My brother owns 2015 Super Tenere and has had a recurring problem of the bike refusing to start when there are no good reasons why that should be so .
Twice it happened and the bile was hauled to the dealer where it was got going again the first time but they did not explain ( or know ) what was wrong other than suggesting the battery was getting old and they replaced it . Bunk the first battery had enough juice , but okay , almost two years old .
Second time was later with the new battery . Many attempts to start it , recharged the battery, ,used boost cycle on charger while cranking .No go . Hauled to dealer , and itstarted when they cranked it with the starter .
The other day he started the bike and moved it out of the shed and shut it before getting suited up for a ride a half hour later. THEN it refused to start . Many attempts and two days later it still refuses .

Seeking info on the internet I find some advice , but nothing that was of much help .
- It was suggested by one source that shutting the bike off after a very short time does not bring engine temperature up to a level needed for the bikes computer memory to be able to figure out what is needed.
When cranking over the engine it makes some sounds as if it might be willing to start, the right side exhaust pipe does warm up , not the left side, it will simply not " catch " and start up.

It looks like this is a known , not a rare ,problem .
If A bike is in good tune and operating normally , and starts normally , what is the excuse for such a problem ?
I suspect it has something to do with the fuel injection computer brain being
somehow scrambled in its thinking , It seems to be not sending a spark signal or adding fuel for some reason.
Could they reprogram its chip/
Any advice ??

1 nothing wrong with fuel , it was filled the day before with good new clean
gasoline ; the bike started normally 30 minutes earlier
2 we did the disconnect- battery routine , did not work
3 The battery terminals are shiny and clean , as would be expected after only
one year
4 Not a single add on- accesory to sap current. Battery is strong and was recharged after all the cranking of the engine . Even with the added power of start-assist from said charger it still refused to start .

with fuel injection i only have experience with cars, and these usually have the OBD2 so you can easily plug into ECU and see error codes.
I would download the workshop manual and enter the diagnostic mode that lets you read error codes. you dont need any specific reader for that

Then go item by item and check if everything is to spec

I'd suspect there is a sensor that either is out of spec or send the wrong signal in certain conditions . have you ever taken one or both sparkplugs out and see if they're sparking or if they're wet or dry ? That will give some idea as to which side of the problem to look at - spark or fuel . Do you here the fuel pump building pressure ?

maybe twist the throttle backwards while attempting to start , trying to close the throttle harder and then see if it starts . There can be sensors reading the throttle is open if cables are tight thus the ecu won't send a spark , however , if your one pipe seems to be getting warm it many suggest there is spark, just not fuel or too much and it's flooded badly (the reason I want to know if plugs are wet or dry ).

One other thing to try , turn key on , twist throttle to half while cranking, pause then go wide open all the while cranking, doing all this in a span of 4 seconds . This would be an attempt to clear unburnt fuel . If the bike is getting flooded , i'd swap the plugs to the Iradiums . I have them in just about everything nowadays , not for any perceived performance gain but soley because they will not foul and will spark covered in oil or fuel where std plugs short out at any little covering .

Faulty 02 sensors are a cause of problems on all FI engines, try THIS.

Mezo.

luckily dont have even one injected bike, but in cars it's definetely true
my subaru forester started running like crap and an "check engine" light appeared. One quick scan with the OBD2 reader and it was indeeed the O2 sensor

just seen the manual and the Super1200 has a built in diagnostic mode you can access

had this a few times on my S10 and it is a known common fault. Basically, as I understand it, everytime you turn on the ignition the injectors pump in a small amount of fuel as the fuel pump primes (the whirring as it powers up). This floods the engine in effect and to avoid it you should turn off the bike using the kill switch and when turning it back on leave the kill switch in the kill position until the clocks etc have cycled through the start procedure. It has worked for me and I haven't had a problem since following this procedure.
