Note: TKR1222 and TKR1226 Shims - The gear mesh should be tight without any binding. TKR1226 should

always be installed. Then test 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. You may end up using only one shim on the gear side.

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 landing jumps on throttle.
