I have my 70 Bonneville project on hold until winter, when I will start putting it all back together again. However, I am still thinking and planning. I remember reading a reprinted review article about the later Bonnevilles, stating that the gear dogs were undercut by a few thou's so they wouldn't slip out. What is the story here? Is it something that perhaps should be done? Or what years was this done? Enquiring minds want to know.

Upstate Trophy,

I think you are right about the undercutting of the dogs. I
would have to go look at an extra gear to be sure. But as I
remember it the driving face of the dog was at a slight bevel
to help keep it in under high load. I was working on my 79
when I noticed that.

And with a quick check yes they are undercut. But that is
all the information I have. As to when that practice started I
do not know.
