This clutch does not come with or use set screws. Clutch does not need set screws as long as the end of the crankshaft is threaded for a bolt. Most go kart clutches are held onto the shaft with a bolt and larger washer. Extra washers can be used on the crankshaft to space clutch.
**There are many variables that play into the performance of a clutch. Tire size, rear sprocket size and rear drive set-up are a few of the main variables that could affect clutch performance. If you are using large tires or a small sprocket, your vehicle may require a belt drive system. Clutch performance is not based solely on the engine size.**
