Full description: what is the purpose of this piece?

Without this grip, your engine can not simply eat in essence:

1. Pump engine: On a Rotax, the fuel pump is not electric. It uses pressure and vacuum pulsations created by the piston movement in the low engine. This socket is the channel that transmits this force.

2. Pneumatic sealing: Its precision thread ensures that the air circulates only towards the vacuum hose without pre-compression pressure at the crankcase.

3. Sustainable material: Made of brass or treated steel, it resists constant vibrations of the housing and heat released by the engine block.

4. Secure connection: Its splined tip is designed to provide maximum intake at the hose, avoiding that it unplugs with the jolts on the track.

💡 Michel's trick

"It's the most forgotten room when cleaning motor! If your ratatouille motor or stops, checks this outlet. With the time, calamine or burnt oil can buttach the small central hole. If it's stuffy, your gas pump stops. My advice: Pass a Little blow of blowing in each revision. And above all, check that your hose is tight with a small Rilsan necklace on this socket. An air intake here, and it is the carburation that becomes crazy!"

🎓 Tuto: installation and maintenance

1. Screwing the crankcase: Screw the plug on the engine crankcase. CAUTION, the thread is fine and the crankcase is aluminum: tighten firmly but without forceing like a deaf to do not make the net.

2. The seal: If necessary, use a low wire brake drop or a copper seal (according to version) to ensure that the depression is total.

3. Connection: Thread the vacuum hose (often black or transparent luxury hose) to the bottom of the tip.

4. Operating test: If you have a doubt, unplug the pump side hose and launch the engine (or turn the wheels in jack): you must feel small air pulses out of the outlet.

✅ Compatibility

• Rotax 125 Max, Evo, Junior, Mini, Micro

• Rotax 125 DD2

• All gasoline pumps for depression (Mikuni, Dell'Orto)

Note Magickart: Original room Rotax. A clean and well-fixed depression is the guarantee of a constant gasoline, even at high speed.
