I broke the throttle tube slider on my Tomos.
My mistake was in replacing the whole throttle cable along with the slider.
Now the cable seems too long. It also will not tighten up where it meets the throttle grip in that adjustment piece. It just keeps moving around and the metal adjuster won't stay in the hole in the throttle grip.
It works but there is so much play that when I turn the throttle all the way and then release it, the cable pops out of it's adjustment screw and the adjustment screw pops out too!
It needs the magic touch
