Gas Mileage
My 2017 GSF is having horrible fuel economy. I have modified the full cat-back but something is off. I average around 350km per tank... but I am quite sprited in driving.
Wondering if the car is getting older at 50k (km), or is it the old spark plugs that is causing this problem?

Without taking the car on the highway, I’m getting 16-17mpg and about 230 before the low fuel warning comes on.
I don’t mind the mpg with this type of vehicle. Wish the tank is little bigger though.

That mirrors my experience and wishes. Another 4 gallons would be really, really nice.

The gsf tank is 17.4 gallon. I believe The light comes on early. I think around 12-13 gas. Which means you have another 4-5 gallons to go. I routinely drove my Camry 80-100 miles after the gas light comes on and the gas needle is typically way below the E (empty) sign. I have not pushed my GSF too far below 0 range but pretty sure there is much left after the light comes on. Just note how much it takes at fill up and subtract that for 17.4. to see your reserve.
My GSF came with a stupid spare tire that protruded into the trunk! On normal GS cars, the tires are below the trunk.
My C63 AMG has a 50 liter tank, while my wife's C300 has an 80 liter tank!

I have noticed a couple of MPG drop recently as well.
