As an addendum, I agree with Tim and hope your muse comes back to allow you to finish "Motorcycle"; there's so much fun yet to be had there, especially since Harry has non-magical resources the Order (or whatever Dumbledore's minions, carrying on his plan, are called) have no idea of, let alone what magical and related resources Harry actually has. Personally, though, if I was Harry in that situation, I'd be tempted to say "Your mess, your clean-up!"
