SHOCK FILLING

SHOCK
OIL ➊ Fully extend the piston rod so the piston is at the bottom of the shock body.

➋ Hold the shock upright and slightly overfill the shock body with shock oil.

➌ Let the oil settle and allow air bubbles to rise to the top. Slowly move the piston up and down until
no more air bubbles appear. Add shock oil as necessary.

➍ Pull the piston rod most of the way out of the shock body. Let the shock rest for 5 minutes to allow
the air bubbles to escape.

CUTAWAY VIEW

After you insert the membrane ensure

that it sits properly all around the alu
cup properly.

When installing the shock cap assembly on the shock

body, some oil will leak out... this is normal.

Fully tighten the cap and clean off any excess oil.

After the shock is assembled, the shock rod will push itself
out of the shock body fairly quickly.

Follow the next procedure to adjust the rebound.

After the shock is assembled you have to set the Shock Rebound.

3. After you have set the Rebound Adjustment, re-install the shock lower composite cap.
2. VERY SLOWLY do the following: Fully pull out the shock rod, push it back in fully, and then fully pull
it out once more. Repeat this procedure the following number of times to achieve the desired Shock 4. Check the Shock Rebound setting by pushing the shock rod fully into the shock body, releasing it, and
Rebound setting: observing how far the shock rod extends by itself:
10 times - approximately 75% rebound (high rebound - suggested for very low traction track) * 25% out of the shock body (low rebound)
15 times - approximately 50% rebound (medium rebound - suggested for standard track) * 50% out of the shock body (medium rebound)
20 times - approximately 25% rebound (low rebound - suggested for very high traction track) * 75% out of the shock body (high rebound).
If the shock rod rebounds too much, return to Step 1 and repeat the procedure.
During the Rebound Adjustment procedure shock oil will leak out of the shock body through the O-ring

It is VERY important that all shocks are equal length.
Fully extend the shock absorber and measure the end-to-end

measurement. If a shock absorber is shorter or longer than others,

Do not allow carburetor to close to less than 0.5mm.

Turn on transmitter and receiver and set the throttle servo trim to the neutral
position.

Adjust the idle adjustment screw on the carburetor to open approx. 0.5-1mm.

Adjust both collars on the carb and brake linkages accordingly. The carb

With the engine NOT RUNNING but the receiver turned ON, apply full throttle at
the transmitter.

Adjust the transmitter‘s throttle servo high-end point so that the servo horn fully
opens the carburetor when the transmitter‘s throttle control (e.g., throttle trigger)
is at 95% of full throttle. The servo should not have excessive strain when at full
throttle, or throttle/carb damage will result.

If the transmitter does not have throttle high-end point adjustment, adjust the
throttle linkage pivot position on the servo horn until full throttle is obtained.

Adjust the composite collar on the brake linkage so the brakes work smoothly.

If the brakes apply too much or not enough, adjust the collar accordingly. If your
