[SV650] Greetings and questions

Usually, replacing the coolant with water for a track day and  
forgetting to prep it for winter. Or leaving it outside for a midwest  
winter. (I'm told they get cold...) Easy way to tell if it's a freeze  
plug, look in the radiator. If there's a bunch of scummy oil there  
it's a freeze plug. Otherwise your first guess is probably right.
