2005 Honda CBR 125 R - Answered Questions & Fixed issues

Sounds like you have a ground fault. I once had a car with a faulty ground wire on the headlight, when I put high beam on the speedo would jump to 170km/h and the indicators would glow dimly. Sure sounds like a similar ground fault to me, check all the ground straps, from the headlight or anywhere else you can think of.

Did you ever get to the bottom of this? My son has the same problem

the fluid in the carburator not set right

check for broken wire to your throttle ,or carb but try throttle cleaner first.

SOMEWHERE will be a little "bullet connector" for each wire, Ari. It may be inside the indicator housing or it may be inside the bike. You'll need to find it & unplug it, then keep track of it so you can plug the new one into it. If you can't find that connector, you won't be able to connect the new indicators...

hi mate it could be themostack broke. when it gets jamed it will not function tidy. it spouse to open and shut to stop the engine over heating..

check the spark plug. if was working fine before i would start there and work your way back from that. clean the spark plug and test on a meter top part to the tip on the electrode. then check the lead then the wire/s into the coil pack

Congratulations! Good luck with that. However, this is a place to ask questions. If you have a question about rebuilding the front end on your cbr, you could post it here.

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!

I have just had a similar problem but my bikes a 2006 model,approaching trafic lights it would just cut out and sometimes trying to riding on a straight road.The AA will say its the battery,dont believe him Its the spark plug,get a hot spark plug,my bike performs better now.

I had the same problem with my 636. It turned out to be just a cable problem. Try to see if all the electric cables work correctly and connected.

Good Luck,
Elad.

You may need to adjust you clutch cable or 2nd gear may be going out all togather.sounds like its not engaging all the way

Remove the back seat,then remove the screw that holds the front seat.With a philips screwdriver remove the screws fo the battery(FIRST the red wire-positive).Replace the battery,then reverse these instructions.That's all!!

take your breather cover off and see if that affects it if you went to a larger jet size you may not be getting enough air to comply with the extra fuel you're dumping in i would suggest drilling a few holes in the breather lid if it straightens up when you remove the lid. i ran into the same problem when i rejetted an artic cat 400

hiya mate dunno if you're still gonna read this, however - on cbr125s they commonly develop a rattle around the screen and front fairings (plastics).

dont book into garage - you will part with an unneccessary amount of cash - try undoing the screws/bolts of your screen first, then put them all back super tight.you can also buy rubber washers to put under the screws/bolts to minimise vibration.
if this doesnt work, do the same with all fairings around the front of the bike - take off and put back really tight. it is most likely the bodywork, i've had exactly the same problem when i bought mine and over about 7,000 rpm it does your head in!!! turned out to be some of the bolts not tight enough around the front screen.

as for the clocks im not sure mate, i'd advise getting a hayne's manual! sounds to me like fuse though if some things are still working.

The cost will be around $70. Any brand will do providing it has the same dimensions, voltage and amp rati

Those are the normal symptoms of a worn clutch. It will pull quite well in lower gears but slips in the higher gears. I doubt if releasing the clutch adjustment is going to give you a bit of grace, you will soon have to replace the clutch, especially considering the noise.

Your choke or cold start needs adjusting slightly.

There is no oil filter on the CR125R. The " filtering " is an oil change. Change the gearbox oil as needed, generally four times a year.

You cant !!
