yea i tried that screw I think. It's a flat head with a spring on it. You have to stick the screwdriver through a hole in the throttle to access it. I gave it a few turns and nothing happened.. which lead me to believe that it was the mixture screw. With my experience with carbs of this style.. the idle screw has always literally been a stop screw on the throttle lever that would literally manually adjust the throttle.

"Can you show me where the idle adjustment is? I fired it up last night and it seemed like it was running about half throttle. I could not for the life of me find it in the dark."

Bob the bobber, the Idle adjustment is on the side. On mine you have to stick a small screw driver through the the throttle control lever. Make sure your throttle cable is functioning correctly and has a full range of play and that it is closing all the way with just a tad of end play. The manual they sent should tell you in a Chinese sort of way how to do this.

Most likely the flat black is the same paint they use to paint the frame. Probably furnace paint ( bar-b-que black ). The tank comes off easy on the 2012 four threaded bolts. Tighten them down just snug to the rubber grommets when reinstalling.

My chain was tight when it came. Maybe a 1/4 inch play with no adjustment in. I've put 25 miles on it since I got it and it has loosened to about 3/8th with no apparent damage.

There is a instruction manual for the carb in this forum 10 or so pages back. If you have enabled private messaging I will send it to you.

The chain is DANGEROUSLY over tightened; mechanically speaking. If a person was to stand on it and bounce, the chain would not move the slightest bit. It almost seems like it is 3 links shorter than it should be.. although you are right.. it may get away with putting on the 35 tooth and not having to take links out. Im not sure I will even be able to remove the master link because of all the tension.

Hey Guys! I got my bike this weekend. Everything looks just as it should.. minus a few small problems. The chain is SO TIGHT i do not even want to roll the bike around in fear it will damage the sprockets. The weird thing is that the tire is already adjusted at the most forward setting.. leaving to way to adjust the chain and loosen it. Good thing I have a small sprocket on the way. The grease fitting on the left foot peg was drilled on the top instead of on the bottom.. kinda silly but i just threw some flat paint on it and you dont really notice. There were a few other minor things like paint chips and such.. but i worked most of it out.


I pulled all the stripes off, changed the air filter to a slightly shorter one with a closed end, and swapped out the breather to a matching mini cone filter. IDK how it was on your bikes but the battery took me almost an hour to get in because it was VERY very hard to get the nuts and bolts through on the terminals.

Worst thing happened though.. when i was putting gas in her.. the top of my gas can was cross threaded and it poured all down my tank... it ate all the paint on the tank and now I have a streaked tank. It actually took the paint all the way off in a few spots. Really sucks.. I actually like the flat black in person.. I guess ill have to repaint it eventually.

Can you show me where the idle adjustment is? I fired it up last night and it seemed like it was running about half throttle. I could not for the life of me find it in the dark. Man this thing is loud.

Here are some pix of the the bike after a fresh wax, and prior to the gas tank fiasco. You can also see the changes I made with the new air filter and breather, as well as the grease fitting that sticks up into my foot on the left side :p

Yeah that's on my to-do list as well this year. Hope she is still making them once I have the money. Damn rubber tire cover is starting to weather and dissintegrate now.

Yep, chain was tight on mine. Should be 1/2 to 1inch slack. I recently had to tighten mine a bit as it was too slack after only 360 miles. Watch that.

I did spill gass on my tank as well but it really didnt hurt my tank. A year later the clearcoat they used on the fender started coming off on the fenders but not the tank. I still have the stupid blue protective film on my gas cap and am having a hard time getting that crap off. I just use my fingernails redneck style to peel it off a bit at a time. Was goint to use a wire brush on a drill to get rid of it but thought that would ruin the chrome finish. Oh and dont let the chrome plating fool you. It still will rust as I am fidning out.

Air filter swap is a good idea IMHO. The stock one lets too much crap in. The end cap filter is a good idea as the stock one has no filter media on the tip, its just wire and wire mesh is not a good filter media. Next time Im going with an all phoam one personally. I like the cool retro wire mesh looking one but I prefer something that will protect my jap clone carb.

I remember my brother telling me I needed to adjust the seat height/tension but I do not see any kind of adjustment nut there. Am I wrong?

Changed my 88 jet to 105 today. Vast improvement, smoother and pulls better.

New to the forum here. Saw the bobber (Dong Fang) and immediately loved it, however I have heard some... discouraging things about the bike.

I am reading this thread in as much as I can but still begs the question: Get one or not? I see there are a lot of needed mods to be made and a lot of things to check or be aware of, but overall -- scale 1 - 10, would you recommend it (1 is hell no, 10 is hell yea)?

I will be reading further. thanks.
