Thank you to everyone who responded to my question. Before I submitted this question, I read the FAQ in its entirety, and combed all threads on this site that I could find on the cam chain tensioner topic.
biltonjim asked me this:
"Please tell us about what motivated you to become a KZ1300 owner. Also, some photos of your bike would’ve nice to see, along with your experience of ownership. Thank you."
I have attached a photo of my KZ1300. I only recently purchased this KZ1300, the first I've owned. I have several original hard-copy magazines containing the initial 1979 tests of this model, to include Cycle, Cycle Guide, Motorcyclist magazines, and I have been searching for one since these tests were published. As you may surmise, I'm not very fast, but I am persistent! I own an eclectic mix of two-stroke, four-stroke and rare v-twin motorcycles, to include a Series D Black Shadow and a Ghezzi-Brian Folgore. Over the past month, I've put several hundred miles on the KZ1300 and I can say that I don't think I've ever encountered a smoother motorcycle engine.
Thanks again for the information. I'm still undecided as to how I'm going to mitigate the risk of the apparently poorly designed cam chain tensioner.
