Welcome to the forum....few things you might like to know...seeing as 32 people read this and nobody responded....I'll break it to you.
-The Vgas was a spectacular waste of money. It has been repeatedly proven they do not make any more power than a good setup with stock carbs, for stock engine size. You would have been far better off with Morley's carb kit, at a small fraction of the cost. Jon thinks these are the greatest things ever, and tuned properly can perform well, but so can stock carbs. I have yet to hear of anyone getting his claimed 140+hp, or even close to that. Jon has been known to well....ahem.....bullshit people. And for $2000....sheesh.
They have various unpleasant side effects, like they make your legs smell like gas and have been known to get finicky on hot engines.
-UFO has notoriously bad customer service, especially when it comes to items that are not ready to be shipped immediately. Excuses, delays, ect. Some people have had no issues with him, a lot of people have. Once he's got your money, you are strictly on the "back burner" so to speak. It's been around 2 weeks, has anything arrived yet? Has he contacted you with status updates?
-Japanese bikes had a speed limiter device inside the speedometer. It's fairly simple to disconnect. Japan-spec bikes also did not have v-boost(only US/Canada bikes got this, Euro/Japan did not). So right out of the gate your engine is down around 20-25hp over one with v-boost. Since you have vgas carbs this is kind of a non issue though.
I hate to be such a pessimist right out of the gate but it looks like you should have done a little more homework before diving in and spending loads of money. A Marks or Kerker exhaust, and a Morley carb kit will give you the most power possible without cracking open the engine. PCW(a reputable shop specializing in the Max in New York), has had mixed success with UFO's full systems, they've reported they can be tough to dial in across the rev range and don't produce the power of other systems (despite Jon's propaganda that his are the best and everyone else copied him). They had a bike with his full system on it on the dyno and were only getting around 120 for power. They say usually a full system and good carb tune will get in the 124-128 range. While they are an unbiased shop and don't want to badmouth any one thing, they have said they have had "limited success" with Vgas systems, most of the time they come in is when the owner can't get the bike to run right with them.
Anyway welcome aboard, I have heard that the Max is quite rare is Australia so good for you for getting one.
