I'm travelling to the UK, and pass-by very close to the Krazy Horse EMPIRE HOUSE (the one at Lamdin Road - Bury St Edmunds - Suffolk). I guess they can sell me that kit, right?
That is the main Krazy Horse site and well worth a visit. They have 2 buildings, the Morgan's are in one and the Café in the other.
If you are interested in something specific such as the air filter it's probably worth letting them know beforehand so they can get on in stock for you.
Re the AR Stage 1 - when I had mine done a while ago the air filter alone didn't make much difference. It was the exhausts which really freed the engine up and let it breath properly.
