Just wondering about how others mount their throttles onto the handlebars.
Do you drill the hole into the handlebar for the pin to go into, or do you grind away the pin and mount it relying on the clamping force of the throttle clamp?
I always drill the hole. It assures me the throttle won't turn if I didn't get the screws super tight. Most of my kits had a metal pin, but some have plastic. Either way, I like to make use of the pin. Just have to make sure it's where you want it before drilling.
I've always drilled. It in no way compromises the strength of the handlebars and assures that the twist grip stays put. Relying on the plastic and clamping action is not the best idea. It will eventually loosen.
I've heard of people wrapping the bar with tape, sandpaper and even, heaven forbid, using JB Weld to keep the twist grip in place.
Drill the bar.

I ground most of the post down leaving a little nubbin sticking out. When I tightened the screws it digs into the aluminum and doesn't turn. I did that because I'm one of the one's that didn't get a instruction manual.
i have used jb for so many thing i love the stuff,know a guy that fixed a cracked block on an old farmall tractor worked great, i once rebuilt a rusted out float bowl on a minneapolis-moline tractor, no problems.
