Presentation: The critical tightness of admission

The Valve box seal of 0.5 mm is located between the motor housing and the flap box. In a 2-time competition engine such as TM KZ10C or the R Series, any leak at this level (air intake) can cause an air / gasoline mixture, causing erratic performance or, in the worst case, a motor tightening.

• Standard thickness: The thickness of 0.5 mm Provides excellent compression capacity to compensate for any microcreme imperfections of the seal planes.

• High quality material: Designed with hydrocarbon resistant joint paper (petrol, additives) and constant vibrations of admission.

• Extended compatibility: This seal is the standard for modern KZ engines from TMKART.

- Installation and recommendations

1. Perfect cleaning: Before laying, make sure the seal plans on the housing and the valve box are perfectly clean and free of residues from the old joint.

2. Dry assembly: This seal is designed to be mounted dry. The use of joint paste is not recommended because it could overflow inside the box and disrupt the gas flow or the movement of the flaps.

3. Tightening control: Tighten the flavor box screws in progressively and uniform manner to prevent deformation or pinch the joint.

💡 Michel's trick

"An air intake to the flap box is often difficult to diagnose because it makes the idle unstable carburation. The trick: When mounting, check that the seal is aligned with the transfer ducts. My Pro Council: The 0.5 mm seal is ideal for housings that already have some seasons. If you notice that your engine takes time to go down on diet after an acceleration, look no further: Change this seal immediately! "

❓ FAQ SEO (Frequently Asked Questions)

Q: Is this seal compatible with TM R1 and R2 engines?

A: Yes, the configuration of the base of the valve box remains identical between the KZ10C, R1, R2 and R3 models.

Q: How often does this seal be replaced?

A: It is advisable to replace it at each disassembly of the lamella inspection check box, or during a complete engine revision. An already compressed seal loses its sealing properties if it is reused.

Q: Are there other thicknesses?

A: Yes, there are sometimes variants in 0.3 mm, but the 0.5 mm is the most versatile to ensure reliable sealing in all circumstances.
