Thanks very much guys. I appreciate the comments. She's been "finished" for a little over a year now and I've put about 2500 miles on her. Unfortunately, she's down for a top end overhaul due to low compression (broken rings in both cylinders) and new coils (splurging for Dynas). Hope to have her back together in the next few weeks.

I make things.
egads! if you've got broken rings the cylinders will probably need boring, chances are the sharp edge will start scraping deep grooves in the cylinder wall

Re: CB450 K7 "Espresso Love" (An update)
Well, its been along time since I posted here so I thought I'd give a quick update.
I finally got the top end rebuild finished and the engine installed back in the frame. The damage to the cylinders was a bit more severe than I had thought so I ended up having it bored out. After a lot of searching, I found a set of 1mm OS NOS Honda pistons and rings on ebay and had the cylinders bored to fit.
I was having a lot of trouble last year with an intermittent weak spark at the left cylinder, so I decided to upgrade the coils to Dynas. Also, because of the way my tank kind of envelopes the top of the engine, I thought it may be trapping a lot of heat and causing the coils to overheat so i wanted to relocate the coils to under the seat for better cooling.
After a lot of head scratching as to how I could mount them under the seat without interfering with the seat and tank mounts, I came up with a few brackets to mount the in tandem along the center line:
I made a simple bracket to mount the condenser where the coil pack had been:
So that's about where we stand today. While I've got the carbs off, I want to go ahead and take them apart and make sure everything's nice and clean and I'm going to seal the tank while it's off.
Maybe next week I can start her up and see how see runs.

Wow, time flies. I can't believe it's been over three years since I've posted to this thread.
I've never been really happy with the exhaust on this bike. Too loud, kind of a "raspy" tone, and maybe not the best performing either. I been thinking about building a little more traditional exhaust, so a couple of months ago I ordered some tubing, a few mandrel bends, splurged on a nice SS Cone Engineering muffler and started cutting and welding.
Got the new headers wrapped last night and went for a ride this afternoon. The tone is deeper and quieter, but there's still plenty of good noise when you roll on the throttle. I think it may have picked up a bit of power too.
Here's a pic of the old pipes and a few of the new:

My bike is not transportation, it is a respite
Very nice sir. I like how the headers follow the line of the frame.
