for the last couple of months, every other week or so, when I try to start my M109R I turn the key the battery engages and I hear the electronic hum as it cycles up, but when I press the start button nothing happens, as if I have the kill switch engaged, or the kick stand is down while it´s in gear, but I don´t. Usually I can get it to start if I shift into neutral and back to first gear, but the other day I had to get a push start. I´ve checked the battery and it is good. Any ideas?
