CHECKING ATV SETUP – JET SUSPENSION
.
.
Check Sag– This gives us a good bench mark of spring, shock length and preload for that particular link.
This takes 2 people – Take a tape measure and measure behind the rear tire from the axle to some point straight up on maybe a plastic mounting bolt – WHILE the rider lifts up on the rear grab bar until the rear tires are off the ground (shock is fully extended). The shock must be fully extended!! – remember this measurement.
Now keep the tape measure right there and the rider can let the rear down then stand on the foot pegs while holding the handlebars – this gives a neutral position to measure. The difference between the first measurement and now is the SAG.
SAG = _______________
Ride Height – Make sure tire pressure is correct!
With the rider standing on the pegs NOT SITTING, measure from the ground to the bottom of the frame in 2 places (under foot pegs and under the radiator.
Front = _______________ Rear = ________________
Rear Shock rebound – NEVER bottom the rebound adjuster hard and you never want to run the adjuster all the way hard! (Will Hydro lock shock components)
Are you able to pull the rear tires just off the ground when you push down then pull quickly up on the rear grab bar (without extended the rear shock all the way). The point of this is to have the rear tires fall away from you when you pull up quickly. This is kind of an art, but you do it enough, you’ll get the feel. If so, how far do the rear tires come off the ground (i.e. ½”, 1” or 2”)
Rear Tires off?______________ How far roughly?_________
Where is the rebound adjuster from all the way hard?___________

CHECKING SHOCK LENGTH
Checking shock length – remove all three shocks. Now you want to block the bottom of the frame under foot peg area and under radiator area. Take an shock eye to eye measurement, then you will drop the quad on lower blocks and take an eye to eye measurement – this will give us extension and compression length as well as shock travel and wheel travel (motion ratio).
For TT – Extended length 9.25” Blocks Front __________Rear__________
Compressed length 1” Blocks Front __________Rear__________
For MX – Extended length 12” Blocks Front __________Rear__________
Compressed length 1.5” Blocks Front __________Rear__________
For XC – Extended length 11.75” Blocks Front __________Rear__________
Compressed length 1.5” Blocks Front __________Rear__________
For Desert – Extended length 12.5” Blocks Front __________Rear__________
Compressed length 2” Blocks Front __________Rear__________
HANDLING FEEDBACK:
- Does the rear end buck up or kick up in the rear when you hit something?_____________
- Does the rear squat coming out of the corner and get good traction?_________________
- Does the rear bottom at all? hard?___________________________________________
- Does the front bottom?_____________________________________________________
- Is it overall harsh or plush ride?_______________________________________________
- Does the front roll over on corner entry?________________________________________
- On jumps does the quad fly level?_____________________________________________
