2008 YBR 125 not starting

[tom_m]

Just popped round to have a look at brothers ybr, it is a 2008 EFI model. when you try to start it the engine management light (orange)flashes repeatedly, does have a spark but just wont fire up, tried different plug, tried to bump it and kick it over without any luck.

anybody any ideas?

have you tried putting abit of petrol down in the sparkplug hole mate might give it abit of luck and I allways though that the light comes on normally when the bike isn't ticking over

The way the light flashes will be a fault code

How many times does it flash and in what timing?
Ie. pulsing slowly/quickly

I had that once..think it was just a knackered/low battery
When it's too low the injectors can't work, FI madness

They whirr up loudly for a few seconds when you switch the ignition on (before starting the bike) and stop, if you've got a multimeter i'd test the battery voltage, YBRs hate having low power I swapped out for a motobatt was sweet as a nut then

if you've got two ybr's swap batteries and see what happens
I doubt it's fuelling tbh as the ECU does it all, if it is it's bad though

When you try to kick it does the same, the light pulses constantly. The 2012 doesnt have a kickstart , but it does have a big black grommet where the kickstart is on the 2008 one so im assuming one could be fitted (yam cutting costs ey ?).

I never tried using the rest of the electrics, as these stoopid ybr's dont have a headlight switch and full lights will only come on once the engine is started. Im gunna go round in morning and have a proper look, swap batteries over and check electrics etc.
Id ask my bro to help me but after the comment he gave me the other day i dont thinkso.
"I thought you switched it to high beam when it was night time so you could see easier, wondered why people have been flashing me for the last 6 months" .... what a bellend

just for reference that bike will start without a battery if you kick hard/rapidly enough, though it's probably not too healthy, the rev counter goes nuts and the light barely works

though according to my haynes manual that's a ecu fault code, and is stored until the memory is cleared, the faults that won't let it restart are:
19-no signal from black/white wire between ignition and ecu
30-tip over sensor(triggered)
33-ignition coil
39-fuel injector
41-tip over(bad wiring/faulty sensor)
50-ecu malfunction

the light flashing pattern says which code it is, first number is long flashes, second is short

15 = 1 long flash, 5 short flashes

When i was at my local dealer a few months back someone had the same problem. I was paying attention fully but i remember them saying it means the bike isnt priming the fuel correctly or something.

I might be wrong.

was thinking it might be that, a loose wire is probabaly more likely than all the others

It won't start sometimes, the warning light flashes at me. It sort of starts up for a second then cuts itself out. Bloody annoying when you want to set off and you have to fiddle around with everything to get it going..

I have also been getting this problem for the last few weeks. The bike eventually gets started by turning the ignition off, and then back on, usually within half a dozen times the engine will keep in. I just had the Haynes Manual delivered today, and this afternoon have taken the left cover off to check the battery and the fuse and the electrics in there which all seem to be ok, so next at the weekend, I will check the wiring at the ignition, and then follow it down to the ECU (although I'm not looking forward to taking the tank off!)

Have you guys had any luck sorting it out??

It's part of the ignition black to black white, if you go into your headlight you will see it going into a red block which is your electric start, make sure all the wires are secure, my electric start came loose once and was being weird, somehow

I have taken the headlight off, found the black and black/white and quickly inspected the wires, couldn't see anything immediately at fault, will try again at the weekemd when I've more time. Did think that I'd cracked it when I found the dummy red wire in the connector, but that turned out to be the way it should be.

I know this is an old thread but no resolution ever seemed to be found, so this may be worth saying. I recently had this issue (error code 19 on start) I know that some have replaced their barrels to no avail but before trying anything else try this.

Wiggle the key in the barrel to see if it starts (or push down when trying to start) if this seems to be the issue:

Try squirting some switch cleaner directly into the igniton barrel (use the little pipe or your key to prop the plastic bit open) and give it plenty. Leave it 5 minutes and hey presto, worked for me.

Could be condensation (as it happens in winter) collecting in the barrel or just dust.

Hi everybody,

I get the same blinking pattern with my 2010 YBR 125. Trouble code 19. One day the bike would start, and the next not. Sometimes it started again just by insisting a bit.

Switch cleaner spray directly in the ignition barrel worked like a charm for me.

Thanks for your advice.
