If the lights come on and the gauges sweep and the idle stepper motor operates it sounds like you may have a sensor problem. The kickstand, clutch and gear sensors will prevent a start. The delta morning to night is likely temperature (unless you garage stays the same temp all day). The change may be enough for the faulty unit to make ground. You can also check you crank angle sensor and clean it (3 minute job). You could also bypass the kickstand, clutch and gear sensors one at a time to see which one might be causing the problem. Just take the power lead to ground and that satisfies the interlock. Check out the service manual for details on wire coding.
