Hey guys, newer member here. So last week I changed Primary fluid last week and when doing so i noticed the primary chain had a lot of slop in it. I tightened it back into spec (5/8-7/8 for my dyna) and away I went. Took it on a weekend trip (600mi) and on the way back I started to here this noise from the primary. Sort of clicking /grinding noise. Happens all the time, does not change with rpms, gear, clutch in/out. Even with the bike off and in neutral it can be heard when rolling. I got as far as pulling the primary case last night...attached is a video of the noise. Sorry in advance for the shaky quality but the noise can be heard pretty clearly.

Any advice would be welcome before i dig in further....
