Ducati Monster Forum

I'm considering removing the emissions can from my '02 M620ie.
My questions are:
A) What will this do to my gas mileage?
2) Will I need to do anything else for the bike to continue running properly(ie: change the ECU Etc.)?
III) If I do it, should I disconnect the hoses at the cylinders, or just tuck them in the frasme and let them hang?

Any info will be appreciated.

To be perfectly honest the biggest upgrade will be in the looks, any other changes you will be hard pressed to notice
I would buy a Monster Emissions Removal Kit from TPO.  You need something such as the Y-splice tube to connect your vent tubes.
I would not recommend just tucking the the hoses.

TPO Emission removal kit  (http://www.tpoparts.com/catalog/product_info.php?cPath=62_74&products_id=28&osCsid=c2ff413286b14bf64c5d9bd03854251e)

A) nothing. it doesnt weigh enough to reduce overall weight by that much

here is a quick how to. covers the other questions pretty much

1 - follow hose from emissions cannister to gas tank. disconnect this hose from the emissions cannister and run it down the rear of the engine parallel to the other hose you see running back there from the tank.

2 - follow the other hose from the cannister to a "t-fitting" that splices it into two hoses. follow each of these hoses to a fitting in your intake manifolds. loosen the clamps that secure the hoses to these bleeder fittings and remove the hoses. then unscrew the bleeder fittings from the manifolds.

3 - plug the holes in the intake manifolds the those bleeder fittings left with short M5 bolts. use high-temp locktite to secure them. just "snug" tight. don't over torque 'em.

4 - unbold the cannister bracket and toss that useless P.O.S. in the garbage....

Maybe you should save it in case a cop pulls you over.  Even if you do get pulled over a cop probably wont notice but better to be safe then have to buy another emissions can!  But yeah, the TPO kit made things nice and easy for me.

Did mine last summer on a '06 620 with the TPO kit. The kit is cheap and really simple to use.  Best thing about it is they give you the spacers to go between the rearset and the frame.

good idea, you can keep it in your tank bag.......... [laugh]

sorry, dont mean to be too much of an azz.....
unless you live in CA, the emissions can is not a required item.
and even in CA, i would bet that the officer wouldn't know that it was missing

frame spacers?  ???  they don't really seem like a necessary item.

I bought two M5 bolts from the hardware store, and used the T-fitting that ran to the intakes to join my two vent tubes together.

overall cost of mod? like a dollar. plus beers.

Canister bracket fit between the frame and the 2 rear bolts of the rearset on my bike.  When you remove the braket there is a gap between the frame and the rearset - the front bolt is held out farther to account for the braket space.  It may be a different configuration on your bike.  The kit also comes with the proper size/thread set screws to bolt into the intakes.  With out these you have to leave a piece of tubing on the intake nipple and pulg it with a bolt or silicone.

05 620... I just bolted the pegs back to the frame, and had no issues w/fitting or clearance w/the high pipes I ended up running...

local hardware store carries metric fasteners  ;) so like I said, cheap mod.

Just removed my canister yesterday. My only cost was some high-temp Loctite and 30 minutes of time. Looks so much better without that thing beside the horizontal cylinder head. [thumbsup]

i am confused ??? i thought the emissions can was that ugly black box located on the front of my motor(S2R 800) but that link said something about the item near the rear sets??? what does that box do? why do i spend so much of my waking hours confused ??? ??? ??? i need to sleep [coffee]

Some models have the emissions canister tucked behind the right rearset. A far better place than out in front for everyone to see it's glorious ugliness.

correct. the DSS bikes have it behind the right foot peg, S*R have them out in front

man you guys know everything! [thumbsup]

i am alway nervous when it comes to taking things off of my motor. so let me understand this. i buy this kit and remove the ugly black box on the left side of my motor right next to the cylinder.  what is that thing supposed to do? will i have to remap? i mean i don't understand if its there in the first place, it must do something right? I mean i have already done a full system with a pc3 mapped and dyno'ed and i hope to be over with the motor mods for now, but this seems to fall into the cosmetic category. just curious.
i get scared that i will screw up something. ???

That's the idea.

it's a filter for fuel vapor from the tank, which then routes back to the bike's intake.

it basically reduces the amount that vents to atmosphere. which is good for california, and not much of an issue to the rest of us  [cheeky]

It is properly called the Evap canister (yes, evaporative emissions) but that name is misleading.

it is only required in California.

Ducati does not put it on ANY bikes except for US bikes so they can be 50-state compliant.

Just pull it.  Put hose caps over the manifold nipples and you'll need to adjust your idle a bit.  My S2R idle dropped to about 700-800 when I took it off.

No ill effects, just no stupid box hanging off the bike.

what the other folks said, but dont waste money on a kit. the bolts and rtv sealer can be had at home depot, and the rest is sweat equity  [thumbsup]

ok, just spent the last couple hours tinkering with the new s4rs....
heres my personal update....

trace the lines from the black fuel vapor canister to their fittings on the intake manifolds...

lower:

upper:
(http://i29.tinypic.com/mcy8ol.jpg)

pinch the hoseclamps loose and remove the hoses,
remove the hose nipples from the manifolds with a 12mm socket.
(http://i26.tinypic.com/6qz1uw.jpg)

replace with a M6 X.8 bolt and high temp loctite....
upper and lower cylinders of course....:P

unbolt the fuel vapor canister from the frame and drag all related hoses out....:
(http://i30.tinypic.com/330fxgz.jpg)

using a small flat-bladed screwriver, open the hoseclamp on the large hose on the bottom of the canister
trace it back through the motor and out the other side of the bike....
(http://i28.tinypic.com/2qc2pvt.jpg)

its the one that runs up to this fitting on the back of the tank....
(http://i27.tinypic.com/2q0lkc5.jpg)

look at these lines running between the rearsets and the clutch cover....
cut that hose you just traced to about the same length and fish it in there behind all the rest of them, out of the way...
all it is is a tank breather hose, just let it drain...
(http://i31.tinypic.com/35ajexc.jpg)


THIS is all the stuff youll wind up removing.....
(http://i25.tinypic.com/1zmz4lv.jpg)

and, VOILA..... aaaah thats much better.....
(http://i30.tinypic.com/5mya7r.jpg)

project costs...
2 M6 bolts = .75
1 tube loctite = 4.99
1 hour for the project, 30 minutes to get the right sized bolts for the s4rs....
youll note that the bolts i used to plug my intakes are M6 stainless, not the M5s as noted above in this post....
not sure where/ when that change took place, just thought y'all might want to note that....

I did the mod on my '06 M620.  I bought the flicker kit but it after installing it I realized how easy it is to do without the kit.  TPO does make a nice kit though, even has instructions if you are nervous.

The TPO Kit

Start by tearing out all the emissions tubing.  I was careful to not cut anything just in case it needed to go back in for some strange reason.  SAVE ALL THE HOSES TILL YOU KNOW WHAT YOU NEED TO REINSTALL THE KIT!

This is what you should end up with, or without depending on how you look at it...

I did not get pictures of the Y install for the hoses but it is super easy. Just route the two lines into the Y and leave a tail that drains out the belly of the bike.

Remove the vacuum plugs and install the bolts with loc-tite.

And voila you are done!  Performance wise no change it justs looks cleaner.

Evap emissions can and the crankcase breather are not the same thing.

the Rs has the testastretta, not the 2V aircooled motor  ;)

It's the "evaporative emissions cannister" and it's purpose is to cycle gasoline vapor that escapes the tank (in the old days, "vented" to the atmosphere) and run it through a bit of activated charcoal, helped by the vaccum from the intake manifolds.
Consequently, the "input" is  actually a vent line straight from the tank.  It doesn't always vent, and some bikes have a one-way valve (the monster, I don't know) but for that reason, paranoid old me has always been hesitant to just leave the vent line open, alongside the fuel filler vent as someone proposed.  I usually just put a little disposable plastic fuel filter just to keep crud out of the line and try to tuck it into some place that water from the road can't get into it, just in case.

I would keep it all together, just in case.  AFAIK, only CA checks, but who knows, the way things are going more and more states will begin to require some sort of inspection/emissions cert. And FWIW, you guys with FI bikes, this is low pressure vent hose, not high pressure fuel injection line, so next time you need 6" or so, don't be tempted.  ;D

just did a FAQ on emissions

Great instructions. I don't know why I left that "P.O.S."   [laugh] [laugh] [laugh] on my bike so long. Thanks!

And... I have a box of viton vacuum caps if anyone wants a set...
