26°C — 25°C+
2026 Rotax
GR8DI / GR9DI
Colder plug for hot conditions / sustained full-throttle running.
Higher NGK number = colder plug (a 9 dissipates heat faster than an 8). Always confirm with a plug check after running.

Save as many carb setups as you like, name them, then tap Set as active to switch. Richer protects the engine; leaner gives more power but risks damage.

💡 AIR SCREW ADVICE
Tight circuit with hairpins — set air screw to ½ turn out from lightly seated. Richens the low-speed mixture for sharper throttle response out of slow corners. Do not overtighten — seat lightly by hand only.
