Its the switch that I cut, there maybe a different way of doing it but I think its probably the easiest, the switch needs to slide out a certain length so that you can start in gear with the clutch pulled in so I snipped about 1/8th - 3/16ths of an inch off it ,and it worked on any adjustment setting on the lever ( ! to 6 ) just be careful to leave some or you'll be able to start with the clutch engaged

If you kneel in front of the clutch lever pull it in, it will be easy to see the switch slide out against the plate of the clutch lever.
I have heard of people who have taken the switch out completely- I know pulling the clutch in should come naturally but on balance Id prefer a fail-safe

The amount of times I've been rescued by the side-stand cut-off switch

sorry if I'm explaining it as if you dont know what a motorcycle is but I'd rather explain it too much than not enough - the short answer to your question mtread is - yes ,the switch not the plate
