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.

:eusa_think: 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...
