Adjusting the Slipper

The slipper is a key component of the drivetrain that is designed to help 

absorb sudden or large impacts that would otherwise stress various drivetrain 

parts. You should never run the LST XXL with the slipper locked (completely 

tight). The slipper can also be used as a tuning aid for extremely slick 

conditions. To adjust the slipper, start by turning the 1/4-inch adjustment 

nut clockwise (tighten) until it gets tight and the spring is compressed. 

Do 

not overtighten

 as you will strip the nut. Now turn the adjustment nut 

counterclockwise (loosen) one full turn. This should be a good overall setting.

2-Speed Adjustment

Although pre-adjusted at the factory, the two-speed can be adjusted to shift 

at the point that suits you best. Under normal circumstances, it should shift 

slightly before the engine reaches maximum power. The actual distance traveled will vary with the gear ratio and 

tune of the engine. There are two adjustment screws (see fig 1) that must be changed evenly for the two-speed 

to function correctly. Turning these clockwise will make it shift later and require the engine to rev higher. Turning 

them counterclockwise will make it shift earlier and require less engine speed. If you should get lost adjusting the 

two-speed, start over at the 

factory setting

 by 

lightly

 bottoming out the adjustment screws and then backing 

them out 

five

 full turns. The procedure for adjusting the two-speed is as follows.

• 

Remove the gear cover.

• 

 Turn the spur gears until the adjustment hole is visible in the bell housing between the large and small spur 

gears.

• 

 Hold the small spur gear and, using your thumb, rotate the slipper forward until you can see the head of one 

of the adjustment screws.

• 

 Use a 5/64 Allen wrench to make your adjustment in 1/2-turn increments. Use the bent leg of the wrench as 

your guide.

• 

Turn the slipper forward 1/2 rotation to adjust the other adjustment screw like the first.

(Remember to always adjust BOTH screws the same amount)

• 

Test drive the model to check the new shift point and 

replace the gear cover

 if satisfied.

• 

Never

 run your model without the gear cover, as it is dangerous and gear damage will occur!

Turning the adjustment screws 

counterclockwise makes the 2-speed 

shift sooner; turning clockwise will 

make it shift later.
