Hi Everyone! I have a 2009 Vulcan Classic LT 1700 with about 35,000 miles. I bought it used from a dealer about nine months ago. I ride it everyday and put on about 90 miles each day. I was driving up a slight grade at about 75 MPH when I heard a "POP" and immediately following was the sound of something spinning hitting a fixed object. Another way to say it would be like the sound of a card rapidly slapping bicycle spokes. I did not see any liquid or smoke nor did the bike lose power. At first I thought I hit something and it stuck to my front wheel causing the rubbing sound. The sound stayed with me until I stopped the bike at work a few miles down the road. The bike was parked all day and when I got on it to go home the rubbing sound was gone, but I now have a rattle coming from the lower front area. It sounds similar to the pinging noise the engine makes when accelerating after using bad gas except I hear it all the time now, even when idling. It's not very loud, but I notice it. Any ideas?
