I have a 2012 DF RTB 250 (Heist) As well. However mine will not go above 40 mph at its fastest. When I bought it the owner told me that it had some sort of speed limiter/ speed restriction on it. I was wondering if anyone might be able to help me remove this or knows anything about this subject?
Have your read through this thread? The DF250RTB is not called the Heist. There is a different thread on this site for the Heist.Quote:

There is no speed limiter/speed restriction on the DF250RTB engine however if your bike is a DF250RTB has your rear sprocket been been changed to a smaller one? The stock one is a 45 tooth one and most of the DF250RTB owners here go to a 35 or 32 tooth one. The stock gearing is way too low.
I have a Dong Fang 250 RTB-B with the apehanger handlebars. I am not sure what size sprocket is on it currently, I have not changed anything on it since I got it. Would the sprockets explain why it will not achieve any faster speed than 40 mph? Attachment 16972
Count the teeth on the rear sprocket.
Yes, the stock gearing is way too low. With a 35 tooth you should be able to run 50 to 55 MPH.
You probably want a JTR279-35 sprocket.

Where can I get the 32 tooth sprocket?
Did you have to cut off some chain links to go with that sprocket? Does the stock chain have a master link, or is it an endless chain?
I have the same question about the chain length fitting the smaller sprocket. My chain has a master link so it should be a problem getting it off
Change the part number to JTR279-32Quote:

Seem to remember that I had to take some links off. It is a master link chain. Get some 520 chain master link repair kits in case you screw up.:lol8:Quote:

Likewise some that we have at our place here in town. Our new grandson is not impressed with the heifers.
Is this dongfang? Finally avaible in Poland.

That is a CCW Heist and not a Dong Fang but it is a very similar motorcycle.Quote:

my df250 carb is running full force and the idle screw does not do anything. Any suggestions would be appreciated. thanks
I took it apart and cleaned it with gum out. Could the accelerator pump be stuck?
The idle screw turned clockwise slows the engine normally?
This is just a stretch, but it happened on mine... Check where the throttle cable enters the hand grip area. Mine got pulled out a ways, and then stuck out. It made the motor run at WOT. All I had to do was pull it out a little further and re-seat it back into the opening.

Our PZ30 is like the PZ26 in the pdf.
Thank you and I will check that next. I think i did put the slide in incorrectly when reassembling it. I'll let you know how it works out.
Don't ask me how I know!Quote:

Internet speed claims cannot be trusted IMHO.
Don't know about anyone running 75 MPH on the 2012 DR250RTB on a level run, very doubtful that can be achieved without an engine swap to a bigger displacement motor or maybe very extensive mods to the existing engine like a turbo charger. This Honda close engine started out as a CG125 cc engine.
Just not a lot of HP out of the 229 cc push rod engines.
My DF is in the mountains of Western North Carolina and I am in Southwest Florida for another months so I haven't ridden her for six months but I seem to remember that I got her up to 55 plus a bit MPH GPS with just the rear sprocket change to a 35 tooth. The carb comes pretty well jetted on the 2012 DFs. A reasonable cruise speed would be 50 MPH.
Thank you very much for the tip. Everything running perfectly . The slide was not lined up with pin correctly. My throttle felt weird and funky. Now the throttle feels normal when I twist it. She purs like brand new now.
Thank you very much again!
DantheMan claimed it, Gardo claimed it, and even made bogus videos of exceeding it.Quote:

if u did have a heist, i also confirmed there is a big bore top end they sell for like a zillion dollars...
but as ive found on rebuilding my ls650, more power comes from the increased compression of the domed piston, then maximizing the bore from 94 to 97mm.
So Ive decked my cylinder head on this DF 167fmm from 9.0 to 10.0. Before which, the best speed i could achieve was around 60mph indicated on the 10% overzealous OEM speedo, so that was perhaps 55mph real at best.
After the deck i gained a mild yet noticeable amount of power, likely can cruise on a flat at 60 true and hold it.
I was ready to ditch the engine and this bike altogether. but the power gain got me to the point that on a long mild incline, where i might before lose momentum down to say 45mph.... brutal as the cars piled up behind me id often pullover to let them by....
but now i can maintain my speed at the state limit of 55 through out. world of difference
I bought a 30 tooth as i believe I may now have the torque to make it workable. its the smallest available i believe
http://clevelandspeedshop.com/collec...ton-gasket-kit
$419.95
Bore 69.5mm - Stroke 65mm = approximate 247 cc
Stock is 67mm x 65 = approx. 229 cc
gain in displacement is about 18 cc
Maybe there is an increase in compression ratio.
Swap in a 250cc 2 stroke and go easy on the oil mix to cut down on smoke.That should hold 60 on the highway.Can't do it in a state or country with inspection laws.
i can attest as soon as you start considering motor swaps, you start considering bike swaps.Quote:

A. information on guaranteeing one of the other cg or cb engine clones are a bolt in replacement is scarce. You will need your motor in hand and measure.
B. then you also need to acquire the pipe, carb, so on and so-forth. Which is not usually not worth the price on a $2k bike.
Then as i mention, you start realizing if your willing to do the mods for motor swap above, its not a far to stretch to mod a lightly used Japanese cruisers which can be had at similar prices.
Been down all of these paths.
Truth be told if looking to just maintain speed, turns out for me at least, decking the head was the least amount of time, work, money.
Got a video of it here. 5 minutes of my life.
Sounds strange now that i think about it, a simple head deck...
