Summary: the first link of the power

The Exhaust ball (or pipe) is a foundry room attached directly to the cylinder output. Its role is twofold: it guides the burned gases to the exhaust pot while allowing a slight articulation thanks to the springs. Versions EvoIt is machined with extreme precision to ensure that the gas flow does not meet any restrictions, ensuring a linear rise.

🏎️ Why choose the original ball joint Rotax EVO?

1. Maximum sealing: Its spherical contact surface is perfectly roded to fit the pot collector, avoiding the calamine leaks that dirty the engine and lose compression.

2. Thermal resistance: Made in a high temperature steel alloy that does not deform despite the intense heat of the exhaust gas at the cylinder outlet.

3. Regulatory compliance: Official piece approved for all competitions Rotax Max Challenge (Junior, Senior, Master, DD2).

4. Longevity: Specific surface treatment to limit moisture-due oxidation and combustion residues.

💡 Michel's trick

"The patella is often the source of scrap streams and losses of power! My advice: Each disassembly, check that there is no calamine dried on the spherical part. A very fine emery shot can be used to find a smooth surface. The trick of old briscard: Always put a little copper grease or high temperature grease on the knaping before reassembling the pot. It makes it easier for movement, it improves the sealing and it avoids that the pot does 'eat' the ball with the vibrations! "

🎓 Mounting Guide

• Installation: Fixed on the cylinder using the two specific screws. Make sure the seal between the patella and the cylinder is in good condition.

• Safety: Check the alignment of the lugs for the exhaust springs. The springs must be well stretched to flatte the pot on the ball.

• Interview: If you see black traces (leaks) around the ball is that it is time to clean or check the tension of your springs.
