Dennis, disciple of the Mighty K8 - a couple of thoughts..
With the settling into harness at work and your new young family, if the process is anything like most married guys , I understand completely the changes happening with your lifestyle. When it was just you and your wife, you were #1, then came first born and your instant demotion to #2. Then second child and to the bottom of the pile. Family unit priorities changed too. The new washing machine jumped to the top of the list. And the education fund, the kids bedroom furnure, the trip cross country to Grammas.... You are off on a grand 20 year adventure that will have some of the most rewarding times of your life. Be sure to enjoy it. Believe me, your kids will be grown and gone before you know it.
Your K8 is the final version of the mighty CB750Ks and has special place in mc history. You have already paid for it and the money is spent. There isn't enough money in the bike to make the slightest impact in the family finances long term. If I were you, and was burned out on the project, I would take a break- prepare it for long term storage, put all the parts in a box, find a covered secure shelter, put a good tarp on it and forget it. No big deal if its out of sight and mind - there
will be a day, maybe even 20 years down the road, when the time is right and you have more free time to spend on yourself. It is likely at that time you will have increased earning power and fewer expenses. Maybe even nostalgia for your young manhood.

The K8 at that time will be far more valuable to you personally than the few hundred bucks you are seeing in it now. Thats my humble advice, and I would also be discretely buying any missing or damaged original pieces on eBay that would make the put- away package complete.
You could show your everloving a few sandcast auctions to illustrate what is happening to some sohc bikes now. I expect the return on your investment, over the next years, even a K8

, will be one of the better deals, percentage-wise, that you will make. Yes, keep it. David
