Last night leaving Boston's, I had already gone 32 miles with the idiot light on (the furthest I've ever gone before was 36.4)... I was 12 miles from home, and knew I'd be taking a risk, but I wanted to see if I could make it. I kept the revs low (5K or under, & stock gearing), as I'd been doing since it came on, and it was highway almost the whole way so I was in 6th gear for most of it. I made it to the gas station by my house and the low fuel odometer read 44.1.
Holy crap! I never had any idea there was that much mileage left in the bike after that light came on! I should've checked my specs long ago (I just checked them now) and done some mpg math - specs say there's 0.87 gallons left when the light comes on (for the '02 R1).
The specs also say that fuel tank capacity is 4.49 gallons... when I filled up, I put in 4.384 gallons... so it looks like I was just about running on fumes!
What's the furthest you've ever gone with the idiot light on?
