Awesome, you will have a blast out there. Be ready to welcome a new addiction!!!
Coolant flushed..... you will flush out your coolant with distilled water. In case of a crash, coolant is very hard to clean up out there. Some places allow things like water wetter, you will want to check with your local tracks/organizations.
safety wired..... there will be certains areas of the bike where the exposed nuts will have to have a hole drilled and wired to keep them from un-screwing. Amazing things happen at races and track days that normally wouldn't happen in the street. If you have the right tools/bits, it's not hard to do. You will need to check with your local tracks/organizations if they even require it for open track days.
Ask ANY question, there are plenty of folks around with varying opinions that are good.
