Took the engine out of my 2011 450r for some maintance. After putting the engine back in, it was hard to start. When it did start up, the light flashes 8 times, meaning TPS. I did not take the throttle body off the bike. I did not take the TPS off of the trottle body either. And I did not unplug the blue connecter to the TPS. How could it have gone bad? What did I do to make this happen?
