Max,
Here are the pictures of the airbox cover on my 2006 Morini. I think that the air cover on the Piaggios should be the same so let me know if it is not the case.
If it is different, do you think I should remove it?
(Edit my pics and repost if you need to show anything)

Muchacho — you can remove that tube and get a little bit more air into the engine. Not a lot more I'm sure, but a bit more. And the engine will sound a little different too.
Whatever restriction Benzia is talking about sounds like it would be somewhere between the air-box and the crankcase...
@ muchacho : If you are running unrestricted ECU take this part out >
Its not all about 'more air' but also about the lenght of the air intake .....

Could you explain why, The Max?
-I think puls working in the inlet and the A/F factor are reson for thisOriginally Posted by Ciudale
In car world o.a. porsche and BMW usses a adjusteble inlet lenght is . In the Porsche a trothel ,will swiths from a long lenght inlet,to short lenght,depending on rpm's
For peopel want to test this :
-Do a run with the airbox open ,or take it off .....

Hey Max,
Please keep in mind that I had absolutely no experience in this, I just require a logical (or technically detailed) answer.
First
Do the Piaggio 06s have the tube that my Morini 06 has?
Second
I have tried running without the airbox cover and there is a difference.
However, trimming the tube down as you suggested only does not increase the ammount of air getting to the engine because the opening is still the same size.
Third
Does increasing the amount of air supplied lean out your mixture? How does it affect a stock engine with a pipe?
I think they do,but as I look to your pica of the box it seems to me its a differend model airbox is used
Idd the openings stayes the same,but there is a resistance factor from the surface. Long lenght is long surface ,and the more surface there is the more airspeed slows down
but as I said : Its not (only) about more air,but (also) about lenght (puls working) You tested without the box cover. I hope you don't let mislead you about the noise.
You noticed differends....is it correct to say ,that the differnds you noticed,not in all rpm zones was positve ? So its a 'win and loss a bit' thing ?
I dont think so,because more air leads to higher case pressure. And high case pressure leads to more feul because the compressor system
I do not know,but stock pipe hold lower puls working,so needs other lenght of inlet as performance pipe
And the higher rpm the engine runs ,the shorter lenght of inlet it can handel

Did u have to cut the pipe to get it off?
I have a de restricted ECU with stock exhaust should I take it off to get better performance?
I think you have a 2006SR50 with a Piaggio engine right?
Have you checked to see if the tube is in your airbox too?
I have the 2005 sr50 r factory piaggio engine.
yes its got the pipe in but I think I would have to cut the pipe to get it out
I would wait cutting up the pipe until Max gives you an answer. When I originally asked him we were talking about SR50s with Morini engines. I am not sure if this affects Piaggios.
Muchacho and finn
do you realy need to CUT the pipe ??
In my case (01-03 morini) you just take it out
>>>>CLICK FOR DIAGNOSTIC TOOL<<<<
i think it has 2 be cut but maybe i i just missed some thing when i looked
I have cut part of the pipe off and the acceleration seam better and the top speed seams the same.
This came up awhile back, I don't know if anyone has tried it.
