This is my second year owning a 1982 honda urban express nu50, lately the throttle started not returning to the original position, meaning i would have to throttle down manually turning my hand forwards. but now when ridding it will get stuck on full throttle and ill have to shut it off pull over and pull the cable control lever back to close, i was wondering if it was the throttle cable or the handle assemble itself. by the way the other end of the cable(cable control lever) the spring works fine.
