Best way to ground motor to chassis?

[Newcs222]

I've recently done a new motor install. I painted my frame and forgot to sand the areas where the motor makes contact with the  frame. Now I'm getting weak spark. Whats the best way to ground the motor to the frame? I don't wanna loosen the wrong nut and get leaks.

ive never sanded anywhere on my frame should be grounded threw the harness and unless your filled the threaded holes with paint its ground threw every bolt hole

<p>One heavy gauge wire from one of the center head nuts routed to a sanded area of the frame where the coil mount bracket is.</p>

Lots of photos of frame/motor grounds. Some are pretty clean looking.

One day I will get around to shortening it.

But I got mine at Walmart. It was in the auto section. It was a starter ground wire, it cost like 4 bucks.
