hello my dad had given me a 90 suzuki lt230 quadrunner. I brought it home and started working on it. Found couple of wires broken repaired them. Still have no spark. Started to testing I believe all tested ok. I think the cdi box is bad. The question I have is there a way to modify a cdi box. I have price a new one about 250 dollars. I really not wanting to that much in it at this time. Any help would be greatly appreciated.
