I can't find the pics, but what I did was just took my throttle tube of my bike. Then took a bigger sized zip tie and cut it to length to wrap around the tube where the cables touch. And super glued the zip tie to the tube. Which makes the tube bigger. Works great too I can deff tell a difference. As to how much I used to turn the throttle to now.
It's a cheap, quick way to shorten the throttle turn.
I also used a lil needle file to make a small grove in the zip tie where the cable begins to touch it. I didn't want to hurt the cable.
I'd recommend doing it if you're bored have a Zip Tie and want a shorter turn.
