White smoke sounds odd... Blue smoke I can see as possible oil burning, but white smoke would be indicative on, say a car engine that a head gasket could be the problem.
As for the hole on the bottom of the exhaust, yes probably there to release the water byproduct and prevent rust of the exhaust...
I probably wouldn't plug the hole you have for just that reason. Have you checked the compression?

2005 GZ250 completely stock other than complete top end rebuild with new piston, rings, and gaskets. Entire new top end with all new valves and cam.
Got approx 50 miles into a ride yesterday and this white smoke like a ninja smoke screen started coming out of the tail pipe. The bikes starts and runs perfect.
No idea where to start troubleshooting.
