its pretty easy, you buy and they ship, once arrive this end you will get a notification, by mail if i remember rightly, you then fill out the paper work as a personal import, pay the duty on it (i think i had to pay on-line) and send back all the paper work, box of parts arriives few days later, customs shiela was more than helpful, she also rang me back to say thanks for not being the usual dick-head on the phone about them taking money off us! It was about 2 years ago for me, was a cylinder head and some carbs, new carb, secondhand but ported head with new valves etc , cost me about $300 on top of the parts and shipping, i think the tax calculation is on the total price including shipping though, still pretty easey and not too expensive.
How's that?
