Guys, do these batteries fail so completely, that even if you jumped it, it stopped as soon as jumper is removed? OK, I'm pretty certain that the battery is dead, but usually (historically), if I was able to get it started, at least I could ride it home. Today, my 2000 Busa quit. OK, I really didn't tend to the battery all winter, but it started fine when I left the house. After 40 miles or so, it quit at a stop sign. Probably not the best thing to do, but I jumped it with a truck (I'm going to get slammed for this . It started, ran fine until I took the cable off, then nothing. Do you guys think the battery is so completely dead, it won't even keep it running after it was started again? I tried it twice, both times it started fine. As soon as the jumper came off, it died. I had to get this thing off the side of the road and ended up putting it in the truck. Usually, even if I could bump start it or whatever down a hill, it would still keep the engine running until I got it home. Thanks for any clarifying information. I've had this bike for ten years, and have put 2 or 3 batteries in it, but never has it failed such that I couldn't find a way ti start it, and take it home. (Only 18K miles on it). It has never had any other failures.
