I've done this many times....it's known as "the drill" what I do is close to what everybody else does here. I'll turn off gas, pull the plug,remove air filter and dry out filter as good as possible, drain the carb float bowl, stand bike on end and let the exhaust drain, flip bike the rest of the way upside down, and in high gear, spin rear wheel for aproximately 60 seconds to let the water get thourly pumped out of the cylinder, re install plug and air filter, turn on gas and choke, and it will then start. And by the way, I wont let it wreck the ride, I'll continue as normal, and finish my maintenance at home. when I change the oil I dont do anything special. never had any problems after maybe performing the drill a couple dozen times.
