Thanks for the feedback Keith! I don't think it's a lifter. The sound is more like a belt or chain slap. It's not a ticking sound and it isn't rhythmic at all. It's more like rattle................rattle.......rattle, rattle, rattle .......................... rattle .................................. rattle, rattle .................................................. ................... rattle, rattle, rattle rattle ............. Heading out for a bike ride so I'm going to see if unplugging the adjuster makes any difference other than giving me a code for cam not advanced.
