I have an 04 ZX6R, and for some reason it won't start when it's in gear. I'm guessing this isn't normal, anything I should take a look at? When I have it in gear, it acts as if I have the kill switch on or something. I hit the engine start and no crank or anything. In neutral it starts up just fine.

 

clutch switch is bad. jump it together to make sure it is, and if the bike starts in gear (hold ckutch anyway, so you don't take off thru a wall) then just replace it.
also, just for fun, inspect your kickstand switch.

 

yeah, what he said

 

mine starts up fine in gear with the clutch pulled in

 

Mine wont start in gear either. I have an 05 model. Doesnt seem to be a problem. I guess it is just a safety thing.

 

MIne has been doing the same thing for a year or more now. It is a bad switch like they said, I just haven't gotten around to replacing it.

 

A sidestand switch will also prevent your bike from starting in gear.
