This is my second time running out of gas on the road. And when you run out of gas, it takes a couple hundred tries to re-cycle the gas on the reserve tank. My first one i had 200km for a full tank and i put in 87 octane. So i was confident that I would be able to run ~190km before running out of gas again, but the second time I ran out of gas i only did 174km... So I'm wondering why this is? I ride a 98 kawi ninja. I'm wondering if people who have ridden this bike had similar experiences, and how many kms do you run on a full tank before filling up again. btw, now I use 91 to fill up, and to be on the safe side i fill up when I hit 150km.
