The merits of this procedure have been well discussed elsewhere...if you don't feel comfortable doing it, THEN DON'T! However, understand that the microswitch on your kickstand with the associated three wires can fail at anytime, and will most likely fail when you are in the middle of nowhere, leaving you 100% COMPLETELY UNABLE TO START THE BIKE AT ALL. Secondly, even if the bike is running, the wires may contact each other and shut the engine off without warning. BOTH HAVE HAPPENED TO ME!! You don't want to be leaned over in a tight turn at slow speed when power to the rear wheel cuts out....not cool.
Anyways, if you can't possibly program yourself to double check neutral and kickstand before taking off, then by all means leave your switch alone (or replace it periodically). If you CAN, then by all means follow along with this video. Enjoy! Sidestand safety switch bypass video
