#6221 Re: Dong Fang DF 250 RTB Bobber Information12-03-2017, 06:55 PM
Folks, was wondering if anyone could throw out the axle size of the front wheel? (i.e. 12mm?) I am doing research on the speedometer drive gear assembly.
I have a loud clanking in the front end, had to coast with power off to hear it correctly, I then detached the cable and rode a bit and seems to be something with this gear assembly. Not 100% at this time, still a bit more checking to do. Unfortunately the weather is a bit off today, and on the jack cannot bring her to speed by hand to hear anything. Anyway. Axle size anyone??? 12mm, 15mm thanks.

Check your spokes and make sure they are tight. If you hit them lightly with a 15mm wrench, they should ring. If they have a thud, check the tightness. They don't require much torque, but they need even torque all around or the loose spokes will click as the wheel rolls with weight on it. I check my V Star regularly by coasting downhill with the engine off. If I hear clicks, I check my spokes and every time there's one or two that are lose.

12-06-2017, 04:39 AMDO NOT JUST TIGHTEN YOUR LOOSE SPOKES! Your rim needs to be true! If u tighten only one side and wonder why your hopping up and down on your seat then look at your rim! You either need to buy the right tools to do it or just take it to a shop! It's not that easy just banging a wrench on them and tightening them till they ring! You will destroy your rim and possibly break spokes! Do not get back on here and start complaining that your dong fang is junk because you decided to listen to someone that obviously has no clue really what they are doing! When I first read about someone saying tighten your spokes I about died thinking of all the clowns gonna be mad when they can't ride!

12-06-2017, 06:13 PMMy 2016 DF actually has the CB250 OHC 165FMM which "supposedly" makes more power (cam & higher compression) than the CG250 167fmm. I am surprised...with a 38T sprocket I've reached 64 mph (70 on speedo) and I weigh about 240. You guys have lots of good info on the CG250 but things are more sparse on this board about the CB250. I've seen a performance camshaft online, but no specs are provided.

Doesn't look like an OHC engine in your photo.

I have been doing wheel work since I was a kid, about 30 years. I had no other choice but to repair my own wheels. There's no problems with ringing spokes and tightening them. It takes more than snugging up a few spokes to pull a rim out of true. There is more than one way to do things. If my way is wrong, then 90% of all spoke wheels are at risk of blowing up and killing everyone around. The dealerships and shops use the same technique as I to tighten a few loose spokes. Indepedent shops are where I learned how to repair wheels. These are China bikes. Most of them are not true from the factory. It was uncalled for the way you responded. We try to keep it civil around here.

12-06-2017, 09:51 PMI've not removed the rocker cover, but am thinking it might be possible that my engine is a 165 & 167 cobbled together? The 165fmm (CB250D-G) is listed as a camshaft upward but mine does not have the rocker cover to house the camshaft & chain. So, I bet you are correct. My bottom end is stamped 165FMM.
Here is the link for the 165FMM: http://www.zse.cc/productsdetail.asp...=368&CateID=43
Here is the link for the 167FMM: http://www.zse.cc/productsdetail.asp...=400&CateID=46
