Coil Mod

[Scottie1]

I have been having a extremely hard time starting my 86 FJ1200 recently. The carbs where rebuilt bye RPM so I know they are 100%perfect, valves in spec and also a new AGM battery. I could find any other route to go down to try and figure it out. So I done the coil mod as a fair few of you all have done and low and behold the bike starts first time every time now. I wouldn't of ever thought about doing this if it wasn't for this great forum.

Scottie,

I work in electronics.  I wish I had a dollar for every time a tech came to me saying that something did not work right, and we found the fix was to "improve" on power and/or grounding.

Most bikes have pathetic grounding, maybe through the dull-metal frame, or by undersized wiring.  I agree 100% with your experience; before changing the expensive parts, add good solid power and grounds.  Dull and corroded metals make very poor ground connections.  Shiny-bright and bolted tight should be the way to go, there.
As a side note,    "ground" on a motorcycle is really just an agreement among humans about where we connect one side of the battery.
