Sorry to hear that you are having problems with your bike. I have few questions for you.
-Does the loud electronic whining sound seem to be the starter motor spinning but not engaging?
-When you try to start the bike out of neutral, do you have the clutch lever pulled in and the sidestand in the up position?
-When you tried to bump start the bike, did the bike seem to have compression?
-How were you adjusting the timing?
