There’s lots of chatter on the ‘net about failing cam chain tensioners for pretty much every bike out there but the thing is there are very, very few actual FAILED ones, just noisy. So my suggestion is to change it when it gets rattly to the point it bothers you and not at a set mileage.

And I prefer the OEM ones over the manual ones. It’s not rocket science to adjust a manual one but after reading probably 1,000 posts of people that have swapped them for manual maybe a dozen actually installed and adjusted them properly. It’s VERY easy to over-tighten them because everyone wants no noise since that’s why they swapped theirs out. Thing is, that’s too tight which causes accelerated wear on the valve train components which is why people supposedly swapped the loud one out but loud and slightly loose isn't hurting anything but your ears like the too tight is……….

And that’s why I recommend another OEM unit.
