Thinking of turning my 99 Busa into a track bike...

The X1 is a track busa but that level of mod is gonna cost money. In your situation i'd let the rego lapse, remove lights, mirrors, airhorns etc and ride trackdays. Riders like Spencer and Gardiner got real good by learning to ride on clapped out chookies. The key is not being a poser with the most expensive track bike, but having fun with what you got. This way you can always get it registered as the youngins get older and are left on remote control.
