I noticed while riding my chain seems to sound like its grinding. I've checked the slack, its fine. Its still lubed from when it left the dealer. So why is it so rough sounding? Has anyone else had this issue or is that how its supposed to sound?
The little "laser lights" used as pointers (and cat exercisers) and in at least a few levels (I borrow my wife's Black and Decker level) are excellent for checking the alignment before side panels/chain guards, etc. are re-installed.
