Hello, I am new to this forum and would like to try to figure out what is wrong with my (semi) newly acquired bike. I bought the bike about 2 months ago and up to now it has run perfect, about two weeks ago though it started acting up. I had just gotten home from a weeks vacation and wanted to go riding but the bike wouldn't start, I thought this was very odd as i had just ridden it the week prior to when I had been gone. I got a new plug for it figuring that it was just flooded, stuck it in and still wouldn't go. That is when i decided to check for spark, and sure enough there wasn't any. I have already checked the grounds and cleaned out the cap connection, as well as ruling out a bad kill switch. Now I am quite confused as to what would be causing this? Is there a way to test the coil? I am pretty handy so I would like to try to fix this myself if i can! Any help would be greatly appreciated!!
