Today after i did a oil change Put the bike on the center stand to run and check for oil leaks. I also swapped out the rear brake pads which needed changing ( bike has around 30K on it). I put the bike in to fist gear to check the brakes and heard a clacking type sound coming from the rear end. Took it out of gear and shut the bike down, checked take I had gotten the rear pads in correctly. Started the bike again no noise, shut it down and tried it again noise was back. Putting my hand on the finial drive while hearing the noise I could feel some knocking in the housing. Anyone else come across this?
