I don't think mine has failed but its still got a way to go on the auto adjustments but in a year it still hasn't moved to the next stage so still rattles until warm ?
Unfortunately they do that. How you ride may be an added factor as well.
The last time i had cam chain noise it took a good part of the year before one day, when i was just leaving work and letting the bike warm up there was suddenly......silence.
I was so used to it chirping away that i thought something was wrong.
Been doing it again for a few months now (a few years later) but i don't do high mileage and get stuck in a lot of work traffic most days so i just expect it to take longer than normal to click.
As for one of these gagdets i'm hearing very mixed reviews. They probably work fine as long as they're not over adjusted which could result in more bad than good for the engine.
