I use to use tractor supply plug wires, you could get a bock with enough to do 3 bikes for $15 bucks, but just last month I used the same wires (same brand same place I normally buy them) and found out they changed the material the covering is made of.. cause it melted right the fuck off..
Basically any SOLID core wire is what you want.. You might try the tractor shop, I may have just got a bad batch on these plug wires... prior to that I had been using them for years.
