I have just installed a new upper throttle cable and a new throttle grip in hopes of solving my sticky throttle situation, it never worked. No matter where I open the throttle to, it will not return. It works good as a cruise control, but can be very dangerous during sudden stops. The tighter i make the cables the harder it is to throttle. I have loosened them as much as i can at the top by the ignition box on the bar it is easier but still will not return. I know the lower cable controls the deacceleration but it is fine. Anything I am missing? is the spring return that controls the carb slides shot?
