Hi Ted, i have done few upgrades on my rsv factory and this is what I would suggest.
Powercomander 5 with autotune AT300 you will have to take the exhaust headers off to weld the bosses in to take the wideband sensors but not a difficult job.
A Smalmoto airbox ring
Brisk plugs BOR12GLS only use the with Autotune as it runs fueling quite rich 13/1 AFR.
A quickshifter an ignition cut type
A quick action throttle, Accasato is a good one as it comes with cables and three cams.
All the above makes a big difference and makes the bike feel more current and modern also takes people by surprise. The pcv with Autotune makes it run so smooth low down that i changed the gearing from 15/42 to 15/40
as it was so easy to ride even in town and it wasn't reving its nuts off on the open road.
I did think of the flywheel but if eas to do it i would probably retain the weight but machine some off so it doesn't have the stalling problem at low revs also leaving the rotor assembly more secure.
I have also updated the brakes.
The engine is so responsive it revs like a 2 stroke and pulls from nowhere.
I hope this helps, here is a picture off mine.
