I also repaired and added quite a bit to my 77" HONDA CB550k. They seem too suitable for OEM terminals. And come with 3x wire size. I don't know how weatherproof they are, but I have them used in the headlight and under the tank, so it's not right there in bad weather. But I like heat shrinking, but it's also quite difficult, try to remove the cap, solder and put it back on. I just used the back of the Pliers used too hard. Their heat is slowing down so don't burn them. And it's pretty good…
