I would make sure all the plugs are on good, and all wires are not damaged. I am not sure if you can get to the sensor without tearing the motor down, that would suck.... Hope you get it figured out...

what part of SoCal are you in?

Also, your initial description is a little vague. Which side cover did you break? If you broke the side cover with the crankshaft pickup sensor, theres a few things that could have gone wrong when you replaced it. If you didn't transfer over the sensor correctly to the new one, it won't pick up the signal. It is possible (but difficult) to install that sensor backwards. Also, when you remove that cover, there is a 3 inch metal dowel that holds a cam chain guide in place, if that dowel comes out of the motor, you run a high chance of having your timing chain skip a tooth, meaning that all of your timing is off and when you try to start it, you could have bent the valves.

I only know about that, because I just replaced that cover and got a call from my suspension shop today saying my timing was off a tooth. I tried to be careful when I did it, but I guess it still jumped a tooth. I got lucky because no one had tried to start the bike yet, so I didn't bend/break anything.

I was just down in anaheim today getting my frame welded. Tore a nice little chunk out of it. If the new sensor doesn't work, just post back up in here or send a pm, i stalk the forums regularly
