If you have changed the exhaust/air filter/ or installed a power commander you have changed the way the motor breathes and will need to be compensated accordingly.
Check what gwoodman said as well.

SOURCE: how to start the gsxr 750 after running out off

It should start fine - unless you have drawn gunk from the bottom of the tank into the fuel line, in which case you will need to strip and clean the carbs.
