I have a 2001 Kawasaki ultra 130 that ran great last time I had it out. I just went to take it out to the lake again and it was very hard to get it started and keep it running. After I finally got it running it only would go about 15mph and the warning light flashes and the battery light is on...runs kind of rough, a lot of sputtering trying to start. what could be the problem?

 

Check your spark plugs..
