...starter spins fine but it will not turn? it will not turn over. When this happens, i leave the bike for a few hours, come back and it starts right up no problem..Also when i try first thing in the morning or late evening to start it, it spins, lets out a quick sputter or cough, but than after that it will only spin and spin, it refuses to turn over. Please help! Why does it seemingly randomly refuse to turn over??
