Properly Adjusting the Slipper Clutch

Adjusting the slipper clutch is crucial to performance and reduced drive train failure. If the slipper clutch is set too tight, you stand a greater risk of tearing up spur, differential, and plastic idler gears. If the slipper is set too loose, you are going to lose most of your power to the clutch during acceleration and you stand a chance of heating the slipper pegs up to a point where you can melt the inside of the spur gear. As you can guess there's a fairly fine line between the two. Hopefully this will help you understand how to properly adjust it.

The first thing you need to do is to tighten the slipper clutch down all the way. If you have the gear cover removed you will need to hold the spur gear with your other hand to do this. If the gear cover is installed and you are adjusting the slipper through the rubber grommet hole, you'll want to prevent the tires from turning while tightening. After you have tightened the slipper down, loosen the nut 1/4 turn to 1/2 of a turn. The 1/4 turn range between 1/4 and 1/2 of a turn is where you want to stay with your adjustment. Closer to the 1/4 mark gives you less slippage, while closer to the 1/2 mark gives you more slippage.

Here where you adjustment range should fall between.
