I rode my 1999 prosport about 5 days ago and it ran great except for a couple of hesitations at mid rpm, kind of like a plug misfire. Now today no spark when I tried to start it. Any ideas ?
First check battery. Sometimes the misfire is from a low battery. Not saying it is, just have to start someplace. Take a multimeter, set it to 20v scale and read the battery. Red to hot side of battery and any good ground or on the neg post of the battery. What's the number?
I've concluded that my coil has died. I'm amazed how hard it is to find a coil for a 1999 prosport. Big Dog doesn't even have prosport in their list of bikes on their parts site.
