My findings about not very well documented stuff will appear here. They are subject to change. Updates every weekend until my setup is perfect.
Check out these pages for guidance:
London Bikers, suspension setup demystified and Bikesetup.com
Riding style and conditions: Commuting to work, either 15 minute ride through town or a 10 minutes on the freeway. Occasional wheelies to remind myself that fun's not over yet even though I'm 30+. Occasional 15-20 minutes of freeway ride, and B-roads every weekend or so in the summer.
5,0L/100KM Highway easy riding
8,6L/100KM Town commuting
Removing the tools and center stand saves 1,3 Kg. The OEM silencer weighs 7 Kg, and replacing it with a Yoshimura TRC steel sleeve slip-on saves 3,5 kg. Removing the centerstand also makes getting the sidestand out easier.
Rider weight: 110 KG + gear = 123 KG
Suspension adjustment fork:
One+ spring preload indicator decreases fork travel by 8mm. The manual indicates 5,5 "clicks" as standard, 6 is too soft for me, the bike dives too much.
Setup scenario: I want my bike to be a bit stiffer as for inspired backroad driving, somewhat like a sports bike, but not as a bench (read: Ducati)
5 is firm-ish, but it looks like there's too much travel way left, about 50 mm by eye-measure.
With the spring preload at 5, You will feel potholes as with a german car with stiff springs. The fork will be a bit stiffer, the bike doesn't dive as much under braking, and the ride will be comfortable enough. This setup will swallow speed bumps at ~40 km/h without a problem.
You might want to try 4,5 or 4 to harden the preload, and make the bike dive even less.
Compression damping: (left fork leg)
Standard is 5 clicks to the left. My setup is 6 clicks to the left. You'll want at least 6 clicks to the left if you're doing wheelies all the time. Landings are pretty hard otherwise.
1 click to the left is megastiff, like a bicycle. Speed bumps will be rock hard at 35 km/h.
26 clicks to the left will feel like you're jumping in bed, a jump, and you go up and down on the springs a couple of times. This will swallow the speed bump softly, but you'll bounce up and around after impact. Terrible sensation.
Rebound damping: (right fork leg)
Standard is 18 clicks to the left out of 28. My setup is 18 clicks to the left.
The standard is good for street riding, I don't feel the need to change it.
Suspension adjustment rear:
Tried 1+ preload, 10+ rebound. Bike spins on full throttle. Rebounds are too hard, you feel shocks in your back , even with smaller obstacles
Current setup: 3+ preload, 8+ rebound - default
Standard is 3 clicks, I run with 3 atm. I tried 1 click
Standard is 8, I tried 10, and the rebounds were a bit too hard, I felt the shocks in my back. Slower rebound can adjust chassis pitch, and slow down weight transfer to the front.

Fuel gauge issues
The fuel gauge stays at 100% for over 90 km, then suddenly drops to 50% and then makes another sudden drop to the reserve. This was resolved by changing the fuel pump unit which has the fuel measurement unit incorporated. Now the gauge goes to
-1 dot after ~40 km
-2 dots after ~70 km
UPDATE: My Yamaha shop changed the fuel pump unit, which has the fuel meter incorporated, on the extended warranty. It's all good now!
