Being kind to my 803cc engine. Suggestions?

[stopintime]

I've more or less decided to keep her for a long time, so....

At +30k miles I'm thinking about internal work.
My goal is to have the engine spin effortlessly = performance and longevity.

I've been told changing the (dual mass) primary gear is a good idea.
Getting "everything" within spec.
Balancing crank, maybe a lighter flywheel.

Then there's head work...

Any input?

I like the light weight flywheel, but that's something (as well as most other engine mods) you should do when the bike needs service anyway.

Why not light weight wheels first?

Who said I can't have both?

buy a used DS1000 motor withonly 5k miles on it!

Could, but I want it to be smoother than stock and I think a 1000 requires harness, ECU, exhaust bla bla

money no object engine build...

low end:
knife-edge lightened balanced crank
TI rods
HC pistons
large gears lightened
lightweight flywheel

heads:
port & polish
larger valves
new valve guides
new seats (if needed)
increased intake diameter

intake system:
larger throttle bodies
larger lighter airbox or pod filters

I'm listening 

Rough estimate?
Where/who?
Result?
DP ECU sufficient?

you have a mechanic you trust?
whats your spending limit and where are you going to get your parts from?

I had a Nichols Flywheel on my old monster. As is generally the case, the lightened flywheel makes the bike rev up much faster.  What people dont tell you is that is the increased revs also burns the clutch out faster. I noticed a lot of clutch slippage on my old M800 after 17k. My S2R 800 is running strong at 25k with no signs of slippage (stock flywheel). Take that into consideration as well. You indicated longevity in one of your posts so I had to bring it up.

Assuming you've got a moderate budget for this...

Balance crank.
Re-shim transmission shafts as necessary to get end-play to low end of spec.
Re-shim crank to reduce pre-load on bearings.

Get valves and seats freshened up with light cuts, and a bit of port work in the seat area.

Hi-comp pistons.

I'm not a big fan of light flywheels, but lots of folks like 'em.

I'm not limited, but I don't want to spend a lot to gain little. Probably in the area you're describing.
Starting off second bike chapter with a refreshed engine which will rev willingly and be happier at higher revs. If I get a little added power, that's a nice bonus.

Light flywheel is not a priority.

HC pistons? Which ones? In your opinion - why? New/better rods required?

You're going to send me the parts, stupid

as much as i would like to say we can do it here... Ducati Kaemna is the shop you need to look at for a money no object build

I object to the "money no object" theory 
This autumn I can spend, but I won't do it just to get rid of money.

If I can have it done for ~~ 3 to 4k 
If it's much more, I'll have to think twice.

_will travel abroad_

Kaemna is like a smorgasbord!

It would be worthwhile to talk to Kaemna.

Throttle bodies are all the same up to 1000cc on the 2-valve ducs.
Unless you're planning to make a *lot* of power, I don't see any point in the 50mm throttle bodies.

Kaemna has very nice Pistal 88mm pistons, I suspect they'd work nicely in your 800, but check with them to be sure.

Talk to your mechanic about what it will cost to remove your engine and split the cases, that'll help to see how much of your budget is left over to buy goodies.
