Will try to make this as short as possible. Have a noise that is driving me nuts. To start its sounds exactly like when my Inner Primary Bearing failed (cracked) and squealed like a unlubricated, metal on metal bearing. To be clear it is not this bearing as I did replace it and the sound is still present. For those with a good knowledge of the 2007 96 CI Twin Cam inner workings I'm hoping you be able to point me in the right direction. #1 The inner primary bearing is new. #2 inspected the clutch basket bearing, and the two transmission trap door bearings; they appear to be fine. #3 DID NOT yet pull transmission and inspect the most inner bearing of transmission next to front belt pulley; really hoping its not that one. #4 it only makes the squealing sound when bike is cold or has sat for 30 minutes or more. Once the bike is hot and run for more than 10 minutes the sound goes away. #5 driving over rough road makes it squeal more and again stops once the bike has been ridden for 10 minutes or more, as if it were a loose motor mount issue, but its not. #6 my uneducated guess… something to do with one of the hydraulic tensioners in CAM area or Counter Balance chain. I don’t think it’s a tensioner pad failure as much as maybe a blocked or stuck tensioner. Based on how the tensioners operate, if the tensioner was not filling with oil properly to tighten the chain or is just stuck in the chamber, the chain would be loosely slapping around in the CAM or balancer area and rubbing against metal ?? Running the bike will slowly allow the tensioner to extend and tighten the chain as it is supposed to and thus the sound goes away?? My thought is that a bad bearing in any of the various areas would continue to make noise even when hot? Thank you in advance for the person who either experienced this and fixed it or just knows based on what my symptoms are what it probably is.
