Ridin in the city, the bike warms up and usually stays above 210. Has anyone made a switch to manually turn on/off the fan, or leave it on all the time? Does the fan get power from the battery or from the alternator? I dont think it would drain the battery, but what do i know...

Lots of people do, and most the time all you have to do is slap one terminal of the switch on each side of the thermostat. Summer and/or city riding means they just keep the fan on. If your alternator + regulator are working, there should be no drain on the battery (depends on the system, but in general).
