I am looking to put a little 3 gal aux tank on my R1200GSA and was wondering how you go about making SURE you don't go over the required 11.5 gallons. My tank is 7.9 gal and I was looking at either the 3 or the 3.5 gallon aux but the 3.5 puts me pretty close to that marker. I don't have any idea how much fuel is in the fuel lines and I know that is part of the calculation.
What do you do to test your capacity?
