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.
