It's never too late to have a happy childhood!
Thanks again, guys! When I bought the bike the owner and I both thought it was a 750. Then as I learned more of the history, I was "certain" it was a 650. Then recently more history came up pointing that it might indeed be a 750 and that is starting to look to be correct. Frankly, it doesn't really make any difference to me, but it would be nice to know. One of these days, I'll open it up to be completely sure, but for now, this is fine.
