Well I don't lube it as often as I should or at least as recommened...Probably supposed to every 5-600 miles right...Well between washes, rains storms, ect I supppose it gets it every 1000 to 1200 miles...I have noticed it was not staying well adjusted too. I had recently tightened it and adjusted it 2-3 times cause I couldn't get it just right...That was when I decided the rear sprocket had to be replaced.

The noise sounded like a bearing gone bad. Kind of a marbly grinding noise...The first thing I thought was that the chain had loosened up and was hitting the front cover, upon seeing that is was still tight I thought immediately wheel bearing, but all the bearings appear fine. I didn't get around to reassembling it but will certainly soak the chain and see if it loosens up..
