I’ve had issues with my gt motor wires breaking at the bullet points as well, as they got older the motor leads gradually got shorter and shorter.That’s probably it. I was looking at the bullets and a few of them had some other gunk on them, and the one I re did the 3rd hand I use had tape on the holders and that melted into the connector. So I’ll probably take it to the shop to have someone do it better. But I’ll still probably buy another one just in case and if I ever do get around to that twin I want all that power to thanks!
