Had a new expensive sounding noise show up yesterday, thankfully when I was close to home. Noticed it first when slowing to stop, sounded like a clacking sound, at first I thought it was something on the radio, turned that off and it happened again at the next stop. When I got home it would do it when rolling the bike backwards about 5-6 feet, it was a clacking sound and sounded like it was coming from just under me, I checked the belt the best I could as well as both pulleys thinking maybe I picked up a rock, saw nothing. Today I had a friend stop by with his jack, rolled the bike backwards and nothing, quiet (this I was not expecting). Raised the bike, tire turns free, can't feel any binds, all looks ok. Take the bike down the street, what I finding is that occassionally I'll get a faint clacking noise when starting out, however now when coasting I get a clicking and when I pull in the clutch it sounds almost like what a card sounds like in a bicycle wheel (only louder). Had my friend stand on both sides trying to find out what side it's coming from but it seems to be just as loud on both sides. Anyone have any ideas? I'm fearing the problem with the front pulley and/or output shaft (not under warranty).
