I was out riding and the bike was shifting like a champ. Then suddenly, the foot shift seemed to be stuck in a downwards position. I could move the shifter up and down with my hand, but I could not get it into first. I rode it home in third and started adjusting the shifter up and down, but it is still not moving any gears. The green light does not flash as it passes through every gear as it usually does, and I can't get it into neutral. So, the bike won't start. Beyond the two rubber balls that have brass threaded connectors and the rod that adjusts up and down, I don't know any more about what is happening when the rod moves to shift. It's almost as if something broke and no longer moves when the rod pushes the lever. Can someone give some guidance. I can't even ride it to a dealer the way it is, since it won't start. Floyd
