Anybody know what the hell I should look for? I went on a 70 mile ride and including reserve, I ran out of gas. Never before, usually got 85 to 100 before reserve. No leaking, didn't run rich, started easy, just ran fine and most of the others I rode with had just under half tank. I thought a slight chance I forgot to top off??? but then I only got 4 miles on reserve. sum-ting-wong... I should get about 120 for a full tank. Actully, its only the 2nd time I've ever hit reserve on this tank. I do rides up to 80 miles before fuel stops, WTH! any ideas? this is baffeling me.
