if the throttle sticks it can be 1 of 3 things, the cable is getting hung up so buy a new thorttle cable instead of just fixing the old one (who knows how long it would alst from how old it is, better safe than sorry!), i dont know what kinda carb is on that bike but the ball slide or flat slide is sticking so you could easily take apart the carb and take a look at it, or it could be the floats sticking, again taking the carb apart and checkin them out can easily fix this problem. i would take the head apart and check out the cylinder and if it isnt scored throw a new piston in thier for safe measures, if your thinking the clutch doesnt have much life left, trust me buy some new plates and maybe heavy duty springs if you have the extra 10 bucks, check the chain and sprockets for wearing, most of the bearings are probably shot on that bike so they would have to be replaced, and decent tires will have to be replaced soon also....its a project but can easily become the bike you end up riding if your atv is down for repairs or maintence or something

maybe i went a little over-board with it but those are the things ive learned to pay attention to with bikes
