I hope I can explain this correctly:

When I try to start my bike up, it fires up and will only stay on if you give it some gas. As soon as you take your hand off the throttle the bike dies. The front cylinder spark plug keeps getting fouled. It almost feels like the front cylinder is not working. I dropped the bike off at the dealership because I am at a loss and have no idea what is going on. Anyone have any ideas?

When I dropped it off the tech said something about the TPS, which I really doubt. He also mentioned something about the engine temp sensor, I doubt that also.

I hope I explained that okay.

The TPS was my first thought, but I am not an XB expert. Did you put in a new ECM?

I forgot to hook up my temp sensor once after playing around with stuff under the hood... It ran very poorly. I'm thinking that because there was no head temp voltage being reported to the ECM, that it defaulted to delivering fuel/spark like it was warmed up. I don't know if this is your issue, but it certainly made a big difference in the way my bike ran...

The plug wire was cool, everything looked alright, me and a friend of mine worked on it for a while. It got to the point where we were both out of ideas, so I hauled it over to the dealership. I hope they don't drop my bike again
