Had similar problem with a vintage bike of 80's, drove me crazy, one of two problems, coil or CDI if equiped. Remove one plug at a time , leave connected to plug wire, ground plug against engine, try to start, watch for spark or color of spark if any. No spark could be coil, way to check is find one to replace it with and test again. same for CDI, it can't be tested only replaced. Also check with local dealer to see if the model had a recall for a CDI in the past, it may not have been done.
