My 2008 electra glide classic has some slop between gears, like a rear wheel drive vehicle with some slop in the differential gear. Wondering if this is normal?
Not quite sure what the slop between gears is referring to here but give this a try to take up any slack in the primary chain that may be causing this sensation. I had something similar to what I think you are referring to here and this did the trick besides quieting things down too.
