I suppose it all depends on the performance envelope you want to have available. I found an Ivan's slip on (fitted by Falcon) improved it's low speed commuting manners remarkably. I got greedy and went for the full monty on a different bike. It came pretty close to mimicking an R1 I had at the time in third at about 8k on the rev counter. The front came up, and it took off like a scalded cat. Stomach muscles were used for the first time in years trying to hang on. Scared me a bit to be honest, as I wasn't expecting it.
Lost the licence shortly thereafter, so D666 kept the bike for me. It's got proper brakelines, screen, etc and a few carbon additions. I found the can it has (evo triangle thing) let it breathe much more easily, but I've also got an evo carbon straight through for silly days. Although those are mostly past now!
I had the back lifted, but found it very light on the bars in triple figures, so will drop the forks a bit. I'll probably stick to most speed limits now though, as Casey Stoner said to Rossi "your ambition exceeded your talent". I can't use anywhere near the full potential of the bike, so shock mods etc will probably go on the old age bucket list.
I'd ask Falcon269 for sensible mods catered to your riding style.
