I have no clue about atvs but I just had to replace my slide on my yz 125! The throttle cable comes down and there is a spring between the carb top and the slide. At the bottom of the spring there is a little screw that screws into the slide. The little screw is attached to the cable. So you just take the cap off an the spring should come out than you just put a new spring in and put it back together
