I’m in the same boat Jon. I only have two races left so hopefully it will last. Over the winter ill get a longer bolt and take the mount off the kart (hopefully onto a new chassis). Good to know I’m not the only one.
The first time I broke it the bolt went in from the outside so it came completely came out. Next time on the track I snapped two wires on the cdi box. Took a while to figure out the wires broke, sadly I didn’t know it was because of the bolt so I did it a second time.
