Started fiddling with my dirt bike today, too. Had to move it out of the back corner of the company shop to my garage, next to the 'Busa. Haven't even really looked at it for a couple of years - too busy. But now I have more time. No water pump issues here - it's strictly old school - 1983 Husqvarna WR430. Air cooled 2 stroke long travel desert bike. Needs new chain and sprockets and a rebuilt/replacement CDI. CDI is going to hurt; nothing on the old Huskys is cheap.
