Hello everyone. 2007 fatboy. I'm having an issue with performance. When running I remove the rear plug wire and has no effect on the engine. I checked the wire resistance and on the 20k setting I'm getting 4.xx ohms, I'm assuming that is 4.k ohms which would be in range. I plan on changing plugs and wires but I am trying to isolate the exact issue. Compression on the rear cylinder with a rudimentary setup yielded 120psi and would be higher if completely sealed. I removed both plugs, connected to coil and could not see a spark of there was one. Used a screw driver, grounded and saw spark and it was a orangish color. Of I remember the spark should be blue or white? Got a shock the other day and I'm no spark tester but it didn't seem as strong as I thought it would be. I'm working on a limited budget at the moment (i know) so I will get an electrical manual when I can. I'm thinking it's the coil, plugs, and/or plug wires possibly. Any help would be greatly appreciated.
