Ducati Monster Forum

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.

I always thought flux capacitors where bigger  [cheeky]

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

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 [thumbsup]

It sounds like removing the air filter box would be a GIANT PIA(http://www.picpiggy.com/smile/sad/sad0049.gif) (http://www.picpiggy.com)(http://www.picpiggy.com/smile/sad/sad0049.gif) (http://www.picpiggy.com)(http://www.picpiggy.com/smile/sad/sad0049.gif) (http://www.picpiggy.com)

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

+1 I can personally vouch for the wheeling popping 620 that this method has worked for.

Power Commander's website shows the PC V is "coming soon" and will retail for $360. That kind of money to get rid of a piece of plastic is a little much. BUT $360 to get rid of an ugly POS and INCREASE HORSEPOWER? That is a damn bargain. It would be foolish of me NOT to buy into a deal like that, don't you agree?

So it looks like a bit of waiting game now.

But I gotta admit that the "shade tree-rip shit off" has a certain appeal if only I had access to a mechanic that could unf^*& anything I f^&*ed.

to be honest. i'm gonna go the 2Bros JB way with a K&N filter. i ride in the rain too much to go pod filters. I have aftermarket exhausts. so i'm hoping for a 10% gain. and i won't need a mechanic with a dyno to help set up the PC V.

My exhausts cost around 500 dollars, the JB will be another 300 dollars and the filters run between 50-70 dollars. so for less than 900 i think i can get a 10% increase in HP and Torque. <100 dollars a percentage point... ... now after rereading that.. the Stainless Steel Termi system for 1000 with the Ducati Performance computer sounds like a deal ... oh and the Ducati Performance ECU gives you a higher redline!

I just installed the TB juice box on my 696 since the pcv will never be released it seems like... It's a very easy unit to use and I noticed immediate differences with it... Smoothed out acceleration and made that <4k rpm surging and uneven throttle disappear... I have new slip ons without the baffles and a high flow air filter so my bike was running leaner than stock... I recommend it as a easy and quick fix... Plus it's cheaper

FWIW the stepper motor is how the ecu adjusts your idle.  I removed mine from my s4rs.  You need to be prepared to adjust your idle air bleeds and cold idle warm-up speed if you remove it.

Well that doesn't sound like fun.
Thanks for the info.

I've already got the termi's and the performance ECU. Do you think that would cause a problem with the Juice Box?

THAT would have been good information to start with.

You have a free flow intake that came with the kit as well.

I think if you take off the air box and go pod filters you may have to use a fueler, but you are already running less lean or even rich using the DP ECU so the route of take things off til it stops running great may work for you.

You are right. At the very beginning of this thread I wrote that I had the termis but I didn't include the the ECU. MY BAD!

I installed the termi slip-ons and ECU just prior to my 600 mile service. The bike ran fine but I could smell that it was running rich. The ducati mechanic came over, did the 600 mile service and tuned it. It runs fine but still smells rich.

The  termi kit did come with an air filter and the vented cap that replaces the stock cap & those were installed also.

What do you mean by "fueler"?

the 2bros JB is a fueler. it really does nothing else but intercept the signal to the fuel injectors and adds more fuel.

i see what you are trying to do by taking the plastic out. but aesthetics vs performance... i would keep the system the way it is. there are other places to pull things off.

I think you are right. It seems like I would be opening a big can-o-worms.
Bummer though. It would look much better with the open frame in front.

If it smells rich, then it could use a little more air.  Maybe not a full removal of the airbox, but a modification.  Hello Mr. Dremel Tool.   [evil]

i disagree, if you have the DP ecu, you should already be throwing more air in there. your bike is probably running improperly right now

adding pods will more likely fix the bike than break it in the current state you are describing it

er: read the last few posts wrong, but as was said if it smells a bit rich you should definitely be fine adding more airflow. i have a feeling single custom maps run on the rich side as well, since running rich is better than running lean.

hang on... dont change anything. the bike with the DP ECU and free flow airkit is runnnig the right way.
adding even more air will need more fuel.
any changes he makes now... might need a mechanic with a dyno to properly change.

I'm just very confused now :-\
The bike definitely smells rich. Noticeably so.
It smelled this way after the termi install before the mechanic set the ECU & I figured once the mechanic tuned the ECU this would go away. I only put about 20 miles on between installing the termi and mechanics service & the bike actually ran fine, it just smelled rich. After the service the bike still smells rich & still runs fine.

I started thinking of deleting the airbox purely for cosmetics. But if I can do away with a stinky, rich smell that is even better.
If I had easy access to the mechanic, I would just pull the airbox, set it up the way I want and have him tune it suit. But no such luck.
Hell, for all I know all M1100 smell rich after switching to termi.

Basically, where I live, I have NO ACCESS to expertise... except for all of YOU [thumbsup]

So...THANKS VERY MUCH FOR ALL THE HELP.

what do you mean the mechanic set the ECU. as far as i know the only thing to do after installing the DP ECU is reset teh Throttle Position Sensor, which on the Siemens is merely a couple of key turns you can do yourself.

what you really need is a wideband air fuel ratio meter, because we are all just guessing if you are rich or not, by how much etc

Re-visit post #11 page 1.  Keep it simple.   [thumbsup]

Yep. You got me again. He adjusted whatever needs to be adjusted after the termi/ecu install but I thought that the TPS essentially set itself but that fuel trim has be set using DDS. I wasn't standing there while he did it so I don't know.

I maybe coming around to your way of thinking.   [beer]

Something to note... As someone mentioned, running too lean causes the bike to run hot. Many stock set ups are tuned lean for emissions reasons. However, most are tuned so lean that eventually damage can be done, particularly to the exhaust valve and seat.

I've known bikes ridden regularly and sometimes spiritedly slowly but surely lose power until they basically stopped functioning. This is because the exhaust valve and seat, which are continually blasted with super heated gases, have been actually burned away, resulting in a loss of compression, etc.

Those areas need a fair of amount of relatively cool vapor slipping over them during the overlap period and actually during induction period to ensure reliability. You can only really get a good idea of how you're air fuel mixture is doing by using something like a color tune or by running it on a dyno. How well it's running or how it smells can be very deceiving.

So...THANKS VERY MUCH FOR ALL THE HELP.



Im with you...
Im in Maui and was reliant on the Superferry for trans. back to Oahu Ducati.
just DIY'ed my Termi., ECU install and need the adjustments for that..
not to mention i got the recall to deal w/, but seems minor [bang]
Im for the dremel idea, it is quite a bit restrictive and i dont think it looks all that bad.

GL

Yep, the "outer islands" can be a PITA

cry me a river guys... you live in Hawaii...

Yep. Get that a lot.
But it has it's pluses and minuses just like everywhere else. The pluses are obvious. The minuses are things like it is going to cost me $36 to ship a $39 stebel horn from Twisted Throttle.

And one Duc mechanic in the whole state!

And it's raining today does that count?

boy, if i were a duc mech that travelled in Hawaii.. think of the business!

It really is a problem. I have an Audi & the VW dealer had an Audi mechanic...until the VW dealer closed. Found another Audi mechanic but it took me a few weeks. Then had to wait 5 more weeks for an appointment for service.

With the Monster, when I hit my 6k service, I';m going to have to crate it and send it via barge to Oahu.
And cross my fingers it doesn't get messed up or stolen during transit.

I still might start pulling bits off though.

Why not just ramp it to Oahu.  [moto]
