My 2011 650 is new to me, and I've stalled it a few times mostly while dealing with hills in SF at low speeds. One thing I've noticed is an awful grinding sound at times from the starter when I try to start again. I think most times the bike stalled because I was in 2nd gear instead of 1st so I imagine it is in 2nd still if that matters, but clutch lever is pulled fully. It sounds like bolts in a blender and it might do it a couple of times before finally starting up cleanly. This doesn't happen every time I start after a stall, but it's happened maybe 3 times in the last 3 weeks. It's never happened when starting cold. I've searched the forum and other Kawasaki forums for similar sounds but haven't found what I'm hearing. Bike is at 37,300 miles and had it's major service completed recently. Any thoughts? Thanks in advance.
