After my last race two weeks ago i replaced my broken battery box. I found that it would not keep from blowing fuse #2. Finally figured out that I had mud in my idiot lights that I had taken off the dash taken bulbs out of and zip tied under hood. Fixed that and now I cannot get any spark. I have two 450s and have swapped everything out. After a harness changeout and cdi swap, I actually got it running, and then it, the spark, went away again! Anyone have any ideas? Also changed stator, pickup coil, coil,all tps sensors, I am out of options.
