Turn it into a race bike! Seriously, if you have one that is collecting dirt you should turn it into a race bike. Clubsport lites/Formula 4 racing is cheap enough that you don't need to worry about sponsors, wives or mortgages. Get out there and push that old bike to its limits in a place where there are no cops, and a dozen other people fighting for bragging rights at pub later.
