Removing of the large air box is easily done. Replace the air box with cone filter’s. Re-touring thé breather hoses is simple. On mine I just ran the breather hoses into a inline filter & using a T fitting to run into the throttle bodies. Easy peasy
 Removing the stepper motor mechanically but not electronically. It must stay connected just not the breather tubing. Either plug off or using vacuum or fuel line hose to loop two of the three nipples together & just plug the last one.  
It’s all simple. An engineer in Australia had done the same after reading one of my posts. His GRiSO is a 8Valve mine is a 4 but revs so quick.

The only thing you’ll need to figure out is placement of the battery. I went with a Shorai lithium battery. Ultra light & can be placed upside down on inner part of the rear fender.

I'd advise strongly against it but it's your bike....

What is the aim of doing such a modification and why it is not recommended ?

Fuck nose what the aim is?

The result will be poorer performance and accelerated wear. That is why it isn't recommended.

As for being suggested by an 'Engineer'? I know of at least one 'Engineer' who tried to run a modern Guzzi service agency here. He spent hours wasting my time asking me how to solve problems of his own making. Thing is he was a Civil Engineer. Probably could design a killer multi storey car park but he understood exactly fuck-all about motorbikes. He doesn't bother me any more and he is no longer a service agent.

All it does is increase induction roar, thus making you believe it's making more power and revving more quickly. It isn't.

Aftermarket filters (cone, pod, or otherwise) a little more than rock strainers, thus advancing throttle body wear.

The 5AM has no way of compensating for the increase in air flow, so unless you remap you're just creating a lean condition. Furthermore, the intake temperature sensor must remain connected to prevent a service warning. However, it's now no longer measuring intake temperature..just ambient, or whatever it's tied to. That in itself creates a mapping issue.

I strongly advise against this modification.

Shorai batteries I have found to be quite weak around the terminals and have been known to break off - not a good outcome from that...

Wanna bet? A friend who has been a Guzzi Tech for decades, made the statement that he never heard a Guzzi rev so quick without modifying the the pressure plate with the clutch. Whether it makes more power, I could care less until I do a flash on the écu then it will.
What happens to an engine when you open up the breathing of the crankcase? Any clue?

I would think the rate of revving while settling still has nothing to do with rideability and torque. But heck, I'm just old hot rodder, what would I know.

As am I. At 63 I have been around engines all my life since I was young when I had to rebuild my own Honda 50 engine & my first Briggs engine in the 60’s. Plus became an engine specialist in the 70’s. Went to the Corps after the Marines went to work with a Indy car team owned & operated by Jerry Karl. Here is a question for you, let’s see if you know. How often must Desmo valves on a Ducati be done, shimmed when ridden within legal means? Any clue?
I never mentioned that it increase torque or reliability. The engine just breaths the way they are suppose to.

Anyone who says "I've been doing this for X years" or "I'm a trained blah blah", or "I've been building engines since.." or "I worked in a race team" loses all credibility immediately. We don't care what you think you know, because you are simply wrong about Guzzi's. And don't ask a question about Ducati's. Who cares?

Whatever you think. My credibility is intact. You stated that you were an old hot rod set. Do you know what a hot rod is
Sorry you seem to be a shallow person.

Well, you can't even follow who said what. I never mentioned hot rods.

You have zero credibility with me, and no matter what you claim or whom you insult, I'll always be smarter than you.



Bye!

The preferred air filter mod. I believe it's the lightening of the flywheel that increases revs, not the pressure plate or clutch.

You started it.
It seems as if you have zero knowledge. At least I do & not afraid to do things on my machines.

Sadly the laws of physics can't be altered and are immutable. But you do you.

Actually that isn't entirely true. If you were to ride your GRiSO close to the event horizon of a black hole they might become a bit plastic but seeing as the likelihood of that is slim I think my assessment stands.......

And next you'll be telling us you get 100 HP at the rear wheel!

Pah-no popcorn emoji. Still fun to read shite by no-nothings though. And I don't know much.
