It did say in the B1 Book that you had to disconnect the 9 pin plug inside the headlight so that there would be no load on the charging system! But to start the bike You had to unplug the 3 pin plug of the Regulator (Green Brown & Black wires) and Bridge the Brown and Green pins with a wire.
Warning!!!
A) DO NOT LET THE BIKE REV OVER 2000 RPM…This may cause Damage!
B) DO NOT USE THE ELECTRIC STARTER!
KICK START ONLY.
I would study a B1 Manual.
