i have a DT8 suzuki. I think it is a 1980's model. it was running like a dream. BUT has now stopped sparking. I have changed the plugs,the HT leads, the coils , and the condensors. all the wiring inside the flywheel has been replaced and there are no broken wires or kinks. It seems to spark most of the time on one lead onlt. There is no spark coming from the live wire from one of the condensors, i have swapped the condensors over and the problem still persists,any help greatly appreciated
