gotten up my steep driveway. Very little clearance between the rear wheel and the tail light wiring so that is the first thing to fix.
She looks good.

Looks like I can increase the clearance between the tire and tail light wiring by putting a spacer here. That will move the bottom of the rear fender aft and therefore raise the rear of the fender. I already put in a small spacer but need to get a longer bolt tomorrow for a longer spacer.

This thread is kinda all over the place as long as it has to do with one the 250 OHV Bobbers whether a CCW Heist or a DF 250 China girl. That being said, What positive effect does taking this EGR tube or what ever is out and covering the hole with a plate ? Is it just to simplify the engine bay and clean up the looks ?

Should make the engine run a little cooler, reduce popping on deceleration, but otherwise just cleans things up a bit as you mentioned.
This thread is about the DF not the Heist. There is a separate thread for it.
BTW, the CCW Heist a also a China girl.
