I would suspect the handlebar starter button which you are replacing.Two days ago I was involved in an accident that resulted in my handlebars facing towards the left, and my front wheel facing slightly to the right, (the trip tree was snapped off at the crown and bent on the bottom); the bike wouldn't start. I replaced the trip-tree, forks, and rebuilt the dash; all the elec's work.
My problem is starting. She starts perfect when I use a screwdriver and make contact to the two solenoid screws (underneath right side-cover), but she wont click when I apply the starter button. Upon disassembly of that starter button, the spring within got lost somewhere within the engine; thus I'm presently working of getting a new/used switch (posted elsewhere).
Can I please get some input as to where my starting problem may lie?
NOTE: the accident happened 4 blocks from home; she wouldn't start (not even click). After being pushed two blocks, I tried starting her again and boom, she started; I rode her two blocks home (twisted as she were); turned her off, but again she won't start unless I use the screwdriver/solenoid method. Ride safe.
