I love riding in the rain, its just exciting... a lot of people call that "white knuckle" but honestly if you look at it as a learning experience, it is really a great way to practice riding.
I say this because riding in the first place require that you pay lots of attention, it requires that you be smooth (regardless of road conditions you should be smooth). Poor weather riding will help you to learn a lot.
And especially if you are going out for a brief ride, don't get hung up on being dry... unless you have a great set of rain gear you are going to get wet... honestly its just water, come back in later and dry off.
Also- since you are on a SV (i assume since you are on SVR) - keep an eye out for larger puddles and wet areas, water gets into that first spark plug well and drowns the plug- if the bike starts running poorly this is probably the problem (It will be running on 1 cylinder...)
It will try and stall out but if you just keep the throttle cracked open a little bit she will take you home just fine on the rear cylinder.
What ever you do- don't panic, look and plan ahead, if you have to do something fast or in an emergency do it as smooth and calm as possible.
