SOURCE: cbr 125 choke problem

It sounds like the choke line may not have been routed correctly when the new one was installed. Remove the gas tank and check to see that the line is not being stretched anywhere along the way AND that the gas tank when re-installed is not stretching the line. The line may have been kinked when installed. Look at the mechanical movement of the choke at the carb. Does it operate freely? Remove the air filter and look inside the center of the carb, (you may need to use a small mirror for this), does it look like the choke is opening and closing properly when the choke is moved on and off?

SOURCE: honda cbr 125. my friend changed the air filter

Hi, i replaced my air filter on my cbr but it wouldn't start for me then i realised that 1 of my fuel lines were not connected properly when i put the fuel tank back on.

After that it was fine, check and make sure that your fuel lines are connected correctly under the fuel tank because they are a tight fit and therefore they can slip off easily if not connected right, you should see that there are 2 thin pipes that connect under the tank and then see if they are connected to the rest of the engine ok, but i'm not sure why it would be overheating on you!

SOURCE: My honda cbr 125 feels is hard to steer as slow speeds.

Sounds like the cap nut in the center top of the steering stem may have been tightened up a little too much. Get the front end into the air and turn left and right. Stiff? Loosen the cap nut until the handlebars move freely. Now it could also be that the steering stem bearings need a bit of grease. Some dis-assembly is needed for that fix. The only other thing that would make the steering stiff is low tire pressure.

SOURCE: what oil do i put in my honda cbr 125?

I believe the manual calls for 10w40 GN4 Honda oil. Any 10w40 motorcycle oil should be okay. I run Shell Rotella T 5w40 synthetic in both of my bikes and it seems to work very well. Stay away from the car oils with the "energy conserving" labels as the can cause the clutch to slip.

Hope this helps.
