Note: TKR1222 - The gear mesh should be as close as possible without any binding. Test the tment of the di

with both TKR1222 shims on the gear-side of the di. If the di turns freely without binding, continue to next

step. If the di binds and does not turn freely (it will make a grinding or crunching sound when spun), remove

one TKR1222 shim from the gear side and install it onto the other side of the di. Reassemble and test the mesh

again. If it is still binding, remove the second TKR1222 shim from the gear side and install it onto the other side

of the di. When you are satised that you have the best gear mesh possible continue to the next step.

Note: The front and rear of

the car use dierent inner

bulkheads.

The front is angled

whereas the rear is oset

Changes to the wheelbase have a dramatic eect on handling,

since it shifts the disribution of weight over the rear wheels.

This adjusts traction. By shortening the wheelbase at the rear, you

are placing more weight over the rear wheels.

Changes to the wheelbase also change the amount of sweep the

rear driveshaft will have. More driveshaft sweep creates an eect

similar to anti-squat, where the rear end gets pushed upwards on

throttle. This helps reduce chassis slap when landing jumps on throttle.

Note: The steering stops provide adjustable

travel limiters that you can adjust to your

driving style. For very tight tracks you may

want to experiment with less limiting washers

(more steering travel). However, with too

much steering travel the rear end can lose

traction more easily coming out of corners.

After months of testing on dierent track

surfaces, 1 washer is the best starting point.

Shock Filling Instructions

For both front and rear shocks

The following steps and information will provide you with the best way to ll and bleed your

shocks. After thorough testing, we've found it's easiest to complete steps 1 through 3 on each

shock before moving onto step 4. By the time you've nished step 3 on the last shock the rst

one will be ready for step 4.

Standard or Vented Cap Build:

Step 1: Extend the shock shaft all the way down. Fill the shock with oil until the it is about 90% full.

Step 2: Slowly pump the shock shaft up and down 3-5 times to release air bubbles from underneath

the piston.

Step 3: Let the shock rest vertically with the shock shaft fully extended for ve minutes or until all

the air bubbles have released.

Step 4: Next you will top o the shock with oil, to about 1-2mm below the top edge.

(If you do overll the shock, it won’t hurt performance, it will just spill out and make a little bit of a

mess. If you underll the shock, it will cause air to be trapped inside.)

Step 5: Place the bladder INSIDE the shock cap and put a few drops of oil on the bladder.

Step 6: Put a paper towel down below the build to catch drips and have another ready to

wipe o excess oil. Place the cap on the shock and screw down about half way. Lay the shock

over about 45 degrees with the bleeder hole facing up.

Step 6A: (Standard non-vented “Stock”) Push the shaft in for the amount of rebound desired.

Step 6B: (Vented) Push the shaft in until about 15mm of shaft is showing.

tMake sure that you match the rebound amount between the left and right shocks.

tOil should be oozing out of the bleeder hole.

Step 7: Hold the cap rmly in place with the bleeder hole facing up and turn the shock body until

hand tight. The shock will continue to ooze oil.

Step 8: Fully tighten down each shock with shock tools until cap is secure and wipe excess oil away.

Emulsion Build:

Prep your shock caps TKR6018 (optional for NT48) accordingly by drilling out the large angled

bleeder hole in the top of the cap. Place the larger thin o-ring around the base of the threads

where the shock cap screws on (see diagram on the next page). This seal is crucial to the build.

Follow steps 1-4 above.

Step 5: Rebound is more of a natural side eect of an emulsion shock. It’s not something that can

be set accurately because you run the risk of hydrolocking the shock if you do not push the shaft

all the way in when you bleed it. For now leave the shaft fully extended.

Step 6: Fill the shock up, over lling just slightly without spilling to create a small dome of oil.

Step 7: Place a little bit of oil in the shock cap and quickly put the shock cap on the shock body.

Tighten the cap all the way down. Very slowly push the shaft in. Oil will start to bleed out of the top

of the cap. While wiping away excess oil, continue to slowly push the shaft in ALL THE WAY.

If no oil comes out when the shaft is fully inserted, you will need to start over at step 6.

Step 8: Install the TKR1341 M4x6mm at head screw and TKR5125 black o-ring to seal

the cap (see diagram). Tighten until o-ring is fully seated.
