The TMKART rubber flange is more than just a fitting. Designed specifically for the most powerful KZ motorizations (KZ10C, R1, R2 and the new R3), it ensures the junction between the carburetor (usually dell'orto VHSH 30) and the flap box.

Its technical elastomer structure is formulated to provide sufficient rigidity in order to maintain the carburettor perfectly aligned, while maintaining a flexibility capable of absorbing high frequency vibrations. This avoids the fuel emulsion in the tank, ensuring stable carburation, even more than 15,000 rpm.

- Why choose the original tmkart flange?

1. Anti-vibration design: Specific material that reduces internal turbulence and protects the carburettor from mechanical shocks.

2. Total sealing: Avoid air intakes, often responsible for erratic engine behaviors or breaks by too poor mix.

3. Hydrocarbon resistance: Does not harden and swell to the repeated contact of gasoline and competition oils.

4. Perfect fit: Diameter and internal alignment optimized for the original TM valve boxes KZ10C models to R3.

💡 Michel's trick

"The admission flange is your peaceful insurance! My Pro Council: Monitors the slightest to fold slightly rubber by hand. The trick: When mounting the clamp, do not hug like crazy! If you crush too much rubber, you will end up shearing against the carburetor edge. Warning: If your engine begins to have an unstable idle that goes down again, it is often a micro-crack in this flange. Spray a little brake cleaner on when the engine runs: if the speed changes, it's that it's split! "
