MG V7 Intake hose crunch

[restlicht]

Hi,

my nearly new V7 stone (2022) makes as strange crunch on the right side of the intake hose. I have made a video on it


Is this a normal behavior? What should I do.
It was already at the dealer. They reseted the engine. But this behavior still occurs. The hotter it gets, the stronger the crunch.

I hope you can help me.

Thank you.
Stefan

So the intake track has low air pressure when you open the throttle. That is what should be. Since it is below atmospheric pressure, the track is collapsed a little. Nothing to worry about.

Thank you for the fast reply. Is it normal that it only occurs on the right side? This is what also bothers me.

Left side may do it also. If the intake track is shorter it will be less likely to flex. Don't worry about it, just ride it.

Hello final update.

After taking the bike to the national importer they said that it's not supposed to happen.
So they ordered a new tube. After nearly one month.of waiting they replaced it and it's now working again as supposed to.

The exact same thing started happening with my V7 after 3000kays. I guess the good news is that it is an air-tight seal but I have never seen anything before like this happen on an engine.

Sad to hear that. They (importer) told me it was possibly due to a production mistake of the pipe. Only replacing it could solve it. Glad it was under warranty.

1st I've seen this, must be a bad mold in the process or bad rubber mix.

 

[restlicht]

Yes. That's what they taught of too.
They also said I was the first one they ever had with such a problem.

I’ve never seen that before either. Obviously there is a defect in manufacturing material.

Is anybody making aftermarket intakes for the V7? Maybe I should just swap it out for a better part

No, not likely ever. That said, we *might* be making one for our friend Roland on his 850 LM project linked below;

2022 V7 LeMans 850i - building it -

I’m going to post pics here how my bike is evolving... As this project is already for quite a few weeks at Todd’s shop for his R&D I want to thank him and his team for their graciousness and professionalism ! The best place to bring your bike to!!!!
