Devise a way to attach a small ball bearing pulley with a bracket that the twistgrip cable would attach to above the pulley.
Then bring the carb cable from below, around and over the pulley, with the end attached to something solid and unmoving.
Now, when the upper cable is pulled, the free end of the lower cable will travel twice the distance that the upper cable moved.
I've done the same thing but reversed, to the brakes on an ultralight to give more power to the brake arm for stronger brakes.
thats what i was originally was thinkin of doing but im very happy with the yz throttle. it had a large mukini slide carb. so it did just what i was wanting it to do. il have a build thread soon when i finish the bike.
