Hi Hobiercr,
First, let me begin by saying how much I admire your mechanical skills. I have known Jack's K0 since the 1970s when I was at the University of Florida. I also had a K0, that was not nearly as nice as Jack's. I liked his so much I took several pictures of it as it sat in the Library parking lot.
Imagine my surprise when I saw the bike 25 years later at an open house event at the Honda training facility in Alpharetta, GA. At this point, I still had no idea who owned it. About 5 years ago I saw the bike again sitting outside R-Speed a Miata only service shop that does all the work on my Miata. I finally met Jack.
Fast forward a few more years, and I learn about Jack selling the bike to Brian Fuller and about Brian's plans. After grieving for a while, I called Brian and asked if I could purchase all the unused parts. A deal was struck, and when I came to pick up the parts, I learned he actually had parts from several CB750s and I was getting them all.
What a haul!! But the point of all this is among the thing I got was the gauges - the one's both you and I grimaced at when we saw tossed so casually to the ground. The lens of the speedometer was badly cracked. Fortunately, I was able to repair it! I removed the case and carefully broke out as much of the lens as I could. Then I chucked the case in my lathe and cut out the remaining pieces.
I got a piece of 1/4" Lexan cut out a circle, and machined it to the proper diameter. Next I reduced the thickness of the center to the proper thickness for the lens while leaving the lip that positions the lens correctly in the case. I polished out the plastic and the lens looks good as new, and is probably more durable than the original.
Oh, and how do I know of your exceptional mechanical skills? I know CB750s. I've owned them for over 40 years and am currently rebuilding two of them. I've been buying parts off of ebay for these bikes for years. I couldn't believe it when I saw the carbs from Jack's bike. Every nut, bolt and washer on the carbs was original. every hose and clip was in place. In fact, every used sub-assembly I got from that bike was exactly as it should be. Many were showing the wear of 40 years, but there was absolutely no jury-rigging or missing pieces. That doesn't happen by accident.
Well, anyway, I just wanted to let you know that much of Jack's bike will live on, and that I appreciate your contribution toward keeping all these wonderful and hard-to-find parts in such exceptional condition.
By the way, I grew up in Holly Hill Florida, two blocks from what is now the Grassroots Motorsports showroom on US1. Back then, it was a Planter's Peanut store.
