Air filter box (bits you take off)

[hihhs]

I've got an M1100 and a bad case of the mod bug, coupled with limited knowledge and limited funds. It is terrifying combination!
I've done the bolt on thing with the Tergmi slip-ons, rizoma grips and bar ends, CW tail chop, CRG mirrors, & added a "hidden" garage door opener.

I'm trying to lose as much useless plastic as I can. I've taken out the charcoal canister &  ordered some materials to get rid of all the plastic around the oil cooler.

But what I'd really like to dump is that ridiculously big air filter box (in rectangle in picture)
And what the hell is the thing in the circle?
I know I'd have to fab something to hold the air filter(s) and that the ECU and coil mount to the air box, but I could fab something a bit more minimalist  to mount those.


So how much trouble how am I thinking of bringing on myself?

A couple of pod filters would be good for replacing the airbox and as you have stated you would need to fab some kind of bracket to hold all of the left over loose bits.

As for the thing in the red circle, I am pretty sure that is the flux capacitor.

If not the flux capacitor then it might be a stepper motor that is connected to the throttle bodies for some purpose that I am not quite sure of.

[hihhs]

I always thought flux capacitors where bigger 

Do ya' think removing it would alter the airflow to the point I would need the ECU tuned (like Duc mechanic with DDS involved)?

[kopfjäger]

If you go with pods, you are more than likely gonna need to get it tuned.

If you follow the schematic, it looks like the thing in the circle is the catch-box for the crank-case breather.

Wow, that is one restrictive airbox for an 1100. Especially compared to the 1000DS motors in the S2R's...

I thought that at first but then I looked at the OEM parts catalogue over on Ducati Omaha's site. The little part inside the red circle was labeled "stepper motor". One of the hoses from it goes to the airbox, while there are two other hoses (not shown) that go to one of each of the throttle bodies.

I redact my catch-box theory.  Flux capacitor it is! 
(stepper motor probably allows variable amount of air into TBs for cold idle and/or mixture adjustments for EPA)

Look at the big brain on Brad (Ryan)...

Thanks for all the replies

It sounds like removing the air filter box would be a GIANT PIA

I think I could get around everything except the stupid stepper motor and the need for a mechanic. There is no Ducati mechanic locally.

Anybody got any suggestions on how to accomplish this?

Just start pulling shit off.  Start her up.  Drive her around a bit.  If she runs... that shit wasn't necessary in the first place.  If she don't... then put that shit back on and start pulling shit off from another direction.  Worked for this "shade-tree hack".  I've got a whole pile of shit that I took off of my bike just sitting on a shelf in the garage.  Some folks might look at a piece or two and say "Hey man... that's a pretty important piece of shit that you took off there."  I say "If it were that important, then why is she still running without it?"  As for the stepper motor... try removing it and capping the place where the tubes run into the throttle-bodies.  <The stainless, metric, allen-head bolt section at ACE Hardware is your friend.>  If that don't work just replace tube #18 with a little breather-filter and call it a day.  Replace tube #2 with another breather-filter off of the crank-case.  Then just rip the whole make the beast with two backsing air-box out and stick some pod filters right on to the throttle bodies.  She'll run well enough to get you somewhere they can adjust the fuel trim if necessary.

removing the air box will change the amount of fueling you need. you will need to wait til the PC V or even a 2Bros Juice box is available for the 1100.

and that stepper motor is curious, seems to be connected like a crankcase breather but to the throttle bodies. ... wait, you dont have the manual cold start do you? I bet it for cold starts. you might have to keep it in place, but put a small airfilter on it. like the crankcase breather as well.

I really like the way you are thinking right up to the end. I live in Hawaii and there is no Ducati mechanic on this island. I have to crate the bike and ship it to another island or convince the dealer to let me pay to fly the mechanic here, & pay the usual hourly rate for every minute he is gone from work. OUCH!

Thanks for the reply.
Nope, no manual cold start. I've heard of the 2bros things and checked out their site. They've got the Juice Box for the 696 already, so the 1100 shouldn't be too far behind. BUT those little rascals are pricey. I'm trying to operate on a budget at this point.

No, PC V refers to Power Commander V (as in 5). it's another computer to adjust fueling. it's more expensive than the Juice Box. The Juice box is the most economical box to adjust your fueling. SO, unless you can remap your computer, which I don't think anyone has taken on the new Siemens yet, you will have to junk the idea of junking your airbox until you can get one of the systems.

Basically why you need this...
You're going to give the bike a ton more air leading to a lean condition. which will make the bike run hot and probably like shit.
So, you have to adjust the fueling to add more fuel. well since it's fuel injected you have to either change the amount of fuel the computer is sending (a remap or the Ducati Performance replacement) or intercept the signal and add more fuel (PC V or JB or the like) BUT if you intercept the signal you will also have to intercept the signal from the exhaust sensors that tell the computer... hey you have too much fuel... the PC V, JB and the like do that as well. I think the Ducati Performance total ignores it. (EDIT: though after reading that... it doesn't make sense since the computer will be reading a lean condition and should correct for it... PLEASE smarter people chime in)

AND this goes along with ...
If you change out the exhausts and air boxes.. add the computer.... you may get about a 7 to 10% HP increase... 2Bros is claiming 7lbs loss, 7lbft torque and 7hp for the 696. so on the 1100 you are figuring more than 100HP
