Recently picked up a 2013 RG Ultra. Been riding mostly Dyna’s & Softails...This is my first touring bike, 1st fuel injected and my 1st with a 6 spd transmission. I’ve noticed when I let off on the throttle there’s a clunking sound. I’m not bogging the engine down and the RPM’s are staying up. I’ve never noticed this on any of my other bikes. Is this normal or is there something I need to look into?
