Just acquired her with 4k miles (USA) Not a lot of them in the US.  Had a Trike kit on it that I removed and sold, so back to completely stock.  I've been perusing the Forum a little so as to glean some info about them. 

I ride fairly modified 2013 Honda PCX150 that I work on myself so know a little bit of my way around a bike.

Was wondering if there are any glaring things that I should be addressing immediately with this bike.  It runs well, but a little rough til fully warmed up. Wallows a lot when cornering though which could be from stock old tyres, or maybe the fork needs service? Take off is a bit sluggish with a fair amount of vibration, but at 100kph/60mph it rides and runs butter smooth.

I welcome any advice from all of you with long term experience as I'd like to get and keep my new ride on the road for awhile to come.

Cheers!

There are a couple of things you need to be aware of with the 500 models, nothing serious though.
You must have the brown chipped master key and keep it safe. If anything goes wrong with the immobiliser, which is built into the ECU, you need it to reprogram any new decoders or keys you may add. Without this IF it goes wrong you will need a complete set of keys, locks, decoder and ECU all from a single scrapper, or brand new. Either way eye-wateringly expensive.
The clutch can be a bit juddery and sometimes squeals like a sealion - not a problem, more of a feature.
The steering head bearings don't last long but they are easy to change if a bit fiddly. These can make the handling and steering feel very odd, check for a slight notch feel in the straight ahead position, if so then change the lower bearing. A trike kit might make this worse as the steering is used more when the bike can't tilt.
Belts - only use the OEM Mitsuboshi ones, don't be tempted by 'performance' pattern parts, they are not as good, and don't do the mileage before snapping without notice. Also DrPullet sliders improve the initial launch by going 15% lighter than the stock 28g rollers if you have the 6 roller variator or 21g for an 8 roller set up.

I was going to attach a picture of the only key that it came with, but can't figure out how to insert it.

The master key is brown and chunky and has a little pivoting pocket for the immobiliser chip. The normal key is slimmer, black and has a blue Piaggio badge in the centre.
If you only have the black one then look after it and keep your fingers crossed the decoder never goes faulty.

UH oh.  All I have is the little black key withe blue badge. That's a bit worrisome, since I planned on using the X9 to get farther from home. Anyway to disable the immobilizer ?

I don't think anyone has found a way past the system used on the X9. It's a 2 part system, the actual immobilisation is part of the ECU, both fuel and spark are disabled. The key is read by an aerial around the ignition barrel that feeds into a decoder box which passes a digital signal to the ECU to disarm the immobiliser.
The ECU is locked for life into whatever master key chip is first used when the bike is new but the decoder simply stores up to 4 service key codes for daily use. You need the master key for the programming sequence to add service keys. You also need it to add any other new components other than the aerial. You could clone the key you have to gain extra ones to work around not having the master key.
I think there is one company that claims to be able to wipe the ECU of any stored codes so you can start again with it but it isn't cheap.

I found a dealer near me in Chicago that may be able to help me with the key situation a bit, so I'll keep my fingers crossed for that. 

I'm really trying to like the Scoot, but the handling is killing me.  The headset bearings feel fine, but it just feels like it wants to fall over when cornering. Could be the tires, but they are in good shape for the age, and the contact patch is comparable to my other scoot and moto.

Is their any adjustment to the handlebar at all? It's pretty low and I'm not that tall.

I put the Givi fairing on and at the lowest setting it's about 40-50mm taller than the stock and I can still see over it so that's good.

I have yet to crack open the cvt to see how many rollers are in there, was hoping I could figure that part out beforehand so I don't have to crack it twice. I want to install some Dr Pulley sliders.

Are you absolutely sure there is no notch in the steering dead ahead. Your description is spot on for either notched bearing or over tight pre-load. Stick it on the centre stand weight the rear and move the steering from side to side and feel for a slight tightness in the straight ahead position. The pre load should be just tight enough there is no play and the bars swing freely, in fact so freely the brake cables and wiring tend to swing them to the left where when the steering lock is on the bars spend most time. If they are tight the steering is very weird feeling as the bars can't move the very small movements you barely are aware of making when cornering. The notch gives a similar feeling as the bars don't move, then gives and you feel like the bike is tipping suddenly into the corner.
The first 2004 UK models had 6 rollers basically from the SL model but with 28g rather than 30g rollers, but by 2005 they had 8 rollers but when exactly the change was made we don't know. It is quite likely they standardised on 8 rollers by the time they exported to the USA.
I wouldn't worry about the key initially just never do anything electrically silly like cross polarity or shorting out things. The decoder and ECU are extremely sensitive to this. Always disconnect the ground before doing any wiring mods.

The center stand is gone, removed so the trike kit could be installed.  I found one on EBAY for a 2007 just trying to verify if it will fit.
I'm bicycle shop owner/mechanic, so I'm familiar with Headsets, but not so much on something this heavy. I have a small cycle lift that I can get it off the ground with so I'll give it a better exam with that.

You could retro-fit the hydraulic stand as I doubt Piaggio cut anything from the loom, I bet the wiring for the controller and button are still there behind the plastics. They are a doddle to put on the stand manually though.
The stand bolts to the flat plates on the lowest point of the frame below the sump. It fits up between them and bolts with 4 10mm bolts 2 either side. A completely self contained sub assembly. Not sure if the US version has a cross bar bolted in it's place as I suspect it's a structural part of the frame for cross bracing. 2004 to 2007/8 were all the same, previous ones lacked the foot lever and only operated hydraulically. They all interchange.
The X9 is very sensitive to tyre wear so if it's been a trike the front tyre may look OK but could be 'cupped' just enough to make it feel odd.

 I ordered the manual one on ebay, It's the entire assembly from a wrecked 07, including all the mounting hardware for $41 US.  Not bad.  Will be here friday so I'll be able to get a better feel for the Head set.

If you've rotated a worn rear bicycle tyre to the front, Its that same feeling, like at a certain lean angle, your riding on an extremely narrow edge/contact patch, and feel as if lean just a little further, the bike is going straight to the ground.

Thanks you for all this help and advice!

Only to align them so they are centred, they have no tilt or swivel, they are a welded assembly as they simply clamp to the top stem. Tighten them enough they don't move but no so tight a thief trying to break the steering lock simply turns them on the stem. If they were adjustable the covers wouldn't fit and you can't really leave them off, too much exposed and not waterproof connectors under these.
Unlike the Japs, Italian bikes of this type don't have waterproof connectors but rely on them simply being tucked up inside the plastics hence a good squeeze of a silicone inert grease inside each one is a good idea.

The workshop manual is on the site in the help section for the 500 Evo if you haven't already found it.

Finally got around to servicing the headset, all it need was a little Triflow squirt to each bearing to liquify the congealed grease.  Mechanic in Chicago suggested it and it worked.  Battery is completely dead so will test ride it when new one shows up.

Got her back out on the road again and runs like a top. Last 2 things to do are the Rollers/Sliders and belt in the trans.  Is there any way to tell if its a 6 or 8 roller setup, or do I just have to crack it open?

There isn't a reliable date by which 6 went to 8. 2004 is definitely a 6, 2007 most likely an 8 in between could be either. Date of first reg isn't enough as some bikes sold to order others sat in stock for ages. Belts are simpler, all 500 Evo used the same Mitsoboshi OEM part 832738.

I changed mine from 6 to 8 and fitted Sliders, on a second X9 I used to have I stayed with the 6 and fitted sliders to that too and I preferred the 6 roller feel, both with a similar percentage lighter total weight.
