[QUOTE="Fred W, post: 1268890, member: 3828"] I remembered that yours had broken, and mentioned it earlier. You are right, it definitely shouldn't have. But in full disclosure, it didn't "just happen" did it? As I recall you had been "exercising" it because you had heard some cam chain noise previously. I am fairly certain that was the case with my friend ionbeam too. I fully agree that it is not the most robust CCT design. Some other designs I've been exposed to (mostly in autos) are far superior. But the number of FJR CCT failures is also relatively low with any that have not been messed with. And the newer paint dot replacements seem to have an even lower rate than the early ones. Nothing is 100% fail proof. Even your mechanical tesnioner the lock nut could vibrate loose and the tensioner would back off. I realize the chance of that happening is very, very (very!) small, but it is all just a matter of odds and numbers and percentages. Not that many have had problems with the shitty OEM design either. Of course that doesn't make the folks who have been stung by the stock CCT feel any better. And I fully support your encouraging folkls to switch to the mechanical device. But I''ll just take my chances (at least while I am covered by YES!) ;) [/QUOTE]
