How to Deal with Handling Problems
There is usually never one adjustment that will cor-
rect a certain handling quirk. You will usually end
up with several changes in setup to achieve the
same goal. There are certain basics to keep in
mind, however, when you are working with your
sled:
– Handling problems encountered when entering
a corner are usually corrected by working with
front end adjustments.
– Handling problems encountered when exiting a
corner are usually corrected by working with
rear suspension adjustments.
– Basic handling problems are often traced to im-
proper suspension adjustments.
Guide to Handling Problems
NOTE:
PUSHING refers to the front of a vehicle
not steering as much as the driver wants. The skis
are not grabbing the surface with sufficient force.
LOOSE refers to the rear of a vehicle sliding out-
ward in a turn. The track is not grabbing the sur-
face with sufficient force.
NOTE:
Center spring/shock refers to the front arm
of the rear suspension.
1. Problems encountered when entering a corner.
a. Front end pushes coming into a corner (steer-
ing is not precise).
– Sharpen carbide runners.
– Add more carbide.
– Shorten limiter strap on center arm.
– Increase negative camber of ski legs.
– Increase ski spring preload.
– Decrease center spring preload.
b. Rear of machine starts to come around or is
loose when entering a corner.
– Lengthen limiter strap on center arm.
– Decrease ski spring preload.
– Decrease negative camber of ski legs.
– Increase center spring preload.
– Sharpen/add track studs.
c. Inside ski lifts.
– Reduce the amount of negative camber on
the ski legs.
– Check for free operation of stabilizer bar.
– Decrease preload of ski springs.
– Shorten limiter strap on center arm.
2. Problems encountered while going around or
exiting a corner.
a. Front end pushes coming out of corner (steer-
ing is not precise).
– Shorten limiter strap on center arm.
– Decrease center spring preload.
– Check condition of carbides.
– Add more carbide.
– Increase negative camber of ski legs.
– Increase ski spring preload.
– Increase rear spring preload.
– Tighten A.C.M.
– Increase rear to front coupling.
b. Rear of machine starts to come around or is
loose when exiting a corner.
– Lengthen limiter strap on center arm.
– Decrease ski spring preload.
– Increase center spring preload.
– Decrease negative camber of ski legs.
– Decrease rear spring preload.
– Loosen A.C.M.
– Decrease rear to front coupling.
c. Left ski lifts.
– Shorten limiter strap on center arm.
– Decrease center spring preload.
– Check for free operation of stabilizer bar.
– Increase stabilizer bar diameter or shorten
end levers.
3. General handling problems.
a. Machine darts from side to side on straight-
away.
– Check ski toe-out.
– Check for loose ball joints in steering.
– Too much negative ski leg camber.
b. Excess effort required to turn handlebars.
– Check steering linkages for binding and/or
corrosion.
– Rubber blocks between skis and ski legs
have too much preload at the rear (causing
rear of skis to be pushed down too much).
– Lengthen limiter strap on center arm.
– Increase center spring preload.
– Decrease ski spring preload.
– Too much carbide on ski runners.
4. Adjusting the suspension for ride and comfort.
