I've been following the threads on the Gen 4 Cam Chain Tensioner failures and was wondering what exactly is failing on the tensioner unit? It looks like a pretty simple and fool proof design and has been around for years but it sounds like the spring is weak. Is the unit actually failing or is it just slow to advance to the next notch and eliminate the chain slap? Have there been any reported engine failures from this, e.g. a loose cam chain jumping a tooth and causing a piston to contact a valve? Mine has been noisy for some time now and has not reset. I tried putting the bike in 6th gear and rolling backward and dropping the clutch but this had no effect. I removed the spring cap on the unit and tried manually advancing the unit to the next notch and that didn't work either. If it doesn't reset soon, I plan on getting either a new CCT or a manual unit like the APE.
