I'm having a bit of a starting issue on my K5. You know the "whirring sound" you get with first turning on the ignition? Well...it usually lasts maybe 5 seconds, after which the bike starts fine. But lately, on maybe 1 out of 2 or 3 tries, the "whirring sound" only lasts maybe a second or less. If that happens, the bike won't start. Cycling the ignition to get a 5 second whir will resolve it and the bike starts. I'm guessing the "whir" is the fuel pump pressurizing the line...but I don't know, so I'm guessing there might be an issue with whatever controls the line pressure. Any ideas about what the problem might be? I'd like to fix it before I'm left stranded someplace.
