I just picked up a zx-9r and was out riding today when I ran out of gas and had to use the reserve to get myself to a station. I looked and looked but couldn´t find a fuel gauge. Is the fuel gauge on this bike/year digital or are you forced to gauge the trip odometer to know when to fill up. Please reply promptly as I´m suppose to go on a 2 hour ride next weekend. Thanks for your help.
