Well theres your answer learn what you're doing and you wont have any issues lol
Exactly. The problem is there's a lot more people who get that wrong, than right. All you have to do is pay attention to all the threads on chain maintenance..... that's even easier to see, and people F that up all the time.
The accelerated wear is not immediately apparent. It becomes a latent fault. I do not recall having a fault with a chain driven cam, in all the bikes I have owned. That's now been 6 or 7 bikes so equipped, with a minimum of 25K miles on any one of them. (as much as 53K on the highest mileage unit).
Cam chain noise doesn't really bother me..... a ticking motor doesn't, either. I don't expect reciprocating engines to be quiet, or vibration free. They are far less obnoxious in these regards than they were even 30 years ago, and much less maintenance intensive.
Non linear clutch springs for low effort levers, slipper clutches, EFI..... O ring chains, truly superb suspension action, great frames, wheels, lighting.....
So much better to leave them alone and just ride the things.....
