My '86 CB700SC (tariff beater for you non-US folks) had the maintenance free hydraulic tappets and the valves never needed checking. It had a much higher redline, too. The valves basically self adjusted every time they opened and closed. It was compact system, too, and would have easily fit in the existing head. Did Honda think we were so nostalgic for retro classics that we missed fiddling with the inner bits, too? Sad.
As for me, I dutifully check and precision adjust my valves via shim replacement every 8,000mi and set them back to center of spec... all the while wishing I didn't need to.
I haven't looked into what the Nighthawk valve diameter (and lifter) sizes were- but all lifters have to be a certain size for a given cam size- and valve size - and revs. As well as oil viscosity. Lots more to it than first glance.
That being said - I am still surprised nobody has done a Nighthawk knock-off with one of our CB. It readily lends itself- especially with the STD tank shape.
Staintune muffler looks right, the headlight shroud I see many people have looks right...hardest part would be tail section I guess...
