I never considered the CF wheels really. But after looking at the CF parts, I think some selective changes can look damn good, even though they are soo expensive.
With the Mandarin/Grey I think CF indicator pods, valve covers and alternator belt cover will already look good and blend into the colouring.
Since the front fender is CF anyway, it won't be strange to add CF to the bike in my opinion.
I found this site in NZ with some images of the parts. It seems terribly expensive!

I think the air filter is a quick, safe and noticible upgrade. So I'll probably do that. The bike is for street use only. I do some track days, but I use it often to commute (hence the stronger low-midrange and lighter weight). I have toured once or twice too, specifically for passes. My last one was 50 passes in 2 weeks. 8). So some handling would be nice, even though the boxer already handles so well. So for me torque is way more important than hp at the moment.
What kind of shocks upgrade would be good? Are you talking about the taller GS shocks, or something else?
What does the Techlusion FI controller do? A quick search seems to mention throttle response, which I assume means a bit better combustion and thus a bit more power.
Thanks for the cam sprocket idea. I will research that a bit. A small loss at top end is fine as I very rarely go over 200kph (125mph) and I assume a "small top end loss" translates to about 5kph (2-3 mph?)
