I have a 2008 Kawasaki Vulcan Nomad 1600, nudging 35,000 miles. Up til now it’s been trouble-free, but a month ago it wouldn’t start up. I figured it was the battery (original), and the mechanic concurred, given the age, mileage, and the fact that the bike has spent most of its life in Texas and Southern Arizona. We replaced the battery, but even though the starter worked fine, there was no ignition. Fuel was simply not getting to the cylinders. A peek inside the tank showed it was clean as a whistle, so the mechanic towed it to his workshop.
