XT660R wont run

I used the bike 60km this morning no problems at all, at 9PM a new front light arrived for my bike, i decided to change it right away, now it wont start.^

Bike is running:
KN filter
DNA stage 2
Delkevic exhaust
Power commander V
Dynojet autotune

You can get the bike running but in that case you will need to have about 50% throttle and it will only rev aprox. 4k rev and splutter.

I did manage to get one AFR reading on 4k rev and it seemed to be at 10..

Here is a video of it "starting".

Ive tried to reset to the yamaha original map, still wont work.

Seems like the power commander has died, when i disconnect the PCV the bike starts and runs fine. Talked to OTR and they told me to send the pcv to so that they can check the unit.

That's very interesting.

I don't think I've ever heard of a Power Commander going bad before; the connectors/connections and their optimizer, but never the PC itself. Make sure you report back with what went wrong with it...

I'm mighty suspicious that you fight a new light then the bike fails to start?
