Went for a short 90 mile today, beautiful weather... The bike was running great but when I stopped for fuel I became a bit concerned. When I went to start my bike (neutral) it responded with a fairly loud series of clinking and clanking from what sounded like the tranny area, maybe even up front in engine, not sure. As it made an unusual and frightning sound I let off the start immediately. Bike sounded like it tried to turnover but failed. I may have not gave it enough time to turn over, all I know is that I immediately let off the start switch. Went to try it again, this time a bit more prepared should something out of the ordinary occur. The bike started but it still sounded a bit off as if something was slamming together at initial start. Got home and she starts fine. Any ideas?
