If you're still looking I have a massive screen specifically for the S200.  A bit less sure on the hardware since it's been a few years, but definitely have the screen.

Wish I could give ya a straight response, but I only almost bought an AK, instead I picked up the last year of the AN650.

With that noted. I picked up the Bridgestone Battlax Scooter SC2 Rain tire for the big Burger and have been delighted with 'em.

Poke around the various forums and reddit of course. Caveat Emptor etc. They're not cheap but I suspect you could do worse.

I've used fancy ones like that.
They're great but I fear I'm better off with a box of packaged foamies.

Nice though.

My latest earplugs are these babies:  https://www.amazon.co.uk/EarPeace-Motorcycle-Ear-Plugs-Motorsports-Black-Case/dp/B076VVV5WJ?th=1

Been using them for 2 years now and they are both comfortable and effective.  Not the cheapest maybe, but you get what you pay for! 

How do I manage not to lose them?  Now that's a whole other post about turning every ride preparation and end into an OCD sufferer's dream / nightmare!

If that doesn't work, or you have some around, hit it with some Plexus. 
Stuff isn't cheap, & it's kinda rank when applied, but I've had reasonable success on scratches on windscreens. 
Didn't obviate them or buff them out of course, but did clear them aesthetically to an extent.

I'd think any of the 300ish mini-maxi's would be a bit quicker.
Other than that there's not a lot around (new) that falls between those two choices in the U.S. at this time.

Another thought though, having test ridden the ADV 160 & kooking at the spec on those, noting it's similarity to my SYM I'm curious if you've tried dropping a gram on your rollers?
I did this with my SYM, & might have lost some hypothetical top end, but gained a better real world top end as well as better acceleration.
I tried both sliders and rollers to achieve this & found the DP sliders were a better fit for my application.  The rollers had the engine very revved at the top end where the sliders calmed that down somewhat.
Caveat Lector, & I suggest you check the Honda forums to see what others have done of course since YMMV & these are different bikes.

I went all LEDs on the SYMs, & filled in the Euro lights in addition to keeping the stalks for blinkers.
Also added a Shad case light for extra visibility and an eye catching change when braking (The Shad light is not a running light, it only comes on when braking)
The difference on both ends is amazing.  If you can't see it, you're not looking....Which is sadly sometimes the case.

I doubt it'll be an issue.  Even Mfr's say 5 years.  Chemists say 15 if ya dig around, but the standards update periodically so it won't be the latest greatest  Of course your bike is likely older than the oil that should be an issue since it was built to the older standard.

Google around a bit and see if you're comfortable using it.
If not. Gear oil is cheap, drop the old stuff at the local hazmat for recycling.

Very nice.
Almost bought one of those.
