Copper cylinder head gasket KZ-R2 0.05

Summary: The accuracy of "fine-tuning"

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.

- Why choose the thickness 0.05 mm?

1. Precision setting: Ideal for getting off your squish to the limit value allowed or recommended (often around $ 0,90 $ at $ 0,95 $ mm in kz) without changing dome.

2. Thermal conductivity: Copper allows optimal heat transfer to avoid hot spots on the top of the cylinder.

3. Metal / metal sealing: Under the pressure of the tightening, the copper is slightly deformed to perfectly marry the surfaces, ensuring perfect sealing with combustion pressures.

4. Standard competition: Essential part in the toolbox of any TM Racing engine trainer.

- Michel's trick

"The joint of 0.05 is goldsmith! My Pro Council: Handle it with extreme precaution because at this thickness, it folds like a sheet of paper. A simple brand or a folder and it will never be waterproof again. Small trick at editing: Make sure the cylinder and cylinder head seal plans are 'mirror'. Do not use a joint paste, copper must work alone. And above all, after mounted your seal, always make a measure of squish with tin to be sure that your piston does not come to kiss the cylinder head up to high speed! "

- Mounting & Volume Guide

• Preparation: Clean the solvent surfaces (brake cleaner) to eliminate any oil residue.

• Measure: This seal is often used in addition to other thicknesses (0.10 / 0.20) to obtain the exact rating desired.

• Control: A squish too weak increases performance but drastically reduces the life of the piston cage and rod head bearing.

- Technical specifications

• Material: Pure copper.

• Thickness: 0.05 mm.
