As you roll it back and forth push the shift lever down. Once you hit first gear it will not push down very much, now pull the lever up a bit, this should be neutral.
If your neutral light lights no matter what gear your in check the sky blue wire that runs from the neutral light down to the neutral switch on top of the transmission. If it has a frayed spot that touches ground, the light will light. Power goes to the neutral light on the brown wire, then runs from the light down to the neutral switch on a sky blue wire. In neutral the switch grounds the sky blue wire lighting the light. Any shorts to ground on the sky blue wire lights the neutral light.
Finding neutral as I first described will find neutral even with the key switch turned off.
I don't recall the exact reason but even in neutral as you roll the bike backwards there is something about the kick start that binds when you roll backwards. The kick start works by engaging gears in the tranny to turn the tranny main shaft that turns the clutch hub that turns the outer clutch basket that engages the gear on the crankshaft. As you roll the bike backwards the gears engage and try to spin the kick start backwards.
This has no effect on the kick start or e-start.
This won't prevent safe operation of the bike.
