So, I went to go for a ride on Saturday and my check engine light is on. Seemingly, for no reason. Last ride, no light. Saturday: light. Hmmmmm. No effect on performance, though I did not womp on it with the light on. I did wash the bike and adjust the chain since my last ride, but I doubt that caused the light.
I called the dealer, mine is outside the VIN range for the recall on check engine lights.
I have done the following mods: Delkevic Cat-Delete and carbon can Givi sport screen
SW Motech frame sliders
SW Motech quick release mini bag
Adventure Sport Mirror extenders
Yamaha Comfort seat
Evotech Radiator and oil cooler guards
3M clear paint protection
Vagabond fender eliminator
Pazzo Levers
Speedo Angel gauge screen protector
Slip Screen Head Light protectors
Removed passenger pegs
Removed peg feelers, tired of dragging them.
The only thing I can think of is the Delkevic decat and can, but I put that on over 1300 miles ago and no check engine light. Now, all of a sudden, I get the light.
I am taking it to the dealer tomorrow after work, which is a PITA because they are not close to my house at all. I live between Paso Robles and King City on the central coast, no dealers even close...
Anyone got any ideas what the issue might be?

What was the last thing you did to the bike mechanically? Even as simple as chain cleaning on the rear stand. I would double check alignment on all of the sensors like the front and rear wheel sensors. Not the first time I've heard of misalignments being the source of check engine light. Also, I was checking to see if there's a diagnostic mode on these bikes, apparently not??? So found this recommendation from MT10 forum about how to self diagnose your codes. The cost might be steep, but I've found having an OBD reader is invaluable. mt10forum.com/threads/677-How-To-Clear-Your-Own-ECU-Fault-Codes |

Did you start the bike when it was on a stand? If the rear wheel turned, there could have been an TCS light and I think it will also throw a CEL.
Also, what RedAndBlack said above about the code reader. Have you gotten a reflash? If so, you may have to get an update to check the codes.
Cheers,

When I bought mine about 2 months ago they were telling me about some Reflash with the side stand switch that could throw the CEL. Something about turning on the ignition switch slowly can do it, I wonder if you disconnect the battery you could clear it?

Something about turning on the ignition switch slowly can do it, I wonder if you disconnect the battery you could clear it? There is a service campaign notice that came out in Nov 2016. There are two switches in the key lock, the first turns on all the electronics, the second engages the whole sidestand/neutral lockout system. The newer electronics energize in milliseconds compared to the older systems. If the key is turned too slowly the ECU system doesn't see the interlock system engaged and it throws a code. Disconnecting the battery will NOT clear it, you have to use the diagnostic tool. Dealers know about this and they usually do the reflash when the bike is brought in for any other reason. It takes about 15 minutes, no charge, of course. I suspect this is what is causing the OP's light. |

I did a chain adjustment on a read stand. I did start the bike on the rear stand.
No reflash on the ECU.
According to the dealer, over the phone, my bike is outside the VIN range for the side stand recall/reflash.
I am headed to the dealer after work today, so I will hopefully know soon enough WTF is going on.
I don't recall turning the ignition switch slowly, but I cannot be 100% sure that at some point I did not turn it slowly. Kind of a PITA if that turns out to be the issue. Is there a reflash that will correct that code from appearing again?

Is there a reflash that will correct that code from appearing again? The reflash of the ECU changes the logic so that issue won't occur again. As I understand it it won't change or reset any other changes you have made to the ECU (custom tune, etc), it just addresses the false positive regarding the side stand circuit.
If your bike is out of the VIN range it might just be a random code, see what the dealer says about what code was thrown, then go from there.

Dealer says it is the Exhaust Valve code.
Interesting the bike went 1300 miles before tripping the code. Ordered the AUTEL AL519, 4 pin Adapter and a servo buddy. All bases covered....

I had a similar experience last month. I had owned the bike for 48 hours and put 70 miles on it when the engine light came on. Bike ran great. I wasn’t happy though, obviously. First thing that ran through my mind was that someone made a mistake during assembly.
Dealer said the exup valve was stuck open. They freed it, lubed the cable and it’s been fine since (1000 miles since then).

So, upon looking at the service record, there were actually three codes:
EXUP valve
Servo
and Speed Sensor
Note to all, don't run your bike on a rear stand!!! I figure what happened was, I ran it on the rear stand to lube the chain after adjusting, speed sensor code pops up. Get to the café to meet my friends Saturday morning, pull the seat, pull servo cable, started the bike, now I get the servo and EXUP codes. Can't be sure I did that, but All's well that ends well. At least this prompted me to buy the ODB reader and adapter cable so I can read my own codes moving forward.

I'm thinking that you must have had the bike running in gear on the stand, because I've started mine many times on a rear stand and have never had CEL come on. Please be careful messing with the chain with the bike running. At our local track club we had a guy lose a finger while cleaning and lubing the chain on the rear stand with the bike running.

I've run the bike in gear on the rear stand and got no CEL, I never thought about it. But I won't do it again.
No need to have the bike running to clean and lube the chain, that is always a dodgy and potentially unsafe way to do it. Actually easier to just put it on the paddock stand and do it all manually.
