Re: CB125F 2017 tickover issues
Again I know this was the cbf125 so not the same model, but I had to change my ecu as it was leaning the mixture too much when warm. Secondhand ones can be picked up for near £20... maybe worth a try?

Re: CB125F 2017 tickover issues
The saga continues, replacement oil sensor and lambda probe made no change, however I did a test with it running with the spare oil sensor connected but not in the engine so it was seeing cold oil all the time and it sits fine st about 200rpm, switch it over to the oil sensor in the engine that's hot and it immediately dies, turn it off and back on still dies, connect it back up to the cold one and its fine again, so my assumption now is having changed everything else that it must be the ecu.
Anyone know if the ecu on this would be linked to the ignition coding wise? Or can I replace the cu without having to replace the ignition set?

Re: CB125F 2017 tickover issues
I'd just tuck the 'old' sensor out of the way on the bike somewhere with the wires attached.
Re: CB125F 2017 tickover issues
Tempted to do that but I'd like to resolve this plus it's being sold and I'd rather sell it honestly than bodge it, luckily the parts are cheap second hand

Re: CB125F 2017 tickover issues
No idea on the matching of the ECU to the bike, but I’ve not had that on any of my other 125s before....
Hope it works!

Re: CB125F 2017 tickover issues
It runs!!!
Replaced the ecu tonight and done a couple of cold starts and several hot starts and it sits and ticks over like a Swiss watch so anyone want to buy a fuel pump, throttle body, oil temp sensor and a lambda probe for a cb125f?
Thanks for the help and advice all

Re: CB125F 2017 tickover issues
Good news. Bizarre how these things go.
It’s one of the things I love about smaller bikes that you can replace a fair few parts for relatively little.
Enjoy!
