steve.1995 Posted February 14, 2012 Share Posted February 14, 2012 So i recently brought a Yamaha dt50 Mx. It was in a bit of a state so i took everything apart and resprayed everything and had to get the swing arm welded. After putting it back together i have found that the bike has no spark. The bike is the cdi version which has no points. I have checked all the wiring and everything is in its correct place. I have also brought a new ignition coil and spark plug and still nothing. Has anyone had any similar problems or any info that may be able to help me? Thanks Link to comment Share on other sites More sharing options...
