Joined to find tech info. Have a 15 year old FLHPI with some minor (I hope) issues. Hoping to be able to get some ideas on keeping my baby up for another 15 years or so. Right now, I have a metallic sounding racket when riding. It increases with engine rpm but goes away at higher rpm and when clutch is disengaged. I do not hear it when stopped or when transmission is in neutral.
