Yes, the kill time will be adjusted with R1. But next you need to measure the side stand condition.
1) is G shorted to ground to run or to kill?
2) when the connection to ground is made, how much current flows to ground?
You see, the circuit is actually designed by thinking backwards. First, what has to be controlled, then how do we control it, then how do we make sure the nasty, noisy, motorcycle generator voltages don't eat the brain chip. After "what gets controlled" and "what will control it" gets done, the answers are apparent to the question, "how to safely feed the controller how much voltage and how much current".
I'm not talking about the shift switch and capacitor yet because they are easy. Feeding the G pin to ground is what I don't know.
