    Re: Dong Fang DF250RTD (Cafe Racer)

    So the DF arrived today, amid snowfall here in northern Virginia. Based on the bill of lading it seems that Belmonte bikes is a drop-shipper, as are most online China-bike companies. The bike looks...

    Dong Fang DF250RTD (Cafe Racer)

    Greetings all!

    I've decided to get into Chinamotoing. I've ordered a DF250RTD from Belmonte Bikes after searching for a drop-shipper with decent feedback for this version of the bike. The new...

    Re: Dong Fang DF 250 RTB Bobber Information

    So I've cleaned out my pilot jet, and now I'm getting ready to re-install it. I took out the mixture screw, and have forgotten the order in which the washer/o-ring and spring should go in. Does...

    Re: Dong Fang DF 250 RTB Bobber Information

    Does anyone know where to get pilot jets for the Deni/Denki PZ30 carbs? I can't get my bike to idle without the mixture screw backed out a good bit (maybe 5 turns or so) and according to most tuning...

    Re: Dong Fang DF 250 RTB Bobber Information

    Just a quick heads-up to you DF owners,

    I posted some time ago on changing out the stock coil for one of the orange "performance" coils from Amazon. As it turns out, the coil was the cause of my...

    Re: Headlight Switch

    I think it might be some sort of wiring issue. If I start the bike, and use the killswitch to stop the engine, the speedo still wont register until I unplug the speed sensor cable, or turn the bike...

    Re: Battery Failures

    Found a possible cause. The speedo will work with the engine off, however, when the engine is running the needle won't budge one bit. Clutch adjustment, maybe? I used an electric drill with a...

    Re: Battery Failures

    I haven't gotten too in-depth with troubleshooting yet, BUT, the cable appears to be an electrical-sensor type and not a mechanical speedo, as one end goes to a 3-wire connector.

    So I finally got the DF out on its first street ride, and the damn speedometer isn't working. It's getting power, both to the LCD display and to the turn/headlight indicators, but the speedometer...

    Got the DF fired up again tonight. I spent about 45 minutes tracing wiring with my multimeter, nothing seems out of place or damaged, although I did reposition some wiring under the tank....

    I haven't had the chance to swap out the jets or coil, as I've been swamped with work and with schooling. The weather also hasn't helped, but first bit of clear weather I get I'll set about adjusting...

    40 with no washers is correct. You should check the videos of the Colortune, if you haven't seen it before. I thought they had gone out of production, but they can be had online from the UK for...

    I've got a removable baffle in mine as well, and it did seem to help a bit with the top end. I cleaned the plug yesterday and fiddled with the mix screw since it was warm out. Got the plug to a nice...

    Re: Dong Fang DF 250 RTB Bobber Information

    I've ordered a rebuild kit for the PZ30 carb, it comes with everything to include the mixture screw (which I may have turned in too far and damaged) along with pilot/main jets. No word on jet size,...

    Re: Dong Fang DF 250 RTB Bobber Information

    Seeing as how they put in a incorrect amperage fuse, it's entirely possible that the carb was intended for something needing a larger main jet (maybe a DF250RTC, or ATV?) I'm certain that the 167FMM...

    Re: Dong Fang DF 250 RTB Bobber Information

    It's an unmolested 2010, not a 2012. I purchased it in early 2012, but the bike's frame tag, and the title both show it as a 2010. I might hit some of the local motorcycle stores and look into a...

    Barnone,

    It still coughs while warm, mostly at speeds below 20mph, in first/second gear. No washer under the needle, and the jet size should be accurate, I read it off of the jets, and the bike...

    I've got a 40 pilot 105 main jet setup, but that's what the bike came with from the factory. I've adjusted the float height to 15mm, lowering the fuel level about 1mm more than the Walbro...

    The sputtering wouldn't be hard to ignore if it wasn't for the fact that it occurs at low speeds, which can make cornering difficult or downright dangerous depending on the situation. I'm considering...
