350x Has marking on CDI box?

[resqtool844]

I'm putting back togeather My 86 X that I've totally restored back to original as close as I can and while cleaning up the CDI box I see "comp 2" etched on the end of it... Anyone seen this before? I didn't know if they can be modified for racing purposes or not.

CDI can be modified,I had one that was drilled to remove the rev limiter on a 250x
