I have been using Techron regularly for over ten years in my 94 R1100RS. I usually go through two bottles of Techron per season. In 170k miles I still have the original fuel pump, fuel regulator and fuel injectors in the bike. I have never had the injectors out to be cleaned or flow balanced, and the bike idles smoothly and revs up great. So I do think Techron is a great product for regular use to keep the fuel system clean.
But to expect it to keep the combustion chamber and piston crown free of carbon buildup is an unreasonable expectation in my opinion. The Autolite plugs on my RS always have a great light tan color to them. But when I shine a focused light beam into the plug hole I can easily see carbon buildup on the piston crown. Very minimal, but it is there. Although the carbon buildup is not thick or crusty like in some carbbed cycle engines I have worked on over the years.
