I will never start a computer bike running along side of it. Inline-4's I find 3rd to be the compromise. You run a points/condenser bike it's every 360° is the points fire.To bump start anything, you want to use a high gear...try 2nd or even third... It's not like the old school shit...
Kawasakis have had what they call a positive neutral finder for many years now.I push started the beast 3-4 times last summer before I finally realized my fresh, couple weeks old battery had died. Couldn't believe it at all and went through all the electrics, stator, rectifier etc..
Anyways 2 times my friend helped to push and it did require some speed before it worked.
Last time I had to get it running by myself (was in a hurry to work) and I dragged it uphill, got as much speed as I could and at the bottom released the clutch.
Also the bike wont let go to second gear if there ain't some speed on it.
1 variable says a computer bikes need over 12v to keep 5v alive in the ECU. Do the math. Anything under 12v, the ECU won't work with 4v at the ECU = No start.
Go back up and reread AFKAN's post. No need to take anything apart...I would have jumped it, but I to get access to the battery I will need to take so many things off!!
I also left the top bolt of the battery cover off the last time I was in there, and now I can remove the cover without removing anything, but still not enough room to slide the battery tray out or stick jumper cables in
