1thump: The easiest thing is to just disconnect the switch from the harness: find the switch on the side stand and follow the wire up to the first connector you get to, and unplug it. Secure the separated connectors accordingly, and don't forget to put your side stand up, since you now have no reminder. You can remove the switch altogether, but you'll still have the harness-side connector to tape over and secure.
There was/is a problem with the side stand cutout switch mounting on the Bullet models which caused it to intermittently and temporarily kill the engine while riding - sometimes just causing a hiccup, sometimes stranding a rider. Many (dare I say most?) owners disconnected the switch to prevent the problem. It was discovered that by enlarging the switch's screw mounting holes a little bit, the switch could be better positioned so as to prevent the false cut-outs. I don't know if this problem has carried over to the GT models.
But it doesn't sound like you're having that problem, you just want the switch's function gone. Somewhere here recently, I think somebody came up with a wiring mod that only killed the engine when the side stand was down and if it was put into gear, so you could warm up the bike on the side stand in neutral, but still have the safety feature of engine cut-out if you popped it into gear with the side stand down.
SpaceAviator: as far as I know, all the UCE Bullet and GT models are shipped with this "safety feature".
