I know many here will disagree but I've often taken mine to the car wash and used the high pressure soap and rinse on most of the bike. Takes off the bugs and goo and gets into the nooks and the spokes I often miss with a sponge. I avoid the fuze panel area and try not to spray up under the tank where most of the wiring is. My theory is threefold First, it's an English bike certainly they would not build a bike that can't get wet. Second, how is this different than riding in the rain and if it's going to die when wet shouldn't I know now? Lastly, it's a lot easier than spending hours detailing it with rags. Afterwards I just ride it to dry it off. 19,000+ miles and dozens of washes and never a problem yet.
