d.j.jake1/2,
Welcome to The China bike forum. What exact help do you need? There is lot of knowledge of the CG125 clones here so ask specific questions.
I have the CG250 in my Dong Fang bobber and the engine has been solid but not too powerful.

[d.j.jake1/2]

actually sir i want to know if anybody have a manual/ i mean users guide of this bike. or any the same users guide of this kind of bike.. i just need it to do some trouble shooting. like ive been to several mechanics but they fixed then sometime problems goes back. specially on my rear brake. its noisy klinging. really embarrassing.

What kind of noise is the rear brake making and when does it occur?

Just in case you are not aware, I googled and found the forums below.

So you have a rear disk brake that is squealing when you are just riding along or does it do it just when you are braking?

[d.j.jake1/2]

yes sir its squealing everytime whem im not braking. then if i brake it stops and sometimes the brake pads just stocked up. and doesnt return to its proper clearance. the pads just bite the disc and dont let go. so the problem is the bike cant run and the brake clamp is heating too hot. i think the master brake pump right over beside the right drivers foot peg has problem. any idea how to service it? like opening it?

Usually if one piston is stuck, then the caliper piston is hanging. If both are stuck, the master cylinder is not releasing pressure.

Have you tried to open the bleed fitting on the rear caliper to release the pads? If that will allow the pad to retract then there is a problem in the master cylinder not releasing the pressure. Be sure that some debris hasn't gotten down into the small bleed port in the floor of the master cylinder reservoir. Also, highly unlikely but make sure that the reservoir is not overfilled when cold.

If opening the bleed fitting does not release the pads, then the cylinders are sticking.
The caliper mount bolts go through sleeves that need to be lightly greased to all a little movement when the caliper is activated and released. Be sure that the caliper isn't hanging on the sleeves.
