Another idea is installing a push button neutral safety switch.
I installed one so I could start the old VH 9 in gear, this allowed the transmission to warm up faster on our - 40 mornings.
Actually one of the factory upgrades for the VH-9 caused engagement grinding unless transmission was warm.
Worked well I might leave it wired up as it is just a jumper between two terminals in the front panel. short piece of wire and a spring loaded button.
Your just pushing two buttons to start. Theft device also
