The Four-hole exhaust seal Provides the critical link between the cylinder exhaust light and the flange (or the collector). On a 2-time competition engine like the Tmkart, the slightest leak at this level disrupts the return wave of the exhaust jar, resulting in an immediate loss of torque and the callamine projections on the bottom of the motor.

The 0.30 mm base gasket is an important thickness in the adjustment range Tmkart. By raising the three tenths cylinder, you move the opening times of your transfers and your exhaust light up.

This is the privileged setting for fast circuits with long straight lines because it allows the engine to "better breathe" in the towers. This seal is perfectly compatible with the entire line of gear motors: KZ10B, R1, R2 and the new R3

The Copper cylinder head gasket 0.20 mm is the thickness "comfort" and safety for engines Tmkart kz-r2. In the quest for performance, this seal is used by drivers and mechanics to increase the height of squish (Space between the piston and the cylinder head) to make the engine more flexible or to compensate for a new "high" piston.

Copper is preferred in competition because it ensures a Exceptional thermal dissipation, transferring the calories from the combustion chamber to the cooling circuit with efficiency much greater than the conventional joints.

The Copper cylinder head gasket 0.05 mm is the finest thickness available for engines TM KZ-R2. In a competition motor as the KZ, every hundredth of a millimeter count. This seal makes it possible to adjust with surgical precision your squish (Height between the piston and the cylinder head at the high-standing point) to optimize the combustion without risking the detonation.

The choice of copper guarantees excellent thermal conductivity between the cylinder and the cylinder head dome, thus promoting a homogeneous cooling.
