Internal, no maintenance nor settings, meant for the life of the engine apparently, though admittedly this Honda V is no where near a rev monster.

I really like tensioner design on my Honda V4. It's curved steel spring with plastic slipper surface that presses on cam-chain over 6" section. Large contact-area reduces load and creates high durability.
Another concern is harmonics in sections of chain around contact point. With small single-contact point to adjust tension, you end up with harmonics on either side based upon engine-RPM.
