Like the title says no spark. I put a cdi box on it and after cranking then giving up it fired once then quit. This all started after a days riding then we took a break. Has not ran since. If you put the plug to ground you can see no spark when cranking. Also no voltage to the coil. There is no voltage coming out of the cdi box on the wire that goes to the coil. Help!! I do have some mechanical knowledge but this is stumping me. KIll switch stuck? Can you bypass these long enough to check? 8 year old wanting to ride.I need help!
