So I picked up a 2010 dragon 800 with a new engine in it and when I was going through it I found a empty conector by the ecu. So I looked at my brothers 09 and it is plugged into his knock sensor. So I looked closer and there isn't even a sensor on the engine. I have road it a couple times with no issues, no check engine light and bogging or lack of power.

Dose any one know if there was a aftermarket mod or re flash that rendered it useless. As far as I can tell it's only a engine with a fix kit and slp pipe. Any help would be useful.

Sent from my S5 while I am slacking at work.
