1985 GL1200i

[FatBob]

I have just bought an 85 gl1200i. It has just over 28K for miles so I have lots of life yet. I have read a bit and I keep hearing about soldering the 3 yellow wires. What wires are they and why? I have the bike torn down right now while I am sealing the gas tank. I am rebuilding the carbs(carb kit), sealing the gas tank, new plug wires, new fuel lines, replacing most rubber fluid lines, etc. Any recommendations of things to do while its apart would be appreciated. This is my first wing and it has a sidecar since I am disabled so that I am still able to ride for years to come... hopefully.
