The reason I cut my little pin off was because as you can see I wanted my brake lever and mirror mount to line up exactly where I wanted it

With that little pin on there I couldn't figure where exactly to drill the hole so I just cut it off
I've got over 40K miles on my Whizzer and I never had the throttle slip because I cut that stupid pin off

Since ya say you don't have a drill
Just snip it off with wire cutters and file it smooth flat
If I guy like me is gonna do it to his Beautiful Whizzer throttle then you'll be fine doing it to your 2 stroke throttle
The throttle won't slip on ya
