Yamaha ybr 125 2016 wont start

[HarryC01]

been having a nightmare with this bike not even had it for 2 weeks and it has broken down on me and wont start back up. Had a recovery service come out and say my ignition coil isnt sparking as you can touch it as its trying to turn on and only shocks you once so i think that wire is faulty. My problem is i cant find the spark plug wire/ignition coil? not too sure what the correct name is as i have only just got my first bike and am very new to all of this would be much appreciated if anybody can help me. The lights flash on the dash when trying to turn the bike on and it just chugs away had to connect battery charger to it as it drains my battery fast trying to start it. Any ignition coil i find is not for the 2016 ybr only 2010 and older models but it looks the same connection as the one on my bike just not sure if that will work.

If the AA checked and said the coil is fecked, buy and fit a new coil.
Or used from ebay £20-ish.

But you probably need a battery too by what you describe.
And if the battery is fubar, it won't produce the voltage needed to make a big blue spark at the plug.

Coils rely on enough power in to provide enough power out.

Google Internal Combustion engine ignition system.

It is not rocket science.

Rocket science is a Tesla thing now.

PS what sort of 'mechanic' bases his diagnosis on touching an ignition coil?
Was it AA (vehicle rescue and recovery) or Alcoholics Anonymous?

Don't touch live ignition systems with body parts.

It doesn't take too much to interrupt pacemaker electric. Or it's advised not to fuckaboot and findoot.

Easiest and 'safest' it to use an HT current tester. It uses a neon bulb to show the 'power' of the spark current in the sparkplug lead.

Or ghetto, is remove the plug and hold it onto the engine metal as the engine is turned over. Watch for a big fat spark at the plug gap. (Having a spare plug to test helps too.)

Get your head into the books before lashing the cash.

It's only a big issue if you don't fully understand the theory of ignition.

Coils sometimes are not good or bad.

They suffer from weirdness too.

You 'should' get some indication of failure by measuring the insulation between the input terminal and the body/earth.
They should have substantial resistance. The OEM books should provide the specific values.

Do you own a multimeter? Do you know how to use a multimeter?
Sort of necessary for ignition diagnostics.

That's the wrong coil, that's for the early YBR's with CDI ignition
EFI YBR's use a 2 blade coil.

Fowlers have the correct coil in stock

IF you really need one that is !!

As per MCM, I'd do some more testing before spending

If the YBR eml gives you 33 (3 long 3 short flashes) that's it saying
it doesn't like the coil

pay attention and note the flashes
19 ( one long, nine short) is another common fault on YBRs

turn on the ignition watch the wee yellow lighty and count
it will keep flashing out the same codes over and over until you turn the
ignition off

NO!!
that's single blade CDI type coil
useless on an EFI YBR
did you not read wot i rote?

I dont reckon you need a coil anyway
code 19 is not the ecu saying its a coil fault, its related to the side stand switch loopback
and there's an easy work around for this

It's a pretty easy cheap and quick job to by pass the sidestand switch
in fact it will cost almost nothing to get you running again if you by pass it but more if you need and fit a new switch.

I have never owned a YBR but done loads of work on one for a local guy who sadly seem incapable of learning to do stuff for himself


As your a newbie some advice

TEST dont guess!
Buy a manual, read it and get to know your bike.
people who do this tend to have more reliable, cheaper to run bikes

Buy a multi meter, they're cheap and can save you plenty of time and money

Ask on this forum first!
There's a shit ton of pisstaking goes on, but most of the folk here
are pretty smart and experienced and I've never known any of the regulars to deliberately give bad technical advice.
so pay attention and don't flounce

Have to go out but in short:
the quick fix is to short the black and black/white wires at the igntion switch together to by pass the faulty side stand switch

Be careful not ride off with the side stand down and look into
getting a new switch or fixing the wiring fault

It's not sparking because the switch is telling the ecu not to spark. Thats why you need to bypass.the switch.

It's electrics. Did you do any science at school?

OMG
Only been here 10 minutes and Nobby's got right into him

Now, the question is, does he flounce or not?

In my defence I've had a torrid couple of weeks and am really not in the mood to be gentle.

WD has pretty much told you how to fix it based on the information you've given.

from here you have 2 choices;

1) read and learn (stop to google terms you dont understand etc) then maybe you can fix it yourself for free and also learn more about the machine your riding.

2) just pay someone to fix it, not only this time, but every time its got any slight problem.

one of those choices will make you poor, the other choice will make you self reliant depending on how far down that path you go.

stinkwheel Well I just had my hands up a pigs fanny. Which makes your concerns pale into insignificance.

[WD Forte]

Up to you
Do that and you'll be none the wiser, out of pocket and prey to any
half assed mechanic in the future.
Get it brought home and do it yourself and you'll learn

I'm told by my YBR owner who also has 2 delivery scoots
bike shops around here charge from 40 to 100 quid an hour
for labour.
There is a cheaper place he goes to but they're fucking useless
so he often has to bring it to me to put right after they 'fixed it'

It's an easy job, I could do it with a screwdriver, a pair of cutters or pliers and some electrical terminal block in less than half an hour.

Just had butchers at the YBR manual
Try this
Select neutral
turn on the ignition and pull the clutch lever in and hold it in as
you press the starter
If it starts but cuts out as you release the lever the side stand switch is
the fault

all this does is confirm the fault not fix it but at least it does tell you the
black/white wire fix will get it running so
all you need to do is cut it, strap it to ground and off you go
