The clutch switch is located under the clutch lever on the left handlebar.
When the clutch lever is pulled in this switch overrides the neutral switch to allow the starter to work even when the transmission is in gear.
This is handy when your stopped at an intersection and your engine dies.
As the 18 wheeler is bearing down on you, you can pull in the clutch, hit the starter button, release the clutch and be out of harms way as the truck roars over your previous location.
The sidestand switch is located under the sidestand.
Although it's a nice safety device that keeps you from riding off with the sidestand still down they have been known to cause misfires and engine shut offs.
It can be disconnected by undoing the electrical connector just behind the rear of the engine on the left side. It's on a harness lead that runs up the rear downtube to the main harness.
By disconnecting this sidestand switch the bikes wiring will always think your sidestand is up, so it will run normally.
This can get you into trouble if you forget to raise the sidestand and ride over a bump though. People have been thrown on their head when their sidestand suddenly bumped into an object and the bike highsided.
