Yzf r125 cuts out while riding and yellow light flashes

Jag_s · Jul 16, 2021

hi, my bike has been cutting out while riding and the yellow will flash fast continuously till I come to a stand still unless I hold the clutch in for a few seconds and i can bump it and ride for about 2-3 minutes and it’ll happen again.

I’ve recently given the bike a new oil, filters, spark plug battery and a new ignition coil.

Can anyone point me in the right direction as I don’t know what to check.

It sounds like from what the manual says is a dirty injector, run some seafoam in the fuel

Have you got a link for the right stuff and I’ll give it a try. Thank you.

I used a injector cleaner (redex) and the bike ran for longer today than before using but is still cutting out. Also, the error code 46 is started to show now. So I’m going to change the rectifier and see if that fixes the problem.

If not, am I correct that I would have to change the alternator ?
