Hey everyone. Just found this issue after getting my ass kicked by a cylinder randomly dropping out on a bike with no codes showing.
This is the factory coil wiring. It’s
retained with a Christmas tree zip tie and then folded back on itself and zip tied again. Bike was randomly dropping a cylinder with no codes. Thought it was in my tune, kept checking, wasn’t finding anything. Happened to push on this plug while the bike was running (thinking I didn’t have it snapped on) and both cylinders started firing, let go and a cylinder dropped out. Found this when I pulled it apart…
Three of the 4 coil wires broken. So, I recommend if you have a 23.5-up center cooled touring bike, you cut the bottom zip tie that is folding the wires back over. Just passing this along to hopefully help others.
