If riding again the next day, I just blast off the major crud on the rims, tyres, under the guards and under the engine. So the bike weighs a kilo or ten lighter the next day.
If storing for a week or more then much the same for me as the other posters. But I take my airfilter off. Actually intkae snorkle pipe and airfilter off, which also means seat and side plates off. Then I cover the carb intake with plastic using a rubber band to hold it on. I cork up the muffler. The get ready only takes me about 3 mins. Then pressure wash. Being careful to not blast water directly into: hand throttle, headstem bearings, wheel bearings, rear susp bearings/bushes, the top of the carb, or directly into/down the clutch cable. Then I quick hand sponge it using CT18 truck wash, then wash the suds off with the pressure washer.
Then I let it dry a bit, drain the carb float bowl quickly, then start it up and run it for a few mins. Then shutdown and I Inox oil a lot of things, incl spoke nipples, and all joints and bare metal, but avoid the brakes! The Inox oil coats the metal, displaces water, and next time you hit the dirt, the dirt/mud does not really stick so bad. So the next clean operation is pretty quick and easy. I have an RK o-ring chain and all I put on it is Inox basic oil spray before rides and after washing. No steady chain stretch or pain in the arse chain adjustment for me.
My pressure washer at home is a pretty weak little 1200 psi elec thing, but it does the job easy and doesn't use much water in the process.
