Re: "unscrewing" plug wires. I drove a test light probe a few times between the wire & the coil socket the wire fits in to. I then gave it a shot of PB BLaster, which is great for, among other things, rejuvenating rubber.
This is false, I'm afraid.
I have PB blaster, and read the contents on the can. The part that makes rubber swell is Dipropylene Glycol Methyl Ether. This is a solvent, that leeches out whatever solvents are in the plastic or Rubber it is applied to. Any benefit from this application is short term at best, leading to an addiction to repeated applications. However, eventually the plasticizers in the rubber/plastic will eventually all leech out and be unresponsive to further applications.
PB Blaster is NOT safe for plastics and rubber unless you intend to discard it afterward.
(For instance, the O rings in the valve adjuster covers were flat, & not sealing. I dosed them w/ PB & they slowly swelled a bit, making a better seal. Its good for carb spigot rubbers, CV diaphragms, etc. But you gotta get them diapphragms back in before they get too big..... It dosnt harm plastic.
Yes, it does. When you get enough experience with it, you will understand this.
PB has great capillary action, & soon lubed all around the interface between the epoxy coil & the molded in plug wire. By twisting the wires on two, they broke easily & cleanly with the coils, & I could withdraw them. The two inners were more stubborn and are soaking, Ill give them a tug this AM.
As Bodi mentioned, the center conductor of the wire is soldered to the internal windings. If the wires pulled out, it broke that connection. Simply stuffing another wire into the coil hole, is NOT going to guarantee a connection to the internal wire. At best you will have another air gap for the spark to bridge, if the gap is small enough, it might work for a while, however, the spark gap will eventually erode the wire short enough, increasing the gap to the point where there isn't enough potential developed in the coil to jump the larger gap.
I figure if the new wire is too tight a fit, Ill chase the holes w/ a slightly larger drillbit....
That will make accommodations for the wire insulation, but not the wire center conductor connection.
I can't imagine this to be a trouble free repair. But, if you sell the bike quickly afterwards, perhaps you won't encounter these nagging problems.
Good luck!
